Galatians 3:7-9

So you should know that the true children of Abraham are those who have faith. The Scriptures told what would happen in the future. These writings said that God would make the non-Jewish people right through their faith. God told this Good News to Abraham before it happened. God said to Abraham, “I will use you to bless all the people on earth.” Abraham believed this, and because he believed, he was blessed. All people who believe are blessed the same as Abraham was.
