13 All these died in faith. They did not receive what had been promised but saw it and greeted it from afar and acknowledged themselves to be strangers and aliens on earth,
14 for those who speak thus show that they are seeking a homeland.
15 If they had been thinking of the land from which they had come, they would have had opportunity to return.
16 But now they desire a better homeland, a heavenly one. Therefore, God is not ashamed to be called their God, for he has prepared a city for them.
17 By faith Abraham, when put to the test, offered up Isaac, and he who had received the promises was ready to offer his only son,
18 of whom it was said, “Through Isaac descendants shall bear your name.”
19 He reasoned that God was able to raise even from the dead, and he received Isaac back as a symbol.
