Is the Old Testament just a bunch of stories and instruction for what we should and shouldn’t do? Or is it one big story compiled of smaller stories, that all make up an unfolding drama of redemption from Genesis to Revelation, in which God reveals hints and pictures that all point to the grand climax of this story: the perfect, law-fulling life, sacrificial death and hope filled resurrection, ascension and return of Christ? I would argue the latter. For instance, the writer of Hebrews says of Moses:
By faith Moses, when he was grown up, refused to be called the son of Pharaoh’s daughter, 25 choosing rather to be mistreated with the people of God than to enjoy the fleeting pleasures of sin. 26 He considered the reproach of Christ greater wealth than the treasures of Egypt, for he was looking to the reward. – Hebrews 11:24-26
