Galatians 3:8-9, 14

The Scripture, foreseeing that God would justify the Gentiles by faith, proclaimed the good news [of the Savior] to Abraham in advance [with this promise], saying, “IN YOU SHALL ALL THE NATIONS BE BLESSED.” [Gen 12:3] So then those who are people of faith [whether Jew or Gentile] are blessed and favored by God [and declared free of the guilt of sin and its penalty, and placed in right standing with Him] along with Abraham, the believer.

in order that in Christ Jesus the blessing of Abraham might also come to the Gentiles, so that we would all receive [the realization of] the promise of the [Holy] Spirit through faith.
