I got it from right here:
Hebrews chapter 11
[13] 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.
[14] For they that say such things declare plainly that they seek a country.
[15] And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned.
[16] 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.
Abraham "died in faith, not having received the promises", which he obviously believed in, "but seeing them afar off", he was "PERSUADED OF THEM, AND EMBRACED THEM, and confessed that" he was a "stranger and pilgrim on the earth" because...wait for it...HE DESIRED A BETTER COUNTRY, THAT IS, AN HEAVENLY" knowing that God "had PREPARED FOR HIM A CITY".
Got it?
Now, tell us, if you would be so kind, what HEAVENLY CITY THAT GOD HAD PREPARED FOR HIM Abraham was looking forward to when he "died in faith" and how he expected entrance into the same.
