Genesis

THE WORD THAT SCATTERS FEAR

Gen_15:1 .

I

Abram was now apparently about eighty-five years old. He had been fourteen years in Palestine, and had, for the only time in his life, quite recently been driven to have recourse to arms against a formidable league of northern kings, whom, after a swift forced march from the extreme south to the extreme north of the land, he had defeated. He might well fear attack from their overwhelmingly superior forces. So this vision, like all God’s words, fits closely to moments needs, but is also for all time and all men.

1. The call to conquer fear.

Fear not.- a There is abundant reason for fear in facts of life. There are so many certain evils, and so many possible evils, that any man who is not a feather-brained fool must sometimes quail.

b Reasons for fear in our relations to divine law.

c The only rational way of conquering fears is by showing them to be unfounded. It is waste of breath to say, Don’t be afraid, and to do nothing to remove the occasions of fear. It is childish to try to get rid of fears by shutting the eyes tight and refusing to look formidable facts in the face.

d The revelation of God is the true antidote to fear.

e ‘Fear not’ is the characteristic word of divine revelation. It is of frequent occurrence from Abraham till John in Patmos.

2. The ground of the call in the Revelation of God as Shield.

a As to outward evils, His protection assures us, not of absolute exemption, but of His entire control of them, so that men and circumstances are His instruments, and His will only is powerful. Chedorlaomer and all the allied kings are nothing; ‘a noise,’ as the prophet said of a later conqueror. All the bitterness and terror is taken out of evil. If any fiery dart pass through the shield, all its poison is wiped off in passage. So there remains no reason for fear, since all things work together for good. Behind that shield we are safe as diver in his bell, though seas rave and sea-monsters swim around.

b As to inward evils, our Shield assures us of absolute exemption. ‘Shield of faith.’ Faith is shield because it takes hold of God’s strength.

3. The ground of the call in the Revelation of God as Reward. Abraham had refused all share in booty, a large sacrifice, and here he is promised, A Reward in God, i.e. He gives Himself in recompense for all sacrifices in path of duty. ‘The Lord is able to give thee much more than these.’ This promise opens out to general truth that God Himself is the true reward of a devout life. There are many recompenses for all sacrifices for God, some of them outward and material, some of them inward and spiritual, but the reward which surpasses all others is that by such sacrifices we attain to greater capacity for God, and therefore possess more of Him. This is the only Reward worth thinking of-God only satisfies the soul. With Him we are rich; without Him poor; ‘exceeding great’-’riches in glory,’ transcending all measure. The revelations of God as Shield and Reward are both given in reference to the present life, but the former applies only to earth, where ‘without are fighters, within are fears’; while ‘the latter is mainly true for heaven, where those who have fought, having God for their Shield, will possess Him for their Reward, in a measure and manner which will make all earthly experiences seem poor. Here the ‘heirs of God’ get subsistence money, which is a small instalment of their inheritance; there they enter into possession of it all.

II

Many years have passed since Abram was called to go forth from his father’s house, assured that God would make of him a great nation. They had been years of growing power. He has been dwelling at Mamre, as a prince among the people of the land, a power. There sweeps down on Southern Palestine the earliest of those invasions from the vast plains of the North which afterwards for generations were the standing dread of Abram’s descendants. Like the storm pillars in their own deserts, are these wild marauders with the wild names that never appear again in the history. Down on the rich valleys and peaceful pasture lands they swoop for booty, not for conquest. Like some sea-bird, they snatch their prey and away. They carry with them among the long train of captives Abram’s ungenerous brother-in-law, Lot. Then the friend of God, the father of the faithful, musters his men, like an Arab sheikh as he was, and swiftly follows the track of the marauders over the hills of Samaria, and across the plain of Jezreel. The night falls, and down he swoops upon them and scatters them. Coming back he had interviews with the King of Sodom, when he refuses to take any of the spoil, and with Melchizedek. Abram is back at Mamre. How natural that fear and depression should seize him: the reaction from high excitement; the dread that from the swarming East vengeance would come for his success in that night surprise; the thought that if it did, he was a wandering stranger in a strange land and could not count on allies. Then there would come, perhaps, the remembrance of how long God had delayed the very beginnings of the fulfilment, ‘Seeing I go childless.’

To this mood of mind the divine vision is addressed. ‘Fear not-I am thy shield’ whatever force comes against thee, ‘and thine exceeding great reward,’-perhaps in reference to his refusal to take anything from the spoil. But God says this to us all. In these antique words the very loftiest and purest principles of spiritual religion are set forth.

