“ I spoke of an Army on the point of entering an enemy's territories. Answering the question as to the cause of delay: 'Waiting for supplies.' The answer might also have been: 'Waiting for instructions, 'Waiting for orders.' If the last dispatch had not been received, with the final orders of the commander in chief, the army dared not move. Even so in the Christian life - as deep as the need of waiting for supplies is that of waiting for instructions. ”
