It is time for us Christians to face up to our responsibility for holiness. Too often we say we are "defeated" by this or that sin. No, we are not defeated; we are simply disobedient! It might be well if we stopped using the terms "victory" and "defeat" to describe our progress in holiness. Rather we should use the terms "obedience" and "disobedience."
When I say I am defeated by some sin, I am unconsciously slipping out from under my responsibility. I am saying something outside of me has defeated me. But when I say I am disobedient, that places the responsibility for my sin squarely on me. We may, in fact, be defeated, but the reason we are defeated is because we have chosen to disobey.
-Jerry Bridges, 'The Pursuit of Holiness'
