Where does the promised line of redemption begin and how far does it run?

The promised line of redemption begins at Genesis 3:15, where the seed of the woman would crush the head of the servant, and it runs all the way through Scripture as the scarlet thread of salvation. It is the continuous promise of redemption.

Les explains that this promised line of redemption is the scarlet thread of salvation. It starts with Genesis 3:15 and carries all the way through Scripture. In Genesis 3:15, the seed of the woman was going to crush the head of the servant. Les then points to Genesis chapter 12, about verse 3 or 4, where the Abrahamic covenant appears, and he notes Paul's treatment of it in Galatians. He emphasizes that this thread runs continuously through the whole Bible.

Genesis 3:15

And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.

When did God begin His plan of redemption?

The plan of redemption began immediately after Adam and Eve sinned and God lost them. At that moment He set in motion the purchase of the whole human race through the seed of the woman, revealed in Genesis 3:15. Though centuries passed before it became reality, its beginning was right after their sin.
