The history of the fall in Genesis 3 teaches us that two civilizations are destined to arise in the world. God, in Gen. 3:15 calls them respectively “your offspring“ (referring to the serpent –the devil) and “her offspring“, referring to Adam and Eve and the gospel promise to their offspring. And so it is.
In Chapter 4, the story of Cain and Abel makes that first great distinction in this regard. Abel brings his acceptable offering of worship to God. His brother Cain, born from the same mother, not only brings an unacceptable offering of worship to his Creator, but he who also becomes the first murderer in the Bible, and hence the first death is recorded in the Bible. This is deeply significant for it reveals the sad fulfilment of Genesis 2:17 of which his parents are the first cause!
We saw that Cain becomes the prototype of the ungodly offspring, as it is also recorded that “Cain went out from the presence of the LORD and settled in the land of Nod “– the land of wandering.
We saw last time that the sons of Cain became a civilization in their own right. Cain had a wife, and he founded and built a city populated with farmers that provided food and gifted craftsmen and musicians. We saw that the sons of Cain did not lack in intelligence and innovation. We also noted that it was in this first city mentioned in the Bible that God’s original plan for marriage became distorted when Cain’s grandson, Lamech married two women (4:19). Furthermore we have seen that the story of Lamech, Cain’s grandson ends with another murder.
The story of Cain leaves us with an uneasy feeling. Now that Abel the true worshipper is dead, who shall carry forward the knowledge and the ideals of true worship? How will the godly offspring be propagated in future if there is no future?
This would indeed be impossible if it were not for the fact that God kept on intervening in the history of fallen man! Aren’t you glad that He intervened in your life? And so, we are told in Gen. 4: 25-26 that Adam and Eve had another son, whom they named, Seth ( lit. appointed ). Eve said : “God has appointed for me another offspring instead of Abel, for Cain killed him.” (Gen. 4:25).
We are also told in v.26 that Seth became a father to a son called Enosh , and during that time there was a turning to God : ”at that time people began to call upon the name of the LORD.” Thus the covenant family, the godly offspring is preserved at this time.
And so we come to the 5th Chapter of Genesis and verse 1 , which begins with these words : “This is the book of the generations  (or histories) of Adam”. This chapter follows Chapter 4 , which contains the history of Cain, the offspring of the serpent. Chapter 5 is a summary statement of the history of mankind from Adam to Noah , in whose day God will send judgement on wicked men in the form of a catastrophic flood.
Chapter 5 also reveals the beginning of history of the human family of the Lord Jesus Christ. All these patriarchs here are mentioned in Luke’s genealogy of Christ. We note then that Adam and Eve, fallen people though they had become, were nevertheless the beginning of the sons and daughters of God, for God had chosen to include them into his covenant.
In verse 2 we find a repetition and restatement of the original purpose and design for man, namely the fact that man had been created (i) in the likeness of God and (ii) as male and female (iii) and blessed by God (iv) and named by God as “mankind” (5:1,2). Why this repetition? The plain answer is that God’s original design remains, even after the fall.
In the rest of the chapter (vv 3- 32) we find a record of the genealogy of the godly offspring among our pre –diluvian ancestors :
The list begins with Adam (vv.3-5). He lived 930 years and he died. V. 3 gives us an important insight. Adam fathered Seth, a son in his own likeness, after his image. We need to be reminded that the image of God in Adam is now a fallen image. This needs to be contrasted with v. 2 !
The pattern follows rhythmically : Life and death! Seth (vv. 6-8) lived 912 years and he died; Enosh lived (vv. 9-11) 905 years and he died ; Kenan (vv.12-14) lived 910 years and he died ; Mahalalel (vv.15-17) lived 895 years and he died; Jared (vv.18-20) lived 962 years and he died; Enoch (vv. 21- 24) is the grand exception! He is without years , and he has no recorded death. He was taken away by God. We will consider this in a moment. Methuselah (vv.25-27) became the oldest of the patriarchs and he died at the age of 969 years . Lamech - note , another Lamech! (vv.28-31) lived for 777 years and he died. He was the father of Noah who becomes the great subject of Genesis chapters 6 to 10 .
1. The longevity of the pre-diluvian fathers : There is a remarkable difference between the age span before the flood and after the flood. What can be the explanation for this? Some commentators see the collapse of the water canopy of Gen. 1:6-8 to be the reason for introducing harsher living conditions for mankind. The fact remains that the flood in Chapter 6 changed everything. Man’s life expectancy after the flood drops by 50 % so that the sons of Noah (who lived 950 years – Gen. 9:29) live considerably shorter. Shem lived 500 years (Gen. 11: 11) and from there we find another 50 % in the days of Peleg (Gen. 11:19) when the tower of Babel was built, and soon we find Moses saying that 70 or 80 years are the average for a human life (Psa. 90:10).
