And Moses said unto God, Who am I, that I should go unto Pharaoh?
Moses was questioning God’s wisdom in sending him to rescue the children of Israel. Perhaps he was thinking back to the time when he had killed one of the taskmasters to protect an Israelite. Maybe he felt ashamed now. Don’t look back. Leave the confessed past to God. Don’t have confidence in the flesh, but lean in confidence on God. Enjoy the fact that God loves you. And when He calls you to do something for Him, let Him use you in whatever way He chooses.
