My comment on this post:
As I've had opportunity to stress in some radio interviews, that's in part what the book is about. A lot of the problems we see are results of incomplete (or nonexistent) conversions. Conversion is the result of the clash of two warring worldviews and the victory of God's over ours. When you see someone who still assumes he basically has it all together, but will allow God to make suggestions here and there, you see an incomplete conversion.
Let me hasten to add that we're all at our best "incompletely converted" - but the answer is to go back to basics over and over and over again, always willing to suspect our hearts in the light of God's word.
