Wow! My heart has been provoked to a holy 'jealousy' as I listen to the intimacy, authority and command of scripture found in the messages in the following podcasts. Most of the content comes from IHOP - The International House of Prayer (Kansas City).

First get iTunes free here: http://www.apple.com/itunes/download/

I recommend that you start with ' The Power of a Focused Life" from the podcast "Yearn, Faint, Cry…Worship Podcast."
You will also find a 20-part study on the Song of Songs, plus TONS of other stuff.

Also check out "The Prayer Podcast". Don't need itunes for this one, but it helps!

Now, no conference, sermon or podcast can make you a 'better' christian, or change your life for good - it can only make you hunger for the Lord. It's one thing to listen about the importance of prayer and fasting - its another to do it. So may these podcasts wet your appetites (like the smell of fresh baked bread), may your spirit's hunger for His word be intensified as you listen.
