Galatians 3:7-9 AMPC
Know and understand that it is [really] the people [who live] by faith who are [the true] sons of Abraham.
And the Scripture, foreseeing that God would justify (declare righteous, put in right standing with Himself) the Gentiles in consequence of faith, proclaimed the Gospel [foretelling the glad tidings of a Savior long beforehand] to Abraham in the promise, saying, In you shall all the nations [of the earth] be blessed. [Gen. 12:3.]
So then, those who are people of faith are blessed and made happy and favored by God [as partners in fellowship] with the believing and trusting Abraham.
