Galatians 3:7, 9, 29

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.

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.

And if you belong to Christ [if you are in Him], then you are Abraham’s descendants, and [spiritual] heirs according to [God’s] promise.
