Charles H. Spurgeon on Psalms 19:13

"Let them not have dominion over me." Any small sin may get the upper-hand of the sinner and bring him under in time, and after that is once habituated by long custom so as he cannot easily shake off the yoke, neither redeem himself from under the tyranny thereof. We see the experiment of it but too often, and too evidently in our common swearers and drunkards. Yet do such kind of sins, for the most part, grow on by little and little, steal into the throne insensibly, and do not exercise dominion over the enslaved soul till they have got strength by many and multiplied acts. But a presumptuous sin worketh a great alteration in the state of the soul at once, and by one single act advanceth marvelously, weakening the spirit, and giving a mighty advantage to the flesh, even to the hazard of a complete conquest. —Robert Sanderson.
