I love the story of Moses. He’s one of my Bible favorites. He was given a very challenging task by God and when God instructed Moses to be His spokesperson, Moses responded with his inadequancies. Has God ever asked you to do something and you responded with fear or all the reasons you couldn’t do it? I have. Let’s first look at some scripture. 

God at this point in Exodus 4 has already shown Moses His power. Go back and read Exodus 3 and 4. We are picking up at Exodus 4:10-17.

Then Moses said to the Lord, “Please, Lord, I am not a man of words (eloquent, fluent), neither before nor since You have spoken to Your servant; for I am slow of speech and tongue.” The Lord said to him, “Who has made man’s mouth? Or who makes the mute or the deaf, or the seeing or the blind? Is it not I, the Lord? Now then go, and I, even I, will be with your mouth, and will teach you what you shall say.” But he said, “Please my Lord, send the message [of rescue to Israel] by [someone else,] whomever else You will [choose].”

Then the anger of the Lord was kindled and burned against Moses; He said, “Is there not your brother, Aaron the Levite? I know that he speaks fluently. Also, he is coming out to meet you, and when he sees you, he will be overjoyed. You must speak to him and put the words in his mouth; I, even I, will be with your mouth and with his mouth, and I will teach you what you are to do. Moreover, he shall speak for you to the people; he will act as a mouthpiece for you, and you will be as God to him [telling him what I say to you]. You shall take in your hand this staff, with which you shall perform the signs [the miracles which prove I sent you].”

Moses was human just like us. Rejection doesn’t feel great. Being teased or ridiculed for a weakness doesn’t feel great either. In his shoes I may have thought the same thing, “Who am I to go speak for God?” I actually have had some interesting experiences with this. 
God tells us to find our identity in Him not our gifts, talents, eloquence, knowledge, or performance. Even if we are the best at what we do, we pale in comparison to God. Not even close…to matching His perfection. It’s not about us, it’s about Him.
