Luke 11:36

If thy whole body therefore be full of light, having no part dark, the whole shall be full of light, as when the bright shining of a candle doth give thee light.

These proverbial, parabolic sayings of the Lord were favorite remarks of His when He wanted to drive home the great truth of the necessity of harmony between profession and practice of Christian morality. To light a lamp or a light of any kind, and then to place it into a cellar or vault or under a measure, where it cannot be seen and cannot serve as a guide for him that comes into the house, is foolish; for the purpose of the light is not realized. But equally foolish it is for a person professing faith to give no evidence of that faith in outward visible deeds. If there were any present on that day that had gained the conviction of His Messiahship, they should come out boldly for Him and stand up before the whole world. What disastrous results follow the method of being convinced in the heart and yet not daring to confess Christ openly, He shows by a comparison. If the eye of the body, which is its light, is single, healthy, properly fitted for its work, then it severs as the instrument for conveying light to the whole body; but if the eye is evil, unhealthy, not in proper condition, it cannot serve its purpose; and the person possessing such an eye is in darkness though he stand in a flood of sunlight. If then, the light in any person "be darkness, if what he considered to be light be the opposite, then the double darkness of such a person will be appalling. But if the whole body be in bright light and no part in darkness, then the brightness will be like that of lightning. The eye of a Christian is his Christian understanding; it enables the believer to walk in the light of God's Word, makes him ready for every good work. When the light of Christ dwells fully in the heart, it extends its influence to every thought, word, and action, and directs its possessor how he is to comport himself in all places and circumstances. "It is of the utmost importance to have the soul properly influenced by the wisdom that comes down from above. The doctrine that is contrary to the Gospel may say, Ignorance is the mother of devotion; but Christ shows that there can be no devotion without heavenly light. Ignorance is the mother of superstition; but with this the heavenly light has nothing to do."
