Charles H. Spurgeon on Psalms 19:13

Happy souls, who, under a sense of peace through the blood of Jesus, are daily praying to be kept by the grace of the Spirit. Such truly know themselves, see their danger of falling, will not, dare not palliate or lessen the odious nature, and hateful deformity of their sin. They will not give a softer name to sin than it deserves, lest they depreciate the infinite value of that precious blood which Jesus shed to atone its guilt. Far will they be from flattering themselves into a deceitful notion that they are perfect, and have no sin in them. The spirit of truth delivers them from such errors; he teacheth them as poor sinners to look to the Saviour, and to beseech him to "keep back" the headstrong passions, the unruly lusts and evil concupiscences which dwell in their sinful natures. Alas! the most exalted saint, the most established believer, if left to himself, how soon might the blackest crimes, the most "presumptuous sins," get the "dominion" over him! David had woful experience of this for a season. He prays from a heartfelt sense of past misery, and the dread of future danger, and he found the blessing of that covenant-promise: "Sin shall not have dominion over you; for ye are not under the law, but under grace." Romans 6:14. —William Mason, 1719-1791, in "A Spiritual Treasury for the Children of God."
