When God calls us to any service or task or duty whatsoever, no supposed personal in-capacity, incompetency, or insufficiency may ever be urged as a reason for not obeying. God never really bids us do a thing we cannot do, and do well, with his help. He would not mock us with an unreasonable requirement. The achieving of impossible commands, of course, is not our business at all. We have nothing whatever to do with the impossible part; that belongs to God. But we have everything to do with the obeying of the command that comes to us. It is not ours to reason, to demur, to urge inability; it is ours promptly, unquestioningly to obey, and then as we go forward God will divide the water or cleave the mountain or roll away the stone. As we approach the obstacle, going in holy obedience, we shall find the way open for our feet.
