Charles H. Spurgeon on Psalms 107:4

Wandered in the wilderness, etc. He has lost his way. When he was in the world, he had no difficulties; the path was so broad that he could not mistake it. But when the work of divine grace begins in a sinner's heart, he loses his way. He cannot find his way into the world; God has driven him out of it, as he drove Lot out of Sodom. He cannot find his way to heaven; because he at present lacks those clear testimonies, those bright manifestations whereby alone he can see his path. This is his experience then, that he has lost his way; having turned his back upon the world; and yet unable to realise those enjoyments in his soul that would make heaven his home. He has so lost his way, that whether he turns to the right hand or the left, he has no plain land marks to show him the path in which his soul longs to go. We need not stray from the text to find where the wanderer is. "They wandered in the wilderness." The wilderness is a type and figure of what this life is to the Lord's people. There is nothing that grows in it fit for their food or nourishment. In it the fiery flying serpents —sin and Satan —are perpetually biting and stinging them: and there is nothing in it that can give them any sweet and solid rest. The barren sands of carnality below, and the burning sun of temptation above, alike deny them food and shelter. But there is a word added which throws a further light upon the character of the wilderness. "They wandered in the wilderness, in a solitary way; "a way not tracked; a path in which each has to walk alone; a road where no company cheers him, and without landmarks to direct his course. This is a mark peculiar to the child of God —that the path by which he travels is, in his own feelings, a solitary way. This much increases his exercises, that they appear peculiar to himself. His perplexities are such as he cannot believe any living soul is exercised with; the fiery darts which are cast into his mind by the Wicked One are such as he thinks no child of God has ever experienced; the darkness of his soul, the unbelief and infidelity of his heart, and the workings of his powerful corruptions, are such as he supposes none ever knew but himself. It is this walking "in a solitary way", that makes the path of trial and temptation so painful to God's family. —J.C. Philpot (1802-1869), in a Sermon entitled "The Houseless Wanderer."
