Hebrews 11:13 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, 14 for people who speak in this way make it clear that they are seeking a homeland. 15 If they had been thinking of the land that they had left behind, they would have had opportunity to return. 16 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.
