Sin should be exceedingly bitter to our soul

Mt 26:75 And Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly

I heard, at Boulogne, the story of a Frenchman who had been drinking heavily, and who threw himself into the harbor. Some sailors plunged in, and rescued him. The man was on the deck of a ship, and in a minute he broke away from his keepers, and jumped in again. It was not pleasant to be trying to save a madman again and again, yet they did get him out, and took him down below; but he rushed on deck, and jumped in a third time. A man there said,” You leave him to me.” So he jumped overboard, and seized hold of him, put his head under the water, and held him there; when he managed to get his head up again, his rescuer gave him another ducking, and then another, till he just about filled him up with water. He said to himself, “I will sicken him of it, so that he will never jump in here again.” He just diluted the eau-de-vie the man had taken, and then he dragged him on board ship, and there was no fear of his jumping overboard any more. And I believe that, sometimes, the Lord acts like that with men. He did so with me; he made sin to be exceedingly bitter to my soul, till I loathed it; and it has often given me a trembling even to think of those sins that then were pleasurable to me. It is a blessed thing to be plucked out of the water, and saved once for all, but a little of that sailor’s style of sousing the drunkard, a little of those terrors and alarms that some of us felt, is not lost; and when the Lord thus deals with sinners, it is with the design that they may never want to go back to those sins any more. They have had their full of them, and henceforth they will keep clear of them. It may be that the Almighty vexed some of you for this cause, that you might thenceforth hate sin with a perfect hatred.
