Galatians 3:5-9

So again I ask, does God give you his Spirit and work miracles among you by the works of the law, or by your believing what you heard? So also Abraham “believed God, and it was credited to him as righteousness.” Understand, then, that those who have faith are children of Abraham. Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: “All nations will be blessed through you.” So those who rely on faith are blessed along with Abraham, the man of faith.
