Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry. — Colossians 3:5
We need to be intimately acquainted with the ways, wiles, methods, advantages, and occasions in which lust has victory. This is the way that men deal with their enemies. They search out their plans, ponder their goals, and consider how and by what means they have prevailed in the past. Then, they can be defeated.
If you do not utilize this great strategy, your warfare is very primitive. We need to know how sin uses occasions, opportunities, and temptations to gain advantage.
We need to trace this serpent in all of its windings, and to recognize its most secret tricks: 'This is your usual way and course; I know what you aim at.' Even when one thinks that a lust is dead because it is quiet, we must labour to give it new wounds and new blows everyday.
When the heart recognizes at any time sin and temptation at work, seducing and forming sinful imaginations to get you to fulfill its lusts, the heart must immediately see it for what it is, bring it to the law of God and love of Christ, condemn it, and follow it to execute it to the uttermost.
