C.S. Lewis on Personal Devotion

I particulalry like the part about the pipe and pencil at the end.  My pipe and personal journal are two of my favorite things.  And I tend to like the meat of a good doctrinal book to a devotional book more often than not. 

"For my own part I tend to find the doctrinal books often more helpful in devotion than the devotional books, and I rather suspect that the same experience may await many others. I believe that many who find that "nothing happens" when they sit down, or kneel down, to a book of devotion, would find that the heart sings unbidden while they are working their way through a tough bit of theology with a pipe in their teeth and a pencil in their hand."  - CSL
