Every one of them is gone back: they are altogether become filthy; there is none that doeth good, no, not one.

Matthew Henry's Concise Commentary

53:1-6 The corruption of man by nature. - This psalm is almost the same as the 14th. The scope of it is to convince us of our sins. God, by the psalmist, here shows us how bad we are, and proves this by his own certain knowledge. He speaks terror to persecutors, the worst of sinners. He speaks encouragement to God's persecuted people. How comes it that men are so bad? Because there is no fear of God before their eyes. Men's bad practices flow from their bad principles; if they profess to know God, yet in works, because in thoughts, they deny him. See the folly of sin; he is a fool, in the account of God, whose judgment we are sure is right, that harbours such corrupt thoughts. And see the fruit of sin; to what it brings men, when their hearts are hardened through the deceitfulness of sin. See also the faith of the saints, and their hope and power as to the cure of this great evil. There will come a Saviour, a great salvation, a salvation from sin. God will save his church from its enemies. He will save all believers from their own sins, that they may not be led captive by them, which will be everlasting joy to them. From this work the Redeemer had his name JESUS, for he shall save his people from their sins, Mt 1:21.
