Galatians 3:13

For as many as are of the works of the law are under a curse. For it is written, “Cursed is everyone who doesn’t continue in all things that are written in the book of the law, to do them.”

Now that no man is justified by the law before God is evident, for, “The righteous will live by faith.”

The law is not of faith, but, “The man who does them will live by them.”

that the blessing of Abraham might come on the Gentiles through Christ Jesus, that we might receive the promise of the Spirit through faith.

Brothers, speaking of human terms, though it is only a man’s covenant, yet when it has been confirmed, no one makes it void or adds to it.

Now the promises were spoken to Abraham and to his offspring. He doesn’t say, “To descendants”, as of many, but as of one, “To your offspring”, which is Christ.
