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.”[a]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.
