Moses and Aaron
God appeared to Moses and told him he was chosen to lead the Israelites out of slavery in Egypt. Moses was reluctant to undertake this assignment and began raising objections. He began by asking why he had been chosen for the job.
But Moses said to God, “Who am I that I should go to Pharaoh and bring the children of Israel out of Egypt?” (Exodus 3:11)
After God answered him he asked how to respond if the Israelites wanted to know the name of the God who had spoken to him.
Then Moses said to God, “If I come to the people of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” (Exodus 3:13)
God answered his question and then he protested that the Israelites would not believe God had spoken to him and that he was not a good speaker.
Then Moses answered, “But behold, they will not believe me or listen to my voice, for they will say, ‘The LORD did not appear to you.’” (Exodus 4:1)
But Moses said to the LORD, “Oh, my Lord, I am not eloquent, either in the past or since you have spoken to your servant, but I am slow of speech and of tongue.” (Exodus 4:10)
God responded to both of these objections. Moses gave up arguing with God and simply admitted that he didn’t want to do what God wanted.
But he said, “Oh, my Lord, please send someone else.” (Exodus 4:13)
Here is God’s response.
Then the anger of the Lord was kindled against Moses and he said, “Is there not Aaron, your brother, the Levite? I know that he can speak well. Behold, he is coming out to meet you, and when he sees you, he will be glad in his heart. You shall speak to him and put the words in his mouth, and I will be with your mouth and with his mouth and will teach you both what to do.He shall speak for you to the people, and he shall be your mouth, and you shall be as God to him.” (Exodus 4:14-16)
God told Moses that his brother Aaron would be the one who actually spoke God’s message. With this assurance Moses consented to obey God’s command.
This account shows us that when God chooses someone for a task he will also equip him to carry out that task. But the fact that Aaron’s help was needed illustrates an important truth.
For the law was given through Moses; grace and truth came through Jesus Christ. (John 1:17)
Moses represents the law. The law shows how God wants us to live but it doesn’t empower us to live that way. For this reason Moses alone could not have given the Israelites a message of liberation.
Aaron would become the beginning of a priesthood that would offer sacrifices to atone for the sins others committed. Grace came through Jesus Christ but it would be foreshadowed through Aaron.
The message of the Bible includes both law and grace. It is God’s grace that provides forgiveness but the law is necessary to show people that they need this grace.
