If there was one thing that a Christian must do, what comes to your mind? The preacher suggests that the killing of sin is the answer. Considering the theme of the 2026 men's retreat (which was "The Man of Courage"), the courageous man kills his sin. Think of the world that you live in and how it celebrates and worships its sin. The man of courage kills his sin in an adversial way in comparison to the world. Using King Josiah of Judah, the preacher paints a picture using him as a sin killer in the land of Israel, which at the time was living in Baal worship. In this current day, will you stand against the wicked tide of the world and kill your sin? You can be assured that you will be mocked, laughed at, and hated. The man of courage willingly endures these things to kill his sin and be conformed all the more to the image of Christ.
