Charles H. Spurgeon on Psalms 79:5

"How long, Lord? Wilt thou be angry for ever?" The voice of complaint says not, How long, Lord, shall this wickedness of our enemy endure? How long shall we see this desolation? But, How long, O Lord? Wilt thou be angry for ever? We are admonished, therefore, in this passage, that we should recognize the anger of God against us in all our afflictions, lest as the nations are accustomed, we only accuse the malice of our enemies, and never think of our sins and the divine punishment. It cannot be that he who acknowledges the anger of God that is upon him, should not at the same time acknowledge his fault also, unless he wishes to attribute the iniquity to God of being angry and inflicting stripes upon the undeserving.—Musculus.
