Faith is called upon, and that right often, to wait in patience before God, and is prepared for God's seeming delays in answering prayer. Faith does not grow disheartened because prayer is not immediately honored; it takes God at his Word, and lets him take what time he chooses in fulfilling his purposes, and in carrying on his work. There is bound to be much delay and long days of waiting for true faith, but faith accepts the conditions — knows there will be delays in answering prayer, and regards such delays as times of testing, in the which, it is privileged to show its mettle, and the stern stuff of which it is made.
