There is no disease, no addiction, no demon, no bad habit, no fault, no vice, no weakness, no temper, no moodiness, no pride, no self-pity, no strife, no jealousy, no perversion, no greed, no laziness that Christ will not overcome as the enemy of his honor.

And the encouragement in that promise is that when you set yourself to do battle with the enemies of your faith and your holiness, you will not fight alone.

- John Piper, He Must Reign
