Where does I begin?  I read Crazy Love by Francis Chan as well.  His sophomore book was well worth the read.  Chan takes aim at the Holy Spirt, or lack there of in our modern Christian lives and Church.  He does a great job speaking to the various denominations and asks some really tough questions; Questions that made me consider just how important the spirit is to my daily life.  As most other Christians, this is not anything new, but it was refreshing to stop and just meditate on who the spirit is and how he is leading me.  If you have the time pick this gem up, you will not be disappointed.