He that loves and trusts God possesses God.

He that possesses God has enough for earth.

He that possesses God has enough for heaven.

1. It is possible for a man to have God for his. ‘ I am thy Reward,’-not merely Rewarder, but Reward.

How can one spiritual Being belong to another?-plainly, By mutual love.

The Gospel assures us of God’s love, and makes it possible for ours to be fixed on Him.

Faith gives us God for ours.

The highest view of the blessings of the Gospel is that God Himself becomes our reward.

How sad the insanity of men appears, in the ordinary aims of their life, its rewards and its objects of desire! How they chase after variety!

How much loftier and truer a conception of the blessing of religion this is than notions of mere escape and the like!

2. The possession of God is enough for earth.

God the all-sufficient object for our spirits, His love, the communication of Himself, the sense of His presence, the depths of His infinite character, of His wondrous ways, of His revealed Truth as an object for thought: of His authoritative will as imperative for will and conscience: aspiration towards Him.

God the Eternal Object.

To find Him in everything, and everything in Him, is to be at rest.

This is what He promises-

Not a life of outward success and ease-much nobler than if He did.

Take Abram’s as a type.

In war He will be our Defence.

In absence of other joys He will be Enough.

Sphered and included in Him is all sweetness. He sustains all relations, and does for us what these other joys and goods partially do.

The possession of His love should put away all fear, since having Him we are not at the mercy of externals.

What, then, is Life as men ordinarily make it?-what a blunder!

3. To possess God is enough for heaven.

Such a relationship is the great proof of immortality.

Christ and Sadducees.

The true glory of heaven is in fuller possession of God: no doubt other things, but these subsidiary.

The Reward is God.

The idea of recompense ample and full for all sorrow.

More than adequate wages for all work.

That final reward will show how wise the wanderer was, who left his father’s house and ‘looked for a city.’ God is not ashamed to be called their God.

Christ comes to us-offers Himself.

Think of how rich with Him, and oh, think of how poor without Him!

Which will you have on earth?

Which will you have in another world?

Verse 5

Genesis

GOD’S COVENANT WITH ABRAM

Gen_15:5 - Gen_15:18 .

1. Abram had exposed himself to dangerous reprisals by his victory over the confederate Eastern raiders. In the reaction following the excitement of battle, dread and despondency seem to have shadowed his soul. Therefore the assurance with which this chapter opens came to him. It was new, and came in a new form. He is cast into a state of spiritual ecstasy, and a mighty ‘word’ sounds, audible to his inward ear. The form which it takes-’I am thy shield’-suggests the thought that God shapes His revelation according to the moment’s need. The unwarlike Abram might well dread the return of the marauders in force, to avenge their defeat. Therefore God speaks to his fears and present want. Just as to Jacob the angels appeared as a heavenly camp guarding his undefended tents and helpless women; so, here and always, God is to us what we most need at the moment, whether it be comfort, or wisdom, or guidance, or strength. The manna tasted to each man, as the rabbis say, what he most desired. God’s gifts take the shape of man’s necessity.

Abram had just exercised singular generosity in absolutely refusing to enrich himself from the spoil. God reveals Himself as ‘his exceeding great reward.’ He gives Himself as recompense for all sacrifices. Whatever is given up at His bidding, ‘the Lord is able to give thee much more than this.’ Not outward things, nor even an outward heaven, is the guerdon of the soul; but a larger possession of Him who alone fills the heart, and fills the heart alone. Other riches may be counted, but this is ‘exceeding great,’ passing comprehension, and ever unexhausted, and having something over after all experience. Both these aspects of God’s preciousness are true for earth; but we need a shield only while exposed to attack. In the land of peace, He is only our reward.

