Self-confidence is not the temper which God uses for His instruments. He works with 'bruised reeds,' and breathes His strength into them. It is when a man says 'I can do nothing,' that he is fit for God to employ. 'When I am weak, then I am strong.' Moses remembered enough of Egypt to know that it was no slight peril to front Pharaoh, and enough of Israel not to be particularly eager to have the task of leading them. But mark that there is no refusal of the charge, though there is profound consciousness of inadequacy. If we have reason to believe that any duty, great or small, is laid on us by God, it is wholesome that we should drive home to ourselves our own weakness, but not that we should try to shuffle out of the duty because we are weak. Moses' answer was more of a prayer for help than of a remonstrance, and it was answered accordingly. God deals very gently with conscious weakness. 'Certainly I will be with thee.' Moses' estimate of himself is quite correct, and it is the condition of his obtaining God's help. If he had been self-confident, he would have had no longing for, and no promise of, God's presence. In all our little tasks we may have the same assurance, and, whenever we feel that they are too great for us, the strength of that promise may be ours. God sends no man on errands which He does not give him power to do. So Moses had not to calculate the difference between his feebleness and the strength of a kingdom. Such arithmetic left out one element, which made all the difference in the sum total. 'Pharaoh _versus_ Moses' did not look a very hopeful cause, but 'Pharaoh _versus_ Moses and Another'--that other being God--was a very different matter. God and I are always stronger than any antagonists. It was needless to discuss whether Moses was able to cope with the king. That was not the right way of putting the problem. The right way was, Is God able to do it? The sign given to Moses is at first sight singular, inasmuch as it requires faith, and can only be a confirmation of his mission when that mission is well accomplished. But there was a help to present faith even in it, for the very sacredness of the spot hallowed now by the burning bush was a kind of external sign of the promise.
