Hebrews 11:13-19

These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth. For they that say such things declare plainly that they seek a country. And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned. But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city. By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son, of whom it was said, That in Isaac shall thy seed be called: accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
