Charles H. Spurgeon on Psalms 52:1

The goodness of God endureth continually. He contrasts the goodness of God with the wealth and might of Doeg, and the foundation of his own confidence as widely different from that of Doeg, his own placed upon the goodness of God, enduring for ever and showing itself effectual. It is as if he had said, The goodness of God to which I trust, is most powerful and the same throughout all time, and in it I shall at all times most surely rejoice that goodness of God, since now it sustains me, so it will exalt me in its own good time; it therefore is, and will be above me. . . . Not without emphasis does he say the goodness la of the strong God, a contrast to Doeg the hero, and the ruinous foundation of his fortune. Hermann Venema.
