¹⁹ Abraham reasoned that if Isaac died, God was able to bring him back to life again. And in a sense, Abraham did receive his son back from the dead.

²⁰ Now all glory to God, who is able, through his mighty power at work within us, to accomplish infinitely more than we might ask or think.

¹¹ It was by faith that even Sarah was able to have a child, though she was barren and was too old. She believed^[a] that God would keep his promise. ¹² And so a whole nation came from this one man who was as good as dead—a nation with so many people that, like the stars in the sky and the sand on the seashore, there is no way to count them.

¹⁴ Still, everyone died—from the time of Adam to the time of Moses—even those who did not disobey an explicit commandment of God, as Adam did. Now Adam is a symbol, a representation of Christ, who was yet to come.

¹⁷ That is what the Scriptures mean when God told him, “I have made you the father of many nations.”^[a] This happened because Abraham believed in the God who brings the dead back to life and who creates new things out of nothing.

¹⁸ Even when there was no reason for hope, Abraham kept hoping—believing that he would become the father of many nations. For God had said to him, “That’s how many descendants you will have!”^{[b] 19} And Abraham’s faith did not weaken, even though, at about 100 years of age, he figured his body was as good as dead—and so was Sarah’s womb.

²⁰ Abraham never wavered in believing God’s promise. In fact, his faith grew stronger, and in this he brought glory to God. ²¹ He was fully convinced that God is able to do whatever he promises.
