Galatians 3:6; Galatians 3:8; Galatians 3:10-13; Galatians 3:16
Consider Abraham: "He believed God, and it was credited to him as righteousness."
The 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."
All who rely on observing the law are under a curse, for it is written: "Cursed is everyone who does not continue to do everything written in the Book of the Law."
Clearly no one is justified before God by the law, because, "The righteous will live by faith."
The law is not based on faith; on the contrary, "The man who does these things will live by them."
Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: "Cursed is everyone who is hung on a tree."
The promises were spoken to Abraham and to his seed. The Scripture does not say "and to seeds," meaning many people, but "and to your seed," meaning one person, who is Christ.
