Romans 4:13-25 - The Promise To Abraham Secured Through Faith

¹³ For the promise to Abraham and his posterity that he should inherit the world was not through the law but through the righteousness of faith. ¹⁴ For if the subjects of the law are heirs, the faith is done away and the promise abrogated. ¹⁵ For the law produces wrath; for where there is no law there is no transgression.

¹⁶ Therefore it is by faith that it may be by grace, that the promise may be sure to all the posterity, not to that of the law only but to that of the faith of Abraham, who is a father of us all, ¹⁷ as it is written, I have made you a father of many nations before God in whom he believed, who makes the dead alive and calls things which do not exist as existing.??18 who against hope believed in hope that he should become a father of many nations according to the saying shall your posterity be. ¹⁹ And being not weak in faith, he did not regard himself as dead, being now about a hundred years old, nor Sarah's incapacity for child-bearing, ²⁰ and he did not doubt the promise of God by unbelief, but was strong in faith, giving glory to God, ²¹ being fully persuaded that what he had promised he was able to perform. ²² Wherefore also it was accounted to him for righteousness. ²³ But it was not written for his sake alone, that it was accounted to him, ²⁴ but also for our sakes, to whom it is about to be accounted if we believe on him that raised Jesus our Lord from the dead, ²⁵ who was delivered up for our sins and raised for our justification.
