God was calling Moses to something big, something very special, but, still, Moses had his doubts: “But the people will not believe me.”
How did God respond to Moses’ doubts? Did he dismiss him, and start looking for somebody else? No! What did he do? He continued to speak to Moses. To doubting Moses, God spoke words of encouragement: “If they will not believe that the Lord, the God of their fathers, has appeared to you, they may believe signs, and then they will heed your voice.”
How did Moses respond to God’s words of encouragement? He continued to question the call of God: “Oh, my Lord, I am not eloquent. I am slow of speech and tongue.” What are we to make of this? Is it just self-doubt? or Is it going beyond that? Is it moving from self-doubt to doubting God’s power to fulfil his purpose through Moses?
Again, God says to Moses, ‘I am calling you’: “Now go, I will teach you what you shall speak.” Again, Moses resists the call of God. He says, “oh, my Lord, send, I pray, some other person.”
How did God react to this?: “Then the anger of the Lord was kindled against Moses.” Did it mean that God was about to give up on Moses? No! It didn’t mean that. God said that Aaron would help Moses. It is important to understand that Aaron would never be any more than Moses’ helper: “Aaron, your brother, can speak… You shall speak to him and put the words in his mouth. I will be with you and teach you. He shall speak for you to the people; he shall be a mouth and you shall be to him as God.”
Getting the people of Israel out of Egypt was not something that could be achieved by Moses. It was the work of God. In the final plague, we catch a glimpse of something more than the deliverance of the people of Israel from their bondage in the land of Egypt. We catch a glimpse of Jesus Christ, “the Lamb of God who takes away the sin of the world” (John 1:29). We catch a glimpse of Jesus, our Saviour, and we give thanks to God with great joy.
