What's evil? The suicidal preference of empty wells over the river of delights flowing from heaven. That's evil!
The battle against evil is not to constantly say "No, no, no. Bad, bad, bad." There's no power in that. The power of the flesh is coming at you, the power of the devil is coming at you, and you're going to [muster] up your willpower and make that the victory? You're not. You're not.
One thing will give you the victory: Faith is the victory that overcomes the world. And faith is a being satisfied in all that God is for us in Jesus Christ. You've got to stoke that engine every morning so that the evils that are clawing at you loose its fangs. You can't have me, I've seen Jesus this morning. Lust, you can't have me. Greed, you can't have me. Fear of man, you can't have me. Bitterness and anger, you can't have me. I've seen Jesus this morning.
