13 For the promise to Abraham and to his offspring that he should be heir of the world wasn’t through the law, but through the righteousness of faith.
14 For if those who are of the law are heirs, faith is made void, and the promise is made of no effect.
15 For the law produces wrath, for where there is no law, neither is there disobedience.
16 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 offspring, 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 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 Besides hope, Abraham in hope believed, to the end that he might become a father of many nations, according to that which had been spoken, “So will your offspring be.”
19 Without being weakened in faith, he didn’t consider his own body, already having been worn out, (he being about a hundred years old), and the deadness of Sarah’s womb.
