Romans 4:13-16

13For the promise to Abraham or to his descendants that he would inherit the world was not through the law, but through the righteousness that comes by faith.

14If those who are of the law are heirs, faith is made empty and the promise nullified,

15because the law produces wrath. And where there is no law, there is no transgression.

16This is why the promise is by faith, so that it may be according to grace, to guarantee it to all the descendants  — not only to the one who is of the law but also to the one who is of Abraham’s faith. He is the father of us all.
