CIRA international lost in christology; what hapened in Genesis 3:15?

In answer to the video "Sin and Salvation, Part 6 - Sin in Christianity"

After the tree incident, God curses the serpent with "arur atah" which is never used next when He addresses Adam and Eve. God tells them "arurah ha'adamah", cursed is the earth/ground. This speaks of the earth/ground that Adam will have to work - but God does not curse Adam nor Eve. This is the major point lost by Christians, God did not curse (arur) Adam nor Eve by causing them to unwillingly inherit a sinful nature to their descendants; they were punished (not cursed = arur) with the pain from childbirth, subjugation of women to men, and having to work for food. This has nothing to do with sin or cursing man with a sinful nature.

As to Gen3:15, the seed of Eve spoken of, refers to mankind in general because God here is addressing Eve. Similarily in Gen16:7 Hagar's seed refers to her Ishmaelite descendants because she is being addressed, not Abraham. The passage of Gen3 isnt figurative and its plain reading is obvious, refering to the enmity between serpents and humans. Some Christians like to see in that passage an allegory of Jesus' utter defeat of Satan, which obviously didnt happen. Satan is still active even among those that are most adamant in their belief in him, such as Paul 1Thess2:18. Paul also made the false prophecy that this anticipated defeat shall happen very shortly Rom16:20. 2000 years later, sin still exists, even among those that accepted Jesus, just as it remains a threat to those that sincerely repent 1Jn1:8,3:8-9.

Whether man is a sinner by nature or not is immaterial to Judaism since it teaches the way to repentance and reconciliation with God.

The Torah says man has an inclination towards evil from youth not birth Gen8:21 but that doesnt make everyone a sinner from birth, having inherited Adam's sin, nor does it mean one is in a state of being from which he must be "saved". In fact even the non Jewish king of Tyre was found to be Ezek28:15"perfect in your ways from the day you were created until wrongdoing was found in you". Each person is accountable for his own sins and can find the way to forgiveness through sincere repentance and resolve in walking aright Ezek18:20-22,Deut24:16,2Kings14:6,Jer31:30,Job34:23.
