Hebrews 11:9-12

It was by faith that he lived like a foreigner in the country God promised to give him. He lived in tents with Isaac and Jacob, who had received that same promise from God. Abraham was waiting for the city that has real foundations—the city planned and built by God. He was too old to have children, and Sarah could not have children. It was by faith that Abraham was made able to become a father, because he trusted God to do what he had promised. This man was so old he was almost dead, but from him came as many descendants as there are stars in the sky. Like the sand on the seashore, they could not be counted.