2. Mark the triumphant faith which wings to meet the divine promise. The first effect of that great assurance is to deepen Abram’s consciousness of the strange contradiction to it apparently given by his childlessness. It is not distrust that answers the promise with a question, but it is eagerness to accept the assurance and ingenuous utterance of difficulties in the hope of their removal. God is too wise a father not to know the difference between the tones of confidence and unbelief, however alike they may sound; and He is too patient to be angry if we cannot take in all His promise at once. He breaks it into bits not too large for our lips, as He does here. The frequent reiterations of the same promises in Abram’s life are not vain. They are a specimen of the unwearied repetition of our lessons, ‘Here a little, there a little,’ which our teacher gives His slow scholars. So, once more, Abram gets the promise of posterity in still more glorious form. Before, it was likened to the dust of the earth; now it is as the innumerable stars shining in the clear Eastern heaven. As he gazes up into the solemn depths, the immensity and peace of the steadfast sky seems to help him to rise above the narrow limits and changefulness of earth, and a great trust floods his soul. Abram had lived by faith ever since he left Haran; but the historian, usually so silent about the thoughts of his characters, breaks through his usual manner of narrative to insert the all-important words which mark an epoch in revelation, and are, in some aspects, the most significant in the Old Testament. Abram ‘believed in the Lord; and He counted it to him for righteousness.’

Observe the teaching as to the nature and object of faith in that first clause. The word rendered ‘believed’ literally means to steady oneself by leaning on something. So it gives in a vivid picture more instructive than many a long treatise what faith is, and what it does for us. As a man leans his trembling hand on a staff, so we lay our weak and changeful selves on God’s strength; and as the most mutable thing is steadied by being fastened to a fixed point, so we, though in ourselves light as thistledown, may be steadfast as rock, if we are bound to the rock of ages by the living band of faith. The metaphor makes it plain that faith cannot be merely an intellectual act of assent, but must include a moral act, that of confidence. Belief as credence is mainly an affair of the head, but belief as trust is an act of the will and the affections.

The object of faith is set in sunlight clearness by these words,-the first in which Scripture speaks of faith. Abram leaned on ‘the Lord.’ It was not the promise, but the promiser, that was truly the object of Abram’s trust. He believed the former, because he trusted Him who made it. Many confusions in Christian teaching would have been avoided if it had been always seen that faith grasps a person, not a doctrine, and that even when the person is revealed by doctrine, it is him, and not only it, which faith lays hold of. Whether God speaks promises, teachings of truth, or commandments, faith accepts them, because it trusts Him. Christ is revealed to us for our faith by the doctrinal statements of the New Testament. But we must grasp Himself, as so revealed, if we are to have faith which saves the soul. This same thought of the true object of faith as personal helps us to understand the substantial identity of faith in all ages and stages of revelation, however different the substance of the creeds. Abram knew very little of God, as compared with our knowledge. But it was the same God whom Abram trusted, and whom we trust as made known in His Son. Hence we can stretch out our hands across the ages, and clasp his as partaker of ‘like precious faith.’ We walk in the light of the same sun,-he in its morning beams, we in its noonday glory. There has never been but one road to God, and that is the road which Abram trod, when ‘he believed in the Lord.’

3. Mark the full-orbed gospel truth as to the righteousness of faith which is embedded in this record of early revelation, ‘He counted it to him for righteousness.’ A geologist would be astonished if he came on remains in some of the primary strata which indicated the existence, in these remote epochs, of species supposed to be of much more recent date. So here we are startled at finding the peculiarly New Testament teaching away back in this dim distance. No wonder that Paul fastened on this , which so remarkably breaks the flow of the narrative, as proof that his great principle of justification by faith was really the one only law by which, in all ages, men had found acceptance with God. Long before law or circumcision, faith had been counted for righteousness. The whole Mosaic system was a parenthesis; and even in it, whoever had been accepted had been so because of his trust, not because of his works. The whole of the subsequent divine dealings with Israel rested on this act of faith, and on the relation to God into which, through it, Abram entered. He was not a perfectly righteous man, as some passages of his life show; but he rose here to the height of loving and yearning trust in God, and God took that trust in lieu of perfect conformity to His will. He treated and regarded him as righteous, as is proved by the covenant which follows. The gospel takes up this principle, gives us a fuller revelation, presents the perfect righteousness of Christ as capable of becoming ours by faith, and so unveils the ground on which Abram and the latest generations are equally ‘accepted in the beloved.’ This reckoning of righteousness to the unrighteous, on condition of their faith, is not because of any merit in faith. It does not come about in reward of, but by means of, their faith, which is nothing in itself, but is the channel only of the blessing. Nor is it a mere arbitrary act of God’s, or an unreal imputing of what is not. But faith unites with Christ; and ‘he that is joined to the Lord is one spirit,’ so as that ‘in Him we have redemption.’ His righteousness becomes ours. Faith grafts us into the living Vine, and we are no longer regarded in our poor sinful individual personality, but as members of Christ. Faith builds us into the rock; but He is a living Stone, and we are living stones, and the life of the foundation rises up through all the courses of the great temple. Faith unites sinful men to God in Christ; therefore it makes them partakers of the ‘blessedness of the man, . . .to whom the Lord will not impute sin,’ and of the blessedness of the man to whom the Lord reckons his faith for righteousness. That same faith which thus clothes us with the white robe of Christ’s righteousness, in lieu of our own tattered raiment, also is the condition of our becoming righteous by the actual working out in our character of all things lovely and of good report. It opens the heart to the entrance of that divine Christ, who is first made for us, and then, by daily appropriation of the law of the spirit of life, is made in us, ‘righteousness and sanctification, and redemption.’ May all who read these lines ‘be found in Him,’ having ‘that which is through the faith of Christ, the righteousness which is of God by faith!’

