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 received power of procreation, even though he was too old—and Sarah herself was barren—because he considered him 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.”
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.” He considered the fact that God is able even to raise someone from the dead—and figuratively speaking, he did receive him back.
