First reading
Faith is the assurance of things hoped for, the conviction of things not seen. Indeed, by faith our ancestors received approval.
By faith Abraham obeyed when he was called to set out for a place that he was to receive as an inheritance; and he set out, not knowing where he was going. By faith he stayed for a time in the land he had been promised, as in a foreign land, living in tents, as did Isaac and Jacob, who were heirs with him of the same promise. For he looked forward to the city that has foundations, whose architect and builder is God.
By faith Sarah herself, though barren, received power to conceive, even when she was too old, because she considered God faithful who had promised.
Therefore from one person, and this one as good as dead, descendants were born, “as many as the stars of heaven and as the innumerable grains of sand by the seashore.”
All of these died in faith without having received the promises, but from a distance they saw and greeted them. They confessed that they were strangers and foreigners on the earth, for people who speak in this way make it clear that they are seeking a homeland. If they had been thinking of the land that they had left behind, they would have had opportunity to return.
But as it is, they desire a better country, that is, a heavenly one. Therefore God is not ashamed to be called their God; indeed, he has prepared a city for them.
By faith Abraham, when put to the test, offered up Isaac. He who had received the promises was ready to offer up his only son, of whom he had been told, “It is through Isaac that descendants shall be named for you.” Abraham considered the fact that God is able even to raise someone from the dead — and figuratively speaking, he did receive Isaac back.
