11. Now it is clear no one is justified before God by the law, because the righteous one will live by faith.
12. But the law is not based on faith, but the one who does the works of the law will live by them.
13. Christ redeemed us from the curse of the law by becoming a curse for us (because it is written, “Cursed is everyone who hangs on a tree”)
14. in order that in Christ Jesus the blessing of Abraham would come to the Gentiles, so that we could receive the promise of the Spirit by faith.
15. Brothers and sisters, I offer an example from everyday life: When a covenant has been ratified, even though it is only a human contract, no one can set it aside or add anything to it.
16. Now the promises were spoken to Abraham and to his descendant. Scripture does not say, “and to the descendants,” referring to many, but “and to your descendant,” referring to one, who is Christ.
17. What I am saying is this: The law that came four hundred thirty years later does not cancel a covenant previously ratified by God, so as to invalidate the promise.
18. For if the inheritance is based on the law, it is no longer based on the promise, but God graciously gave it to Abraham through the promise.
19. Why then was the law given? It was added because of transgressions, until the arrival of the descendant to whom the promise had been made. It was administered through angels by an intermediary.
20. Now an intermediary is not for one party alone, but God is one.
