God has heard the cry of the Israelites and has come to send Moses to rescue them. Has Moses been paying much attention to their cry? We are told nothing of his yearnings to save his people. "Who am I?" he asks. "Why have you picked me?"
I've always read this as modesty on Moses' part. But, now I'm thinking that it may be more than modesty. It may be a sincere question, "Why me? Why not someone who has spent years devoted to freedom fighting?" Or, "Why not somebody who doesn't have a steady job and a family to take care of? Don't you know some single, underemployed people who have time for charity work?" [I admit I'm going a little over the top now, but I'm thinking of common current reasons for not doing God's work.]
God responds, "What difference does it make who you are or what you think you are good at? Think about it. I Am the one who is sending you."
