What is the scarlet thread of salvation that starts in Genesis 3:15 and runs through Scripture?
The scarlet thread of salvation is the promised line of redemption beginning in Genesis 3:15, where the seed of the woman would crush the head of the servant. It carries through Scripture, including the Abrahamic covenant and the promise that Christ comes from the seed of David according to the flesh.
Les explains that Paul was uniquely called of God to be the Apostle of the Gentiles, not one of many, and others would follow in his footsteps, but Paul is the one to whom we must go for basic doctrines. In Romans 1:2, God had promised before by His prophets in the Holy Scriptures concerning His Son, Jesus Christ our Lord, who is made of the seed of David according to the flesh. Les connects this to Genesis 3:15, the seed of the woman, and says that was the promised line of redemption, the scarlet thread of salvation that starts with Genesis 3:15 and carries all the way through Scripture. The seed of the woman would crush the head of the servant. Les then notes the Abrahamic covenant in Genesis chapter 12 and Paul in Galatians.
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.