4. Consider the covenant which is the consequence of Abram’s faith, and the proof of his acceptance.

It is important to observe that the whole remainder of this chapter is regarded by the writer as the result of Abram’s believing God. The way in which Gen_15:7 and the rest are bolted on, as it were, to Gen_15:6 , clearly shows this. The nearer lesson from this fact is, that all the Old Testament revelation from this point onward rests on the foundation of faith. The further lesson, for all times, is that faith is ever rewarded by more intimate and loving manifestations of God’s friendship, and by fuller disclosure of His purposes. The covenant is not only God’s binding Himself anew by solemn acts to fulfil His promises already made, but it is His entering into far sweeter and nearer alliance with Abram than even He had hitherto had. That name, ‘the friend of God,’ by which he is still known over all the Mohammedan world, contains the very essence of the covenant. In old days men were wont to conclude a bond of closest amity by cutting their flesh and interchanging the flowing blood. Henceforth they had, as it were, one life. We have not here the shedding of Abram’s blood, as in the covenant of circumcision. Still, the slain animals represent the parties to the covenant, and the notion of a resulting unity of the closest order as between God and Abram is the very heart of the whole incident.

The particulars as to the rite by which the covenant was established are profoundly illuminative. The significant division of the animals into two shows that they were regarded as representing the contracting parties, and the passing between them symbolised the taking up of the obligations of the covenant. This strange rite, which was widely spread, derives importance from the use of it probably made in Heb_9:16 - Heb_9:17 . The new covenant, bringing still closer friendship and higher blessings, is sealed by the blood of Christ. He represents both God and man. In His death, may we not say that the manhood and the Godhead are parted, and we, standing as it were between them, encompassed by that awful sacrifice, and enclosed in its mysterious depths, enter into covenant with God, and become His friends?

We need not to dwell upon the detailed promises, of which the covenant was the seal. They are simply the fuller expansion of those already made, but now confirmed by more solemn guarantees. The new relation of familiar friendship, established by the covenant itself, is the main thing. It was fitting that God’s friend should be in the secret of His purposes. ‘The servant knoweth not what his lord doeth,’ but the friend does. And so we have here the assurance that faith will pierce to the discernment of much of the mind of God, which is hid from sense and the wisdom of this world. If we would know, we must believe. We may be ‘men of God’s counsel,’ and see deeply into the realities of the present, and far ahead into what will then become the certainties of the future, if only we live by faith in the secret place of the Most High, and, like John, lean so close on the Master’s bosom that we can hear His lowest whisper.

Notice, too, the lessons of the smoking furnace and the blazing torch. They are like the pillar of fire and cloud. Darkness and light; a heart of fire and a wrapping of darkness,-these are not symbols of Israel and its checkered fate, as Dean Stanley thinks, but of the divine presence: they proclaim the double aspect of all divine manifestations, the double element in the divine nature. He can never be completely known; He is never completely hid. Ever does the lamp flame; ever around it the smoke wreathes. In all His self-revelation is ‘the hiding of His power’; after all revelation He dwelleth ‘in the thick darkness.’ Only the smoke is itself fire, but not illumined to our vision. The darkness is light inaccessible. Much that was ‘smoke’ to Abram has caught fire, and is ‘light’ to us. But these two elements will ever remain; and throughout eternity God will be unknown, and yet well known, pouring Himself in ever-growing radiance on our eyes, and yet ‘the King invisible.’

