28 Now when the Lord spoke to Moses in Egypt, 29 he said to him, “I am the Lord. Tell Pharaoh king of Egypt everything I tell you.”
30 But Moses said to the Lord, “Since I speak with faltering lips, why would Pharaoh listen to me?” Exodus 6:28-30
Why does God choose some people and ignore others? Moses is absolutely correct. Certainly the Lord could have chosen someone more eloquent in speech and manners to talk with Pharaoh. But Moses’ unique upbringing gave him a leg up on any competitors. And besides, as we’ve stated many times, God chooses the weak to prove how strong He is. If you could do it on your own, you could also easily take the credit for doing it on your own.
We get a glimpse into Moses’ thinking but would rarely want to reveal similar thinking on our part. We might voice those fears to God, but never to several billion people who would eventually read our words.
As an aside, since Moses wrote the first five books of our Bible, he made himself even more vulnerable by writing down his failed conversation/argument with God.
To answer Moses’ question, though, Pharaoh should not listen to Moses. He’s the supreme ruler of Egypt. Men live and die at his command. They tremble in fear as he passes by. They cower in his presence.
But Moses was commanded by the Almighty God to approach him and make unique demands. The God of the Universe would right there with him, encouraging him, telling him the exact words to say, and leading him away safely. In Moses’ own strength, he should stay home and play with his grandchildren. In the strength and power of Almighty God he could do the same with a dozen kings and come out unscathed.
