Galatians 3:21 TLB

[21] Well then, are God's laws and God's promises against each other? Of course not! If we could be saved by his laws, then God would not have had to give us a different way to get out of the grip of sin-for the Scriptures insist we are all its prisoners. The only way out is through faith in Jesus Christ; the way of escape is open to all who believe him.
