Hebrews 11:11-19

11And by faith even Sarah, who was past childbearing age, was enabled to bear children because she Or By faith Abraham, even though he was too old to have children—and Sarah herself was not able to conceive—was enabled to become a father because he considered him faithful who had made the promise.

12And so from this one man, and he as good as dead, came descendants as numerous as the stars in the sky and as countless as the sand on the seashore. 13All these people were still living by faith when they died. They did not receive the things promised; they only saw them and welcomed them from a distance, admitting that they were foreigners and strangers on earth. 14People who say such things show that they are looking for a country of their own. 15If they had been thinking of the country they had left, they would have had opportunity to return.

16Instead, they were longing for a better country—a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared a city for them. 17By faith Abraham, when God tested him, offered Isaac as a sacrifice. He who had embraced the promises was about to sacrifice his one and only son, 18even though God had said to him, “It is through Isaac that your offspring will be reckoned.” Gen. 21:12

19Abraham reasoned that God could even raise the dead, and so in a manner of speaking he did receive Isaac back from death.
