In Ex. 4:11 God declares to Moses that He made Mose’s mouth.
So the LORD said to him, “Who has made man’s mouth? Or who makes the mute, the deaf, the seeing, or the blind? Have not I, the LORD? Now therefore, go, and I will be with your mouth and teach you what you shall say.”
Moses cried out to God, complaining to Him that he would be ineffective with Pharaoh. He did not have the words at hand to make a difference in Israel’s future.
How fortunate that Moses recognized his shortcomings, that he was verbally challenged. One cannot speak for God when their own thoughts control their speech. To speak for God, Moses had to draw closer to Him. The closer he came to God, the less he spoke of his self interests. He quickly gained the confidence to speak for God.
God makes a power packed promise to be with Mose’s mouth and to train his mouth. Is there a need for God to train my mouth as well? I think so. I can’t think of a better speech coach than God. He can remove my fear of speaking to powerful people. He can tame my nervousness when I meet someone new. He can cause my mind to have amazing thoughts and then translate those thoughts into words that will offer courage and help to someone who needs it.
Words are powerful. They are the ingredients for change. Moses spoke clearly to Pharaoh when he told him that God wanted Pharaoh to let His people go. The ruler did not take Moses seriously at first. The words seem to have fallen on deaf ears. Sometimes God wants us to speak for Him, even when it looks like our words are ineffective.
The writer of this Psalm also wanted God to train or inspire his mouth. Let my mouth be filled with thy praise and with thy honour all the day. Psalm 71:8
And finally this well know Psalm, Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer. Psalm 19:14
Beautiful words, God honoring words come from the heart and mouth of those who are close to God, those who receive training and coaching from God.
