Moses made his decision based on trusting in and believing in a God he could not see but knew that He existed and that He would be the one to deliver the Children of Isreal out of Egypt. Had he been more focused on all the natural things that was afforded him just because of who he was, he would have never been in a position to be the instrument God wanted to us to free his people from bondage. So it is today, in order for us to see, move, and be used by God we must be able to stay in the Spirit so that we will not fulfill the lust of the flesh. God need US, it's time to grow in spiritual things!
