When you think of yourself, would you say you are a child of Abraham? On the surface you may say, NO! But if you dig deeper you may see some striking similarities in your temperament and psychology to his, and if you are a follower of Jesus by faith, then Paul says you definitely are one of his descendants (Gal. 3:7, 9). God called him, and God called you to follow him. If you are his child then you are blessed (Gal. 3:9)! 

Some Jewish Christians in Galatia wanted the new non-Jewish (Gentile) followers of Jesus to keep the Old Testament law. But Paul says that places them under a curse (Gal. 3:10) just like Israel has been. Israel was cursed because they couldn’t keep the law. God was so concerned about this that Christ came to redeem (deliver or liberate) those who were under that curse (Gal. 3:13). Why? So that everyone could enjoy his blessing!
