Just as Abraham "believed God, and it was counted to him as righteousness"
Know then that it is those of faith who are the sons of Abraham. And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying,
"In you shall all the nations be blessed."
So then, those who are of faith are blessed along with Abraham, the man of faith.
Galatians 3:6-10 ESV
