The exhortation thus regarded suggests the power and duty of faith even in times of disaster and sorrow. But another meaning has often been attached to these words, they have been lifted into another region, the spiritual, and have been supposed to refer to a state of feeling not unknown to devout hearts, in which the religious life is devoid of joy and peace. That is a phase of Christian experience, which meets any one who knows much of the workings of men's hearts, and of his own, when faith is exercised with but little of the light of faith, and the fear of the Lord is cherished with but scant joy in the Lord. Now if it be remembered that such an application of the words is not their original purpose, there can be no harm in using them so. Indeed we may say that, as the words are perfectly general, they include a reference to all darkness of life or soul, however produced, whether it come from the night of sorrow falling on us from without, or from mists and gloom rising like heavy vapours from our own hearts. So considered, the text suggests the one remedy for all gloom and weakness in the spiritual life. Thus, then, we have three different sets of circumstances in which faith is enforced as the source of true strength and our all-embracing duty. In outward sorrow and trial, trust; in inward darkness and sadness, trust; in every stage of Christian progress, trust. Or I. Faith the light in the darkness of the world. II. Faith the light in the darkness of the soul. III. Faith the light in every stage of Christian progress. * * * * * I. Faith our light in the darkness of the world. The mystery and standing problem of the Old Testament is the coexistence of goodness and sorrow, and the mystery still remains, and ever will remain, a fact. It is partially alleviated if we remember that one main purpose of all our sorrows is to lead us to this confidence. 1. The call to faith is the true voice of all our sorrows. It seems easy to trust when all is bright, but really it is just as hard, only we can more easily deceive ourselves, when physical well-being makes us comfortable. We are less conscious of our own emptiness, we mask our poverty from ourselves, we do not seem to need God so much. But sorrow reveals our need to us. Other props are struck away, and it is either collapse or Him. We learn the vanity, the transiency, of all besides. Sorrow reveals God, as the pillar of cloud glowed brighter when the evening fell. Sorrow is meant to awaken the powers that are apt to sleep in prosperity. So the true voice of all our griefs is 'Come up hither.' They call us to trust, as nightfall calls us to light up our lamps. The snow keeps the hidden seeds warm; shepherds burn heather on the hillside that young grass may spring. 2. The call to faith echoes from the voice of the Servant.
