Galatians 3:7-9

So understand that it is the people who live by faith [with confidence in the power and goodness of God] who are [the true] sons of Abraham. 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.