Nor is this all the teaching of the symbol. It speaks of that twofold aspect of the divine nature, by which to hearts that love He is gladsome light, and to unloving ones He is threatening darkness. As to the Israelites the pillar was light, and to the Egyptians darkness and terror; so the same God is joy to some, and dread to others. ‘What maketh heaven, that maketh hell.’ Light itself can become the source of pain the most exquisite, if the eye is diseased. God Himself cannot but be a torment to men who love darkness rather than light. Love and wrath, life and death, a God who pities and who cannot but judge, are solemnly proclaimed by that ancient symbol, and are plainly declared to us in the perfect revelation in Christ Jesus.

Observe, too, the manner of the ratification of the covenant. The symbol of the Divine presence passed between the pieces. No mention is made of Abram’s doing so. Why this one-sided covenant? Because God’s gracious dealings with men are one-sided. He seeks no oaths from us; He does not exchange blessings for our gifts. His covenant is the free result of His unmotived love, and is ratified by a solemn sacrifice, which we do not offer. We have nothing to do but to take what He gives. All ideas of barter and bargain are far from Him. Our part is but to embrace His covenant, which is complete and ratified whether we embrace it or not. What a wonderful thought that is of a covenant-making and a covenant-keeping God! We do not hear so much of it as our fathers did. The more is the pity. It means that God has, as it were, buoyed out across the boundless ocean of His possible modes of action a plain course, which He binds Himself to keep; that He has frankly let us into the very secret of His doings; that He has stooped to use human forms of assurance to make it easier to trust Him; that He has confirmed His promise by a mighty sacrifice. Therefore we may enter into closest friendship with Him, and take for our own the exultant swan-song of Abram’s royal son: ‘Although my house be not so with God [although my life be stained, and my righteousness unfit to be offered to His pure eyes]; yet He hath made with me an everlasting covenant, ordered in all things, and sure: for this is all my salvation, and all my desire.’

Verse 6

Genesis

GOD’ S COVENANT WITH ABRAM

FAITH AND RIGHTEOUSNESS

Gen_15:6 .

It is remarkable to find this anticipation of New Testament teaching so far back. It is like finding one full-blown flower in a garden where all else is but swelling into bud. No wonder that Paul fastened on it to prove that justification by faith was older than Moses, than law or circumcision, that his teaching was the real original, and that faith lay at the foundation of the Old Testament religion.

1. The Nature of Faith. -The metaphor in the Hebrew word is that of a man leaning all his weight on some strong stay. Surely that metaphor says more than many definitions. It teaches that the essence of faith is absolute reliance, and that unites us with Him on whom we rely. Its result will be steadfastness. We are weak, mobile, apt to be driven hither and thither, but light things lashed to fixed things become fixed. So ‘reeds shaken with wind’ are changed into iron pillars.

2. The Object of Faith. -’Lord.’ It is a Person, not the promise but the Promiser. Of course, reliance on the Person results in acceptance of His word, and here it is God’s word as to the future. Our faith has to do with the future, but also with the past. Its object is Christ, the historic Christ, the living Christ, the Christ who will come again. How clear the nature of faith becomes when its object is clear! It cannot be mere assent, but trust. How clear becomes its identity in all ages! The creeds may be different in completeness, but the object of faith is the same, and the emotion is the same.

3. The effect of Faith. -Righteous is conformity to the will of God. Abram was not righteous, but he yielded himself to God and trusted Him, and God accepted that as the equivalent of righteousness. The acceptance was shown by the Covenant, and by the fulfilment of the promises.

So here is the great truth that faith is accepted for righteous. It is rightly regarded and treated as righteous, by the estimate of God, who estimates things as they really are. It is righteousness, for-

a Faith is itself a supreme act of righteousness, as being accordant with God’s supreme desire for man.

b Faith unites with Christ the righteous.

c Faith will blossom out into all righteousness.

It is important to observe that the whole remainder of this chapter is regarded by the writer as the result of Abram’s believing God. The way in which Gen_15:7 and the rest are bolted on, as it were, to Gen_15:6 , clearly shows this. The nearer lesson from this fact is, that all the Old Testament revelation from this point onward rests on the foundation of faith. The further lesson, for all times, is that faith is ever rewarded by more intimate and loving manifestations of God’s friendship, and by fuller disclosure of His purposes. The covenant is not only God’s binding Himself anew by solemn acts to fulfil His promises already made, but it is His entering into far sweeter and nearer alliance with Abram than even He had hitherto had. That name, ‘the friend of God,’ by which he is still known over all the Mohammedan world, contains the very essence of the covenant. In old days men were wont to conclude a bond of closest amity by cutting their flesh and interchanging the flowing blood. Henceforth they had, as it were, one life. We have not here the shedding of Abram’s blood, as in the covenant of circumcision. Still, the slain animals represent the parties to the covenant, and the notion of a resulting unity of the closest order as between God and Abram is the very heart of the whole incident.

