Who is this that cometh out of the wilderness like pillars of smoke..? – Song of Songs 3:6

When great personages traveled in their palanquins, and more especially on marriage processions, they were attended by a number of persons who, at night, carried high up in the air burning cressets which gave forth a blaze of light. Sometimes these lights were simply torches carried in the hands of running footmen; at other times they were a sort of iron basket lifted high into the air, upon poles, from which went up a pillar of smoke and flame. Our text says, “Who is this that cometh out of the wilderness like pillars of smoke?” a beautiful illustration of the fact that wherever Christ and His cause are carried, light is a sure accompaniment. Into whatsoever region the gospel may journey, her every herald is a flash of light, her every minister a flaming fire. God maketh His Churches the golden candlesticks, and saith unto His children “Ye are the lights of the world,” is certainly as ever God said, “Let there be light,” and there was light over the old creation, so does He say, whenever His Church advances, “Let there be light” and there is light. Dens of darkness, where the bats of superstition had folded their wings and hung themselves up for perpetual ease, have been disturbed by the glare of these divine flambeaux; the innermost caverns of superstition and sin, once black with a darkness which might be felt, have been visited with a light above the brightness of the sun. “The people which sat in darkness have seen a great light, and to them which sat in the region and shadow of death light has sprung up.” Thus, saith the Lord unto the nation where His kingdom cometh, “Arise, shine, for thy light is come, and the glory of the Lord hath risen upon thee!” Bear ye the Church of Christ to the South Seas; carry Christ and His Spouse in His palanquin to the Caffre, the Hottentot, or the Esquimaux, and everywhere the night of death is ended, and the morning with its glorious dawn has come. High lift your lamps, ye servants of our Lord. High lift up the cross of the Redeemer; for in Him is light, and the light in the life of men. ~ C.H. Spurgeon
