This is a one point post. The law is right and true, but the keeping of the law and the covenant of the law came by faith. The fleshpots of Egypt did not merely have to be rejected: they were destroyed by plague. The remaining elite did not survive the red sea, and the historians disavowed the Hebrew.
But the law came after faith. Not before.
23 By faith Moses, when he was born, was hidden for three months by his parents, because they saw that the child was beautiful, and they were not afraid of the king's edict. 24 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. 27 By faith he left Egypt, not being afraid of the anger of the king, for he endured as seeing him who is invisible. 28 By faith he kept the Passover and sprinkled the blood, so that the Destroyer of the firstborn might not touch them.
