Genesis 5

Verses 1-32

Chapter 5

Now chapter five,

This is the book of the generations of Adam. [And as you read these generations of Adam and as it lists them for us] In the day that God created man, in the likeness of God made he him; male and female created he them; and blessed them, and called their name Adam, in the day when they were created. And Adam lived one hundred and twenty years, and begat a son in his own likeness, after his image; and called his name Seth ( Genesis 5:1-3 ).

So you see Adam was a hundred and twenty years when Seth was born so that means Cain was probably in his late hundred teens. And when he killed his brother that would have given him opportunity for him to marry a ninety-year old sister. It would be no problem there at all.

And the days of Adam after he had begotten Seth were eight hundred years; and he begat sons and daughters. And the days of Adam that he lived were nine hundred and thirty years and he died ( Genesis 5:4-5 ).

Prior to the flood, man's life expectancy was much greater. They lived almost for a millennium. Methuselah came the closest, nine hundred and sixty nine years. But it would seem that the earth was protected by this moisture blanket prior to the flood and that the climactic conditions of the earth were vastly altered from what they are today. It's easy and interesting to conjecture what a great moisture blanket around the earth would do, as far as the earth's temperatures, in an equalizing of the earth's temperatures, as well as the way that the earth would be watered, with its great moisture blanket and also the protection that it would afford to cosmic radiation. We know that just a little ozone gas in the strata sphere filters out much of the ultraviolet rays of the sun. If that ozone blanket, which, of course stretches out for several miles, if it were all compressed it would only be three millimeters thick. So there is not much ozone out there protecting you and really sustaining your life forces here upon the earth.

Now we do know that at one time the earth did have a much milder climate. Of course, there is also that constant decreasing of the electromagnetic field around the earth. If the electromagnetic field has been decreasing at a constant rate since the time of Adam, the electromagnetic field would have caused the temperature of the earth, the mean temperature of the whole earth, to be much warmer than it is now.

In fact, if the decrease of the electromagnetic field, as has been measured for the last hundred and thirty six, seven years, if that is true, a constant factor, and has been for six thousand years, it would have made a vast difference in the shielding of the earth from cosmic radiation because much of the cosmic radiation is reflected or bounces off of the electromagnetic field. And also it would create a heat, but if you would take it back as much as twenty-five thousand years, the electromagnetic field around the earth would have been so strong that the earth temperatures would be about two hundred degrees Fahrenheit. If you would take it back fifty thousand years, the electromagnetic field would be so strong around the earth that the earth's temperatures would be so high that the earth would be in a molten state.

So, the scientists who believe in evolution had to do some fast thinking. They say that figures don't lie, but liars sure can figure. And they had to figure something out for this one. And so they have come up with a very interesting theory. That every five thousand years or so, by some mystical magic way, hocus pocus dominocus, the electromagnetic field gets recharged. Now they don't know how. But just every five thousand years or so the thing gets recharged, new burst of energy and then it starts declining again. It's interesting to watch them as they try to make the facts fit their theory. And sometimes they really do some real dishonest juggling.

Now as we go through these genealogies here in the fifth chapter, if you'll take a pencil and paper some time and figure it out, you'll find some interesting things. Number one, that Noah's father lived at the same time that Adam was still living. So Noah wasn't that far removed from Adam. His father was still alive while Adam was alive upon the earth. Another interesting thing is that Methuselah died in the year of the flood. Which makes it very possible that Methuselah himself was destroyed in the flood. In the genealogical records there is one exception to the whole thing and he died, and he died, and he died, until we get down to Enoch. And it says,

and he was not; for God took him ( Genesis 5:24 ).

And so Enoch breaks the chain. Enoch was a man of faith. He lived only three hundred and some years walking with God, and Enoch walked with God, a man of faith. "And he was not, for God took him." Again we have an interesting commentary on Enoch in the New Testament book of Hebrews. "By faith Enoch walked with God and he was not for God took him" ( Hebrews 11:5 ). But before God took him he had this testimony that he pleased God. What a glorious testimony! May that be the testimony of each of our lives that we pleased God.

God said concerning His Son at His baptism, "this is my beloved Son in whom I am well pleased". Jesus said, "I do always those things that please the Father". In Revelation, we are told that God has created all things and for his pleasure they are and were created. That includes you. But then Hebrews goes on to tell us, "for without faith it is impossible to please God". So we please God by our trusting Him. God is pleased when you put your trust and you commit yourself to Him.

And so through Chapter five you can work things out if you like, but now here is an interesting thing you see. Where did all of these records come from that Moses got together when he wrote this book? Writing was invented very early in the history. Prior to the writing, it came by verbal tradition. Adam no doubt told his sons, his grandsons, his great grandsons, his great, great grandsons, his great, great, great grandsons. He lived a long time. He had an opportunity to tell them.

And for a hundred years Lamech could have sat on Adam's knee, but he probably would have only done it for a few years, but at any rate, he could have sat at Adam's feet while Adam rehearsed for him the whole experience of the garden. You see he could have heard it directly from Adam. And then he told his son, Noah, who also shares it with his son Shem, and Shem was still alive when Abraham was born. So in reality, you have a link between Adam and Lamech, crossover link, Lamech then telling his son Noah, and Noah sharing with his son Shem and Shem sharing with Abraham.

Now it is true that there are other records of the flood in Babylon, Egypt, India, other accounts of creation. Most of them are gross types of exaggerated accounts. Some of them are very parallel to the biblical account. Some of them appearing in historic documents that some of the scholars say anti-date the Bible. But does it disprove the Bible because the Indians have an account of the flood and the Inca Indians have an account of the flood and the Babylonians have an account of the flood and the Egyptians have an account of the flood? Does that disprove the Bible? No.

What does it prove? It proves the common origin of man. The stories being modified, changed and amplified in many cases as they were spread through words of mouth and went to different areas, after the tower of Babel when men were scattered abroad upon the earth. But the common origin of man would then have a creation story in each of the ethnic groups. It doesn't at all disprove the biblical account, but only substantiates and proves the common origin of man. Though the skeptics would like to twist the evidence to make it show that Moses was perhaps copying the Babylonian account or whatever, which is very farfetched because if you compare the account you will find that Moses in his writing of the account, it is far different from the Babylonian, which is a very exaggerated account indeed. So if you want to look at chapter five and look at their ages and figure out who was living when, who was living and so forth, you'll find it interesting, but I don't get too excited over genealogical records.
