Galatians 3:10-12

3:10 For all who rely on doing the works of the law are under a curse, because it is written, “Cursed is everyone who does not keep on doing everything written in the book of the law.” 3:11 Now it is clear no one is justified before God by the law, because the righteous one will live by faith. 3:12 But the law is not based on faith, but the one who does the works of the law will live by them.

Galatians 3:21

3:21 Is the law therefore opposed to the promises of God? Absolutely not! For if a law had been given that was able to give life, then righteousness would certainly have come by the law.
