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 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.’
