The audio book is on my iPod and I've been listening to it on my travels.   I know I have a paper copy somewhere, but I can't put my hands on it right now.

There was something that resonated with me.

Repentance is not "oops, sorry".  Lewis said something to the effect that repentance is a turning - an "unlearning" of the bad behavior that has been learned.

(there is a difference between "sin" and "sins" that I may get into later)

But in order to repent, you have to have a part of "good" inside you that wants to unlearn the behavior.  That part of you is already good - already turned.

Only a good man can repent.  Only a bad man needs to.

Only a perfect man can repent perfectly - and the perfect man doesn't need to.

The bad man must repent and cannot.

Lewis was not Reformed by any stretch of the imagination, but what I can apply here is "regeneration".  We are all affected by "total depravity" - every part of us is touched by Adam's sin.  We are sinners who sin and we all are in need of repentance.

Through the regeneration of the Holy Spirit, we are enabled to repent, however imperfectly.  It is only through the act of the Holy Spirit who calls that we are able to turn to him.

Perfect repentance?  Only God is perfect and only Immanuel, God With Us, is our perfection.

I am a bad person.  There are things that I don't know how to repent of!  I can only trust Christ to cover that sin.,
