Moses said, “Please, Lord, send someone else.” Exodus 4:13
Chapters 3 and 4 are some of the most relatable chapters in Exodus and maybe for you too.
Moses. The Moses. The great prophet and leader. Moses seems to be struggling with some type of imposter syndrome. God approached him in chapter 3 through a burning bush and called him to lead the Hebrews out of Egyptian slavery. God had been preparing him for this moment since he was taken into Pharaoh's home as a baby. Yet, Moses does not feel qualified. He says, "Who am I that I should go to Pharaoh and that I should bring the Israelites out of Egypt?” (Exodus 3:11). Then he proceeded to try and get out of this calling by every means available. It's actually a comical scene. No matter how God comforted and encouraged him, he came up with a new excuse for why he couldn't!
It reminds me of a friend I had when I was 10 or 11. He was not a Christian and didn't have much use for church things, but I would often invite him to church. I always got some excuse for why he couldn't make it, but my favorite, by far, is when he unironically told me that he couldn't come to church because he had to watch his orange juice thaw. If Moses could have had that excuse, he may have used it.
Moses's final excuse was that he had a speech impediment and couldn't go. No one would take him seriously. God had had enough. The text tells us, "the LORD’s anger burned against Moses..." Of course, God knew Moses's disability, and that did not change one thing about God's call on Moses's life. God was always going to provide all Moses needed to complete the plan of God. Even if it meant giving him a new mouth.
God reminded Moses, "Isn’t Aaron the Levite your brother? I know that he can speak well... He will speak to the people for you. He will serve as a mouth for you..."
God was always going to be with Moses. But God understood that sometimes we need a faithful brother or sister to literally lock arms with and complete his will. God may call you to do something extraordinary, and he will be with you through it all, but he has also provided a spiritual family to walk alongside you.
If God is calling you to do something hard, terrifying, and extraordinary, he will probably not call you to do it alone. If you struggle to act on his calling, you should talk to a trusted follower of Christ. Do not keep whatever God has called you a secret, because if you do, that is a good way to never obey God. Tell someone, seek counsel, support, and help. God has given you everything you need for life and godliness, including your spiritual family.
The greatest thing any of us can do is be obedient to God. So do not let some excuses, big or small, stop you from doing that.
