14. For if they who are of the law be heirs, faith is made void, and the promise made of none effect:
15. Because the law works wrath: for where no law is, there is no transgression.
16. Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the descendants; not to those only who are of the law, but to those also who are of the faith of Abraham; who is the father of us all,

20. He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
21. And being fully persuaded that, what he had promised, he was able also to perform.
