8 By an act of faith, Abraham said yes to God's call to travel to an unknown place that would become his home. When he left he had no idea where he was going. 9 By an act of faith he lived in the country promised him, lived as a stranger camping in tents. Isaac and Jacob did the same, living under the same promise. 10 Abraham did it by keeping his eye on an unseen city with real, eternal foundations - the City designed and built by God. 11 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. 12 That's how it happened that from one man's dead and shriveled loins there are now people numbering into the millions. 13 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. 14 People who live this way make it plain that they are looking for their true home. 15 If they were homesick for the old country, they could have gone back any time they wanted. 16 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. 17 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 - 18 and this after he had already been told, "Your descendants shall come from Isaac." 19 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.

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?
