11 It was by faith that even Sarah was able to have a child, though she was barren and was too old. She believed 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. 13 All these people died still believing what God had promised them. They did not receive what was promised, but they saw it all from a distance and welcomed it. They agreed that they were foreigners and nomads here on earth. 14 Obviously people who say such things are looking forward to a country they can call their own. 15 If they had longed for the country they came from, they could have gone back. 16 But they were looking for a better place, a heavenly homeland. That is why God is not ashamed to be called their God, for he has prepared a city for them. 17 It was by faith that Abraham offered Isaac as a sacrifice when God was testing him. Abraham, who had received God's promises, was ready to sacrifice his only son, Isaac, 18 even though God had told him, "Isaac is the son through whom your descendants will be counted." 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.

Commentary on Hebrews 11:8-19
(Read Hebrews 11:8-19)
We are often called to leave worldly connexions, interests, and comforts. If heirs of Abraham's faith, we shall obey and go forth, though not knowing what may befall us; and we shall be found in the way of duty, looking for the performance of God's promises. The trial of Abraham's faith was, that he simply and fully obeyed the call of God. Sarah received the promise as the promise of God; being convinced of that, she truly judged that he both could and would perform it. Many, who have a part in the promises, do not soon receive the things promised. Faith can lay hold of blessings at a great distance; can make them present; can love them and rejoice in them, though strangers; as saints, whose home is heaven; as pilgrims, travelling toward their home. By faith, they overcome the terrors of death, and bid a cheerful farewell to this world, and to all the comforts and crosses of it. And those once truly and savingly called out of a sinful state, have no mind to return into it. All true believers desire the heavenly inheritance; and the stronger faith is, the more fervent those desires will be. Notwithstanding their meanness by nature, their vileness by sin, and the poverty of their outward condition, God is not ashamed to be called the God of all true believers; such is his mercy, such is his love to them. Let them never be ashamed of being called his people, nor of any of those who are truly so, how much soever despised in the world. Above all, let them take care that they are not a shame and reproach to their God. The greatest trial and act of faith upon record is, Abraham's offering up Isaac, Genesis 22:2. There, every word shows a trial. It is our duty to reason down our doubts and fears, by looking, as Abraham did, to the Almighty power of God. The best way to enjoy our comforts is, to give them up to God; he will then again give them as shall be the best for us. Let us look how far our faith has caused the like obedience, when we have been called to lesser acts of self-denial, or to make smaller sacrifices to our duty. Have we given up what was called for, fully believing that the Lord would make up all our losses, and even bless us by the most afflicting dispensations?
