Some Christians take the path of stoicism in the fight against sensuality. It doesn't work. It's not biblical. It is hopelessly weak and ineffective. And the reason it fails is that the power of sin comes from its promise of pleasure and is meant to be defeated by the ... promise of superior pleasure in God, not by raw human willpower. Willpower religion, when it succeeds, gets glory for the will. It produces legalists, not lovers.
