Not only was Jesus the seed of Abraham, he was not of the crooked and perverse seed of Adam (Ecclesiastes 1:2,13-17; 7:13; Romans 1:24-32; 3:9; 5:12-19; 8:19-22; 2 Peter 1:4), so he was additionally a human "Son of God" as was Adam before Adam sinned. (Luke 3:38) Jesus was begotten of the holy spirit -- not as a spirit being, but as a human being -- in the womb of Mary (Matthew 1:20), and his body was prepared by God. (Hebrews 10:5) Thus, he was not born "under the sun" of vanity, with its present futility (Ecclesiastes 1:2,14,15; Romans 8:20); Jesus was indeed a new creation, and became a new sun, a "sun of righteousness." -- Malachi 4:2.
Nevertheless, to pay the price for sin, Jesus suffered as though he were under that bondage of corruption. Furthermore, the seed of the woman is not just Jesus, for it includes those who, by application of the blood of the new covenant before the age to come, are allowed to come into covenant God made with Jesus through Abraham. (Matthew 26:28; Mark 14:24; Luke 22:20; Galatians 3:16,29; Hebrews 6:5; 10:14,29; 12:24) It is for the revealing of this seed of the woman that the nations -- the heathen -- the whole creation now groaning in travail and pain (Romans 8:22), is waiting for, since when the seed is revealed all nations will then be blessed, so that the whole groaning creation itself also will be delivered from the bondage of corruption into the liberty of the glory of the children of God. -- Genesis 22:18; Isaiah 2:2-4; Romans 8:19-22.
