Mike, thanks for the thoughts and resources on Proverbs.  I'm preaching through the first nine chapters now and loving it! 

I will say, though, I've found it at times more difficult to get to Christ in Proverbs than I have in any other literature.  The difficulty, for me, at least, is that so muc of the theology of Proverbs is implicit and the nature of the literature suggests moralism rather than gospel.  But fighting to think through that in ways faithful to the text has been really, really helpful.  In my own soul, I've been discovering more roundedness and depth to the Christian life as I've worked through those issues.  Not sure my preaching shows that, but the preacher has been stretched and taught.

I'd ditto your suggested resources.  Although, I'd have to say Bridges is my favorite.  I'd also recommend Mark's sermons on the first nine chapters.  I remember those being really powerful.

Enjoy Proverbs when you dig into it!  I know I have!
