Charles H. Spurgeon on Psalms 119:136

Rivers of waters run down mine eyes, because they keep not thy law. He wept in sympathy with God to see the holy law despised and broken. He wept in pity for men who were thus drawing down upon themselves the fiery wrath of God. His grief was such that he could scarcely give it vent; his tears were not mere drops of sorrow, but torrents of woe. In this he became like the Lord Jesus, who beheld the city, and wept over it; and like unto Jehovah himself, who hath no pleasure in the death of him that dieth, but that be turn unto him and live. The experience of this verse indicates a great advance upon anything we have had before: the psalm and the Psalmist are both growing. That man is a ripe believer who sorrows because of the sins of others. In Psalms 119:120 his flesh trembled at the presence of God, and here it seems to melt and flow away in floods of tears. None are so affected by heavenly things as those who are much in the study of the word, and are thereby taught the truth and essence of things. Carnal men are afraid of brute force, and weep over losses and crosses; but spiritual men feel a holy fear of the Lord himself, and most of all lament when they see dishonour cast upon his holy name. "Lord, let me weep for nought but sin,

And after none but thee,

And then I would, O that I might!

A constant weeper be."
