Charles H. Spurgeon on Psalms 42:7

Deep calleth unto deep at the noise of thy waterspouts. Thy severe dealings with me seem to excite all creation to attack me; heaven, and earth, and hell, call to each other, stirring each other up in dreadful conspiracy against my peace. As in a waterspout, the deeps above and below clasp hands, so it seemed to David that heaven and earth united to create a tempest around him. His woes were incessant and overwhelming. Billow followed billow, one sea echoed the roaring of another; bodily pain aroused mental fear, Satanic suggestions chimed in with mistrustful forebodings, outward tribulation thundered in awful harmony with inward anguish: his soul seemed drowned as in a universal deluge of trouble, over whose waves the providence of the Lord moved as a watery pillar, in dreadful majesty inspiring the utmost terror. As for the afflicted one he was like a lonely bark around which the fury of a storm is bursting, or a mariner floating on a mast, almost every moment submerged. All thy waves and thy billows are gone over me. David thought that every trouble in the world had met in him, but he exaggerated, for all the breaking waves of Jehovah have passed over none but the Lord Jesus; there are griefs to which he makes his children strangers for his love's sake. Sorrow naturally states its case forcibly; the mercy is that the Lord after all hath not dealt with us according to our fears. Yet what a plight to be in! Atlantic rollers sweeping in ceaseless succession over one's head, waterspouts coming nearer and nearer, and all the ocean in uproar around the weary swimmer; most of the heirs of heaven can realise the description, for they have experienced the like. This is a deep experience unknown to babes in grace, but common enough to such as do business on great waters of affliction: to such it is some comfort to remember that the waves and billows are the Lord's, "thy waves and thy billows, "says David, they are all sent, and directed by him, and achieve his designs, and the child of God knowing this, is the more resigned.
