If you think yourself to be free of sin, that is because you have stopped fighting it. An enemy ceases to be an enemy when you start to call him your friend. Sin is a relentlessly crafty opponent—the moment you sheathe your blade, it will slit your throat. If you are regularly convicted by God’s word and consistently in prayer, then you will never lack brokenness over your own sin. The man who is perpetually confronted with the holiness of God is well aware of his own shortcomings. If you think you have won the fight, then you have already surrendered. If you think you have repented enough, then perhaps you have not repented at all.
