Acts 7:24-25

Moses learned all the wisdom of Egypt, but he also knew a very great deal about the history of his people. He knew that the 400 years were almost up. He knew that the fourth generation was then living in Egypt. He could add. He could subtract. He could look around. He could understand. He knew that he was an Israelite. He knew who his ancestry was. He knew that he was directly descended from Jacob, who was descended from Abraham. He knew what his lineage was. And it must have been communicated to him in some way that he was going to be the one through whom God was going to deliver His people because the time had come. The question was: would he believe it? Would he trust it? What would he do about it? Would he have enough faith to turn his back on those things that could have been such a powerful pull—all of those things that he could see with his eyes?

The word "supposed" means "reckon," "add it up," "put the pieces together." He reasoned from the evidence he heard from God and he thought that they would reason too. It must have been general knowledge that Moses was the man. Moses was the deliverer. But they did not have faith in it. Moses knew that God had a people. He knew Israel, though in bondage, was that people. He had heard of the things to come—that Israel was to be delivered. He heard the things of Christ, according to Hebrews 11. I do not know all that God communicated to Moses, but I do know that God set before the eyes of his mind what His will and purpose was for him.
