- God will Teach
Exodus 4:12 Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say.
This is a promise given directly and only to Moses: the Lord will teach Moses what to say. This is not a promise for us, but in the NT Jesus says the Holy Spirit will “teach you all things and bring to remembrance all that I have said to you.” This promise is for us. We can believe the promise that the Lord God, the Holy Spirit, who lives within us, will teach us what to say. Trust God to give you thoughts to think and words to say at the appropriate time and place when needed.
We do not even know the effect of our witness and the words we speak when we give a reason for the hope within. All who believe in Jesus can count on the leading and guiding of the Spirit, especially when we witness to Christ.
The Lord gives this promise to Moses because he did not feel worthy or good enough to confront Pharaoh and speak for the Lord. God gives to Moses and to us the promise that He will do the speaking when we surrender our lips, mouth and tongue to the Lord so that the Spirit can use them. God will not let us use the excuse that we are inadequate. It’s His work anyway; it is not dependent on our eloquence. Moses objected to God’s call four times, and each time God said to him, “I’m doing this, not you. I just need a willing vessel. You will do this.”
We certainly don’t know everything, but His Promise encourages us to trust the Lord to do and say what He wants us to do and to say. He may sometimes even want to use plain people, like Moses and you and I.
