Charles H. Spurgeon on Psalms 5:9

If the whole soul be infected with such a desperate disease, what a great and difficult work it is to regenerate, to restore men again to spiritual life and vigour, when every part of them is seized by such a mortal distemper! How great a cure doth the Spirit of God effect in restoring a soul by sanctifying it! To heal but the lungs or the liver, if corrupted, is counted a great cure, though performed but upon one part of thee; but all thy inward parts are very rottenness. "For there is no faithfulness in their mouth; their inward part is very wickedness; their throat is an open sepulchre; they flatter with their tongue." How great a cure is it then to heal thee! Such as is only in the skill and power of God to do. Thomas Goodwin.
