Heb 11:39 And these all, having obtained a good report through faith, received not the promise:
Moses suffered for the sake of the Christ who was to come, and although he could not see Christ, he endured it as if seeing Christ. (Heb 11:24-27)
Heb 11:24 By faith Moses, when he was come to years, refused to be called the son of Pharaoh's daughter; 25 Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season; 26 Esteeming the reproach of Christ greater riches than the treasures in Egypt: for he had respect unto the recompence of the reward. 27 By faith he forsook Egypt, not fearing the wrath of the king: for he endured, as seeing him who is invisible.

The promise of descendants that God made to Abraham is Christ. (Gal 3:16)
Gal 3:16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
When Isaac was born, Abraham rejoiced at the thought of Christ, who would come as the descendant of Isaac. (Jn 8:56)
