12. So from one man, though he was physically as good as dead, there have sprung descendants whose number is as the stars of heaven and as countless as the innumerable sands on the seashore. [Gen. 15:5, 6; 22:17; 32:12.]
13. These people all died controlled and sustained by their faith, but not having received the tangible fulfillment of [God's] promises, only having seen it and greeted it from a great distance by faith, and all the while acknowledging and confessing that they were strangers and temporary residents and exiles upon the earth. [Gen. 23:4; Ps. 39:12.]
14. Now those people who talk as they did show plainly that they are in search of a fatherland (their own country).
15. If they had been thinking with [homesick] remembrance of that country from which they were emigrants, they would have found constant opportunity to return to it.
16. But the truth is that they were yearning for and aspiring to a better and more desirable country, that is, a heavenly [one]. For that reason God is not ashamed to be called their God [even to be surnamed their God–the God of Abraham, Isaac, and Jacob], for He has prepared a city for them. [Exod. 3:6, 15; 4:5.]
17. By faith Abraham, when he was put to the test [while the testing of his faith was still in progress], had already brought Isaac for an offering; he who had gladly received and welcomed [God's] promises was ready to sacrifice his only son, [Gen. 22:1-10.]
18. Of whom it was said, Through Isaac shall your descendants be reckoned. [Gen. 21:12.]
