If after they have escaped the pollutions of the world, through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning. 2 Peter 2:20.
Some not only deny strong temptation, but even all inward evil suggestions and strivings against the same, especially in experienced Christians; but it is quite the contrary; for beginners strive generally more against the outward pollutions of the world, whilst the experienced turn their force more against their inward, spiritual iniquities.
Therefore take heed to your spirit, though your meaning be ever so good, and your assurance ever so great. Be not too high minded, for fear of falling. Beware of all sins, for the least may unawares and by degrees draw thee into many others, so as to be at last entangled in such a manner, that without great watchfulness it will be impossible to be disengaged, therefore be not deceived; flee all occasions of sin. Say not within thyself, it is no matter; it concerns only outward things, which do not belong to the essence of Christianity.
For such outward levity is a sure evidence of a false inward levity and lightness of mind. By conforming to the world we give a good handle to the enemy of souls to ruin us; and by sad experience we shall be convinced in time, that the latter end is worse than the beginning.
O for a persevering power,
To keep thy just commands;
We would defile our hearts no more;
No more pollute our hands.
