Romans 4:14-16

14For if those who live by the law are heirs, faith is useless and the promise is worthless, 15because the law brings wrath. And where there is no law, there is no transgression.

16Therefore, the promise comes by faith, so that it may rest on grace and may be guaranteed to all Abraham’s offspring—not only to those who are of the law, but also to those who are of the faith of Abraham. He is the father of us all.
