By faith Abraham, when called to go to a place he would later receive as his inheritance, obeyed and went, even though he did not know where he was going.
By faith he made his home in the promised land like a stranger in a foreign country; he lived in tents, as did Isaac and Jacob, who were heirs with him of the same promise.
For he was looking forward to the city with foundations, whose architect and builder is God.
By faith Abraham, even though he was past age--and Sarah herself was barren--was enabled to become a father because he considered him faithful who had made the promise.
And 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.
All 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. And they admitted that they were aliens and strangers on earth.
People who say such things show that they are looking for a country of their own.
If they had been thinking of the country they had left, they would have had opportunity to return.
Instead, 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.
By faith Abraham, when God tested him, offered Isaac as a sacrifice. He who had received the promises was about to sacrifice his one and only son,
even though God had said to him, "It is through Isaac that your offspring will be reckoned."
Abraham reasoned that God could raise the dead, and figuratively speaking, he did receive Isaac back from death.
