Moses pleaded with God to let him out of his mission. After all, he was not a good speaker and would probably embarrass both himself and God.
But God looked at Moses’ problem quite differently. All Moses needed was some help, and who better than God to help him say and do the right things? God made his mouth and would give him the words to say.
It is easy for us to focus on our weaknesses, but if God asks us to do something, then he will help us get the job done. If the job involves some of our weak areas, then we can trust that he will provide words, strength, courage, and ability where needed.
