Charles H. Spurgeon on Psalms 50:21

Thou thoughtest that I was altogether such an one as thyself. Such is the blindness and corruption of our nature, that we have very deformed and misshapen thoughts of him, till with the eye of faith we see his face in the glass of the word; and therefore Mr. Perkins affirms, that all men who ever came of Adam (Christ alone excepted) are by nature atheists; because at the same time that they acknowledge God, they deny his power, presence, and justice, and allow him to be only what pleaseth themselves. Indeed, it is natural for every man to desire to accommodate his lusts with a conception of God as may be most favourable to and suit best with them. God charges some for this: Thou thoughtest that I was altogether such an one as thyself. Sinners do with God as the Ethiopians do with angels, whom they picture with black faces that they may be like themselves. William Gurnall.