The particulars as to the rite by which the covenant was established are profoundly illuminative. The significant division of the animals into two shows that they were regarded as representing the contracting parties, and the passing between them symbolised the taking up of the obligations of the covenant. This strange rite, which was widely spread, derives importance from the use of it probably made in Heb_9:16 - Heb_9:17 . The new covenant, bringing still closer friendship and higher blessings, is sealed by the blood of Christ. He represents both God and man. In His death, may we not say that the manhood and the Godhead are parted, and we, standing as it were between them, encompassed by that awful sacrifice, and enclosed in its mysterious depths, enter into covenant with God, and become His friends?

We need not to dwell upon the detailed promises, of which the covenant was the seal. They are simply the fuller expansion of those already made, but now confirmed by more solemn guarantees. The new relation of familiar friendship, established by the covenant itself, is the main thing. It was fitting that God’s friend should be in the secret of His purposes. ‘The servant knoweth not what his lord doeth,’ but the friend does. And so we have here the assurance that faith will pierce to the discernment of much of the mind of God, which is hid from sense and the wisdom of this world. If we would know, we must believe. We may be ‘men of God’s counsel,’ and see deeply into the realities of the present, and far ahead into what will then become the certainties of the future, if only we live by faith in the secret place of the Most High, and, like John, lean so close on the Master’s bosom that we can hear His lowest whisper.

Notice, too, the lessons of the smoking furnace and the blazing torch. They are like the pillar of fire and cloud. Darkness and light; a heart of fire and a wrapping of darkness,-these are not symbols of Israel and its checkered fate, as Dean Stanley thinks, but of the divine presence: they proclaim the double aspect of all divine manifestations, the double element in the divine nature. He can never be completely known; He is never completely hid. Ever does the lamp flame; ever around it the smoke wreathes. In all His self-revelation is ‘the hiding of His power’; after all revelation He dwelleth ‘in the thick darkness.’ Only the smoke is itself fire, but not illumined to our vision. The darkness is light inaccessible. Much that was ‘smoke’ to Abram has caught fire, and is ‘light’ to us. But these two elements will ever remain; and throughout eternity God will be unknown, and yet well known, pouring Himself in ever-growing radiance on our eyes, and yet ‘the King invisible.’

Nor is this all the teaching of the symbol. It speaks of that twofold aspect of the divine nature, by which to hearts that love He is gladsome light, and to unloving ones He is threatening darkness. As to the Israelites the pillar was light, and to the Egyptians darkness and terror; so the same God is joy to some, and dread to others. ‘What maketh heaven, that maketh hell.’ Light itself can become the source of pain the most exquisite, if the eye is diseased. God Himself cannot but be a torment to men who love darkness rather than light. Love and wrath, life and death, a God who pities and who cannot but judge, are solemnly proclaimed by that ancient symbol, and are plainly declared to us in the perfect revelation in Christ Jesus.

Observe, too, the manner of the ratification of the covenant. The symbol of the Divine presence passed between the pieces. No mention is made of Abram’s doing so. Why this one-sided covenant? Because God’s gracious dealings with men are one-sided. He seeks no oaths from us; He does not exchange blessings for our gifts. His covenant is the free result of His unmotived love, and is ratified by a solemn sacrifice, which we do not offer. We have nothing to do but to take what He gives. All ideas of barter and bargain are far from Him. Our part is but to embrace His covenant, which is complete and ratified whether we embrace it or not. What a wonderful thought that is of a covenant-making and a covenant-keeping God! We do not hear so much of it as our fathers did. The more is the pity. It means that God has, as it were, buoyed out across the boundless ocean of His possible modes of action a plain course, which He binds Himself to keep; that He has frankly let us into the very secret of His doings; that He has stooped to use human forms of assurance to make it easier to trust Him; that He has confirmed His promise by a mighty sacrifice. Therefore we may enter into closest friendship with Him, and take for our own the exultant swan-song of Abram’s royal son: ‘Although my house be not so with God [although my life be stained, and my righteousness unfit to be offered to His pure eyes]; yet He hath made with me an everlasting covenant, ordered in all things, and sure: for this is all my salvation, and all my desire.’
