After forty years of his life had gone by, Moses could no longer wait to deliver the children of Israel. He had received the highest education, and he had become a man powerful in words and in deeds (Acts 7:22). According to his own estimation, no doubt he thought he was qualified and ready to act on behalf of his people. But God set Moses aside for another forty years, until he was fully prepared according to God’s standard. In this we see the patience of our God. God had to wait until Moses was born. Forty years later Moses was there, and had grown up, but God still had to wait because Moses was so natural. God had to wait because there was the lack of a prepared one.
