12 The law does not use faith. It says, “A person who does these things will live forever because of them.”
13 So the law put a curse on us, but Christ took away that curse. He changed places with us and put himself under that curse. It is written in the Scriptures, “Everyone whose body is displayed on a tree is cursed.”
14 Christ did this so that God’s blessing promised to Abraham might come to the non-Jews. This blessing comes through Jesus Christ. Jesus died so that we could have the Spirit that God promised and receive this promise by believing.
15 Brothers, let me give you an example: Think about an agreement that a person makes with another person. After that agreement is accepted by both people, no one can stop that agreement or add anything to it.
16 God made promises to Abraham and his descendant. God did not say, “and to your descendants.” That would mean many people. But God said, “and to your descendant.” That means only one person; that person is Christ.
17 This is what I mean: God had an agreement with Abraham and promised to keep it. The law, which came 430 years later, cannot change God’s promise to Abraham.
18 Can following the law give us what God promised? No! If this is so, it is not God’s promise that brings us the blessings. Instead God freely gave his blessings to Abraham through the promise he had made.
