Romans 4
13 Ref For the promise to Abraham and to his seed that he should be heir of the world wasn't through the law, but through the righteousness of faith.
14 Ref For if those who are of the law are heirs, faith is made void, and the promise is made of no effect.
15 Ref For the law works wrath, for where there is no law, neither is there disobedience.
16 Ref For this cause it is of faith, that it may be according to grace, to the end that the promise may be sure to all the seed, not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all.
17 Ref As it is written, "I have made you a father of many nations." This is in the presence of him whom he believed: God, who gives life to the dead, and calls the things that are not, as though they were.
18 Ref Who in hope believed against hope, to the end that he might become a father of many nations, according to that which had been spoken, "So will your seed be."
