Hebrews 11:11-19

By faith, barren Sarah was able to become pregnant, old woman as she was at the time, because she believed the One who made a promise would do what he said. That’s how it happened that from one man’s dead and shriveled loins there are now people numbering into the millions. * * * Each one of these people of faith died not yet having in hand what was promised, but still believing. How did they do it? They saw it way off in the distance, waved their greeting, and accepted the fact that they were transients in this world. People who live this way make it plain that they are looking for their true home. If they were homesick for the old country, they could have gone back any time they wanted. But they were after a far better country than that—heaven country. You can see why God is so proud of them, and has a City waiting for them. By faith, Abraham, at the time of testing, offered Isaac back to God. Acting in faith, he was as ready to return the promised son, his only son, as he had been to receive him—and this after he had already been told, “Your descendants shall come from Isaac.” Abraham figured that if God wanted to, he could raise the dead. In a sense, that’s what happened when he received Isaac back, alive from off the altar.
