If God were as smart as we are, He would certainly have begun everything better than otherwise happened. For here He takes for this difficult, high work one who cannot speak well, as Moses himself confessed [Exodus 4:10-13]. But God says to him: Go and carry it out. That is the same as if He told a blind man that he should see well, a lame man that he should run well, a mute man that he should speak well. Could God not find someone else to use for this work?
But it is written so that we may learn God's attitude. What counts in the eyes of the world, He does not regard. He rejects and discards what others grab for. He throws away what others love and exalt. And what the devil does not want, that He accepts. He gives Moses a correct answer and says: You are a clever and fine fellow. That is nettling, as if He ment to say: Do you think that I do not know that you stutter, as if I did not hear it?--
So it seems to us, for we always want to outdo God in His works, as if we were the very first to see these faults, shortcomings, and frailties, but God does not see them."
--M.Luther, quoted in Pastoral Theology by C.F.W. Walther
"If God were as smart as we are...." Man, I get such a kick out of Luther!
