\v 8 The scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, "In you all the nations will be blessed."
\v 10 All who rely on the works of the law are under a curse; and so it is written, "Cursed is everyone who does not abide by all the things written in the book of the law, and do them."
\v 15 Brothers, let me speak in human terms. In a man-made contract, no one can set it aside or add to it, once it is established by law.
\v 16 Now the promises were spoken to Abraham and to his descendant. It does not say, "to descendants," referring to many, but instead to only one, "and to your descendant," who is Christ.
\v 19 What, then, was the purpose of the law? It was added because of trespasses, until the descendant of Abraham would come to whom the promise had been made. The law was put into force through angels by a mediator.
\v 21 So is the law against the promises of God? Absolutely not! For if a law had been given that could give life, then righteousness would certainly have come by the law.
\v 22 But the scripture imprisoned everything under sin. God did this so that the promise to save us by faith in Jesus Christ might be given to those who believe.
