We tell our young men in the College that they must prove that they have not to go, or else their duty is clear. If some of the men of Israel had said to Joshua, “We cannot go to Ai,” Joshua would have replied, “You must prove that you cannot go or you may not be excused.” All other things being equal ministers should take it for granted that it is their duty to invade new territory unless they can prove to the contrary.
I remember one who spoke on the missionary question one day saying, “The great question is not ‘Will not the heathen be saved if we do not send them the gospel?’ but ‘are we saved ourselves if we do not send them the gospel?’ ”
