Hebrews 11:8-12

11:8 By faith Abraham obeyed when he was called to go out to a place he would later receive as an inheritance, and he went out without understanding where he was going. 11:9 By faith he lived as a foreigner in the promised land as though it were a foreign country, living in tents with Isaac and Jacob, who were fellow heirs of the same promise. 11:10 For he was looking forward to the city with firm foundations, whose architect and builder is God. 11:11 By faith, even though Sarah herself was barren and he was too old, he received the ability to procreate, because he regarded the one who had given the promise to be trustworthy. 11:12 So in fact children were fathered by one man – and this one as good as dead – like the number of stars in the sky and like the innumerable grains of sand on the seashore.
