Hebrews 11:17 Meaning

15And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned.

16But 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.

17By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,

18Of whom it was said, That in Isaac shall thy seed be called:

19Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
