here is John Piper talking about how practically to develop a passion for prayer.

what he says about the stories is just so true. I read a book about George Mueller in high school and it has had to biggest impact on my prayer life of anything.
The other part about praying scripture, Julie and I learned from Beth Moore while we were in Arkansas. Very good stuff.