On another level we must affirm that the progressive advancement of sin has a life shortening effect upon mankind . In some modern countries the average life expectancy has been less than 50 years !
2. The second observation follows: "…and he died". The warning about ignoring the commandment in Gen. 2:17 has now become a sad reality, and the whole world has, as a result, become a graveyard.
God’s justice and wrath against sin, as well as His mercy are strongly emphasized in this chapter. Rom. 5:14 affirms that "death reigned from Adam" . The testimony of Scripture with regard to the effects of sin and disobedience is clear: “The wages of sin is death“ (Rom. 6:23) . God’s mercy is emphasised in the fact that despite sin He has mercy on who He will have mercy (Rom 9:15,16 which is quoted from Ex 33:19) . All this in implied in Genesis 3:15 ! God, the eternal Creator and the Divine Potter will redeem for Himself a people out of fallen humanity for His own glory! From our NT perspective we know that this elect people, this godly offspring has come into being not because they were better than the sons of Cain, but because God has ultimately justified them in Christ Jesus, the Lamb of God slain before the foundation of the earth!
Enoch ! (vv 5:22-24)
And now let us consider Enoch, the7th from Adam (Jude 14) of whom no death is reported. Who was this man? Now here is an interesting observation. Enoch was the seventh man from Adam ,born through the godly offspring of Seth. He stands in great contrast to Lamech (Gen. 4:18-24), the man who is the seventh from Adam through the ungodly offspring of Cain. In that sense both of these men are pre-figurements respectively of the Christ and of the anti-Christ.
Concerning Enoch we learn that he did not die. “Enoch walked with God and God took him”. (Gen. 5:24). The other man of whom this was true was Elijah(2 Kings 2) The expression "he was not"  means that he was ‘taken up‘ ( as explained in Heb. 11:5. "God took him"  which is the same word as that used in the ‘taking up’ of Elijah in 2 Kings 2:3-5.
Enoch walked with God. Literally, ‘he lived with God.’ There was an uncommon intimacy between Enoch and God. The Hebrew word used for ‘walk with God’ in our text is also used in Malachi 2:6, where Malachi speaks of the priestly tribe of Levi, which had a privileged relationship to God. Malachi says concerning Levi: “He walked with me in peace and uprightness and he turned many from iniquity.” Levi was called by God to be a priestly tribe. To the offspring of Levi alone, God gave permission to enter the Holy Place, to make intercession by sprinkling the blood of the covenant on behalf of the people of Israel, and to speak with God on behalf of Israel. The other tribes in Israel could not do that, for they were not appointed to that privileged office.
Now Enoch lived long before the twelve tribes had a list of name , his name appears mysteriously and out of the ordinary, like Melchizedek in Genesis 14 ( cf. Hebrews 7). Now Adam and Eve had the privilege of intimate communion with God in paradise, and ever since the fall, when man is banished out of the garden there is this perpetual lack of intimacy. But here is an exception: Enoch walked with God outside of paradise. He was a fallen man like you and me, and he was subjected to the same frustrations as you and me, and yet he was given the privilege to have close communion with God. Now this may fill you with holy envy. You may say: Why can’t I have that ? I remind you, you will have that. This has been recorded for you and me to encourage us how it shall be once Jesus comes to restore all things. This is the picture of the fulfilment of the gospel promise. God says to all His people in Leviticus 26: 11&12: “I will walk among you, and will be your God, and ye shall be my people.” This, we saw in our recent exposition of Revelation was what was promised in Rev.21:2&3 : “And I saw the holy city, new Jerusalem, prepared as a bride adorned for her husband; and I heard a great voice from the throne saying, Behold, the dwelling of God is with men. He will dwell with them, and they shall be his people, and God himself will be with them.”
In the meantime we walk by faith and not by sight. We walk by God’s promises and His grace in the midst of our frustrations and imperfections . We look to Jesus , the author and finisher of our faith in the midst of our poor worship habits and in the midst of our poor experiences of intimacy with Christ. Remember that Enoch was not a better man than you who love Christ. He was not a Christian superman. He was given the ability to walk with God, just as God gave the tribe of Levi the ability to walk with Him.
This chapter tells how the race of the godly offspring developed in the days before the Flood. This offspring proceeds from and by the grace of God, and not by the will of man. Man is dead in his sin; he has become a fallen being, who in the pride of his heart does not naturally reach out to His Maker. This text teaches us that God infuses grace into undeserving people .
We observed that death becomes a reality. The world becomes a cemetery. Sin has ravaging effect as seen in the decline of life span. It is seen in the reality of death.We look forward to that of which Enoch points us to: the resurrection body and eternal life, which is what we were created for by God in the first place.
