An intelligent and skillful physician, vigorous, athletic, and courageous, used to pursue his professional duties by day or night without anxiety or apprehension. Often he was desired to use a lantern in his nightly journeyings, but he laughed at the idea of danger, and went his way. One night, walking in some slippery path, he fell; an injury resulted, followed by long months of weariness and pain, and finally ending in his death. It was a sad fall, and all for want of a lamp. Bitterly did he regret his self-confidence when it was too late to remedy the mischief which it had occasioned. There are multitudes to-day who are wandering in darkness and walking in unknown ways. They are full of strength, and hope, and courage; they do not think that /they/ are in danger; though caution is commendable in others. This world is full of darkness; clouds and shadows curtain it on every hand; the glooms of the present, the uncertainties of the future, and the shadowy mysteries of the great Beyond, teach us with emphasis that we have need of light, and light which men can never give us. We may draw wisdom from the experience of the past, but what we /need/ is a knowledge of the future. This knowledge is not attainable through any human intelligence; it must come from Him who dwelleth in light, who is himself the light and life of men, and who sends out his light and his truth to lead and guide the sons of Adam. Of old it was written, "The commandment is a lamp, and the law is a light." The work of the servants of God has been to turn the Gentiles "from darkness to light, and from the power of Satan unto God." It is "the light of the glorious gospel of Christ" which illuminates the darkness of this world; and those who embrace that gospel become the "children of the light," and are "not of the night nor of darkness." Christ was "the true light which lighteth every man that cometh into the world;" and "this is the condemnation, that light has come into the world, and men loved darkness rather than light, because their deeds were evil." Being thus illuminated, and made "light in the Lord," we are to "walk as children of the light;" and walking in the light as Christ is in the light, we have fellowship one with another, and the blood of Jesus
