Galatians 3:9

¹⁶For this cause it is of faith, that it may be according to grace, to the end that the promise may be sure to all the offspring, not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all.

²⁹If you are Christ’s, then you are Abraham’s offspring and heirs according to promise.

²⁴but for our sake also, to whom it will be accounted, who believe in him who raised Jesus our Lord from the dead,

²⁸Now we, brothers, as Isaac was, are children of promise.

¹¹He received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision, that he might be the father of all those who believe, though they might be in uncircumcision, that righteousness might also be accounted to them.

¹⁴that the blessing of Abraham might come on the Gentiles through Christ Jesus, that we might receive the promise of the Spirit through faith.

⁷Know therefore that those who are of faith are children of Abraham. ⁸The Scripture, foreseeing that God would justify the Gentiles by faith, preached the Good News beforehand to Abraham, saying, “In you all the nations will be blessed.”
