6 Even so Abraham BELIEVED GOD, AND IT WAS RECKONED TO HIM AS RIGHTEOUSNESS. 7 Therefore, be sure that it is those who are of faith who are sons of Abraham. 8 The Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, "ALL THE NATIONS WILL BE BLESSED IN YOU. 9 So then those who are of faith are blessed with Abraham, the believer.
14 in order that in Christ Jesus the blessing of Abraham might come to the Gentiles, so that we would receive the promise of the Spirit through faith.
16 Now the promises were spoken to Abraham and to his seed. He does not say, "And to seeds," as referring to many, but rather to one, "And to your seed," that is, Christ.
18 For if the inheritance is based on law, it is no longer based on a promise; but God has granted it to Abraham by means of a promise.
29 And if you belong to Christ, then you are Abraham's descendants, heirs according to promise.
22 For it is written that Abraham had two sons, one by the bondwoman and one by the free woman.
