Reading the book of Adam and Eve a person can get some idea of who humans were then and what they may of physically been like. The glorified image of Man made even the angels tremble. The beauty of eve made the wicked angels of satan envious and they wanted to corrupt the image of eve so they could fornicate with her. When Adam and Eve sinned they physical image of mankind began to change. Sin begat death and sickness. Our existance on earth was no longer the glorified image God intended us to be. Adam and Eve were disrought from having been cast out of the garden their flesh no longer illumined and protected from aging. Thier posture bowed down low because of sin. They were not as high and holy as they originally were created. The many generations of mankind changed our likeliness into carnal animal like creatures without a holy birth such as Adam or Eve. Because the only freedom from the dark and carnal birth is by faith in Jesus Christ who is the first and last who's crucifixion freed us from the death of eve . He is the eternally begotton and express image of our creator . God from God manifest in the flesh. Because he lives and reigns on throne established forever. Our carnal birth we cannot boast in. Our genetics fall short of the Glory of God. Our flesh becomes new skin so to speak when we put to death our old image the life of the flesh we were born as. The new life we live is in the spirit and freed from the sin and death yet our flesh becomes crucified with christ meaning our genetics are nothing we can boast in just the salvation of our flesh and justice that we will have eternal life and new body in heaven that is uncorrupted by sin.
Look in 3:4 of phillipians paul states that he had more reason to boast of his genetics because of the decent of his birth and the time. He was of the tribe of benjamin the same as jesus and had to bow before christ and become his desciple learning that to become a righteous man he had to recieve jesus christ as Lord and Master
3:1 Finally, my brothers, rejoice in the Lord. To write the same things to you, to me indeed is not tiresome, but for you it is safe.
3:2 Beware of the dogs, beware of the evil workers, beware of the false circumcision.
3:3 For we are the circumcision, who worship God in the Spirit, and rejoice in Christ Jesus, and have no confidence in the flesh;
3:4 though I myself might have confidence even in the flesh. If any other man thinks that he has confidence in the flesh, I yet more:
3:5 circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; concerning the law, a Pharisee;
3:6 concerning zeal, persecuting the assembly; concerning the righteousness which is in the law, found blameless.
3:7 However, what things were gain to me, these have I counted loss for Christ.
3:8 Yes most assuredly, and I count all things to be loss for the excellency of the knowledge of Christ Jesus, my Lord, for whom I suffered the loss of all things, and count them nothing but refuse, that I may gain Christ
3:9 and be found in him, not having a righteousness of my own, that which is of the law, but that which is through faith in Christ, the righteousness which is from God by faith;
3:10 that I may know him, and the power of his resurrection, and the fellowship of his sufferings, becoming conformed to his death;
3:11 if by any means I may attain to the resurrection from the dead.
3:12 Not that I have already obtained, or am already made perfect; but I press on, if it is so that I may take hold of that for which also I was taken hold of by Christ Jesus.
3:13 Brothers, I don't regard myself as yet having taken hold, but one thing I do. Forgetting the things which are behind, and stretching forward to the things which are before,
3:14 I press on toward the goal for the prize of the high calling of God in Christ Jesus.
3:15 Let us therefore, as many as are perfect, think this way. If in anything you think otherwise, God will also reveal that to you.
3:16 Nevertheless, to the extent that we have already attained, let us walk by the same rule. Let us be of the same mind.
3:17 Brothers, be imitators together of me, and note those who walk this way, even as you have us for an example.
3:18 For many walk, of whom I told you often, and now tell you even weeping, as the enemies of the cross of Christ,
3:19 whose end is destruction, whose god is the belly, and whose glory is in their shame, who think about earthly things.
3:20 For our citizenship is in heaven, from where we also wait for a Savior, the Lord Jesus Christ;
3:21 who will change the body of our humiliation to be conformed to the body of his glory, according to the working by which he is able even to subject all things to himself.
