Of course, IHOP-KC is a great resource especially with their services live online. They began 24/7 prayer in 1999 and are still going. Watch the live prayer room here.
Mike Bickle, the director of the International House of Prayer has his teachings available with free .pdf notes, mp3 downloads, video streaming at www.mikebickle.org . It's really cool to download an mp3, print out the notes and listen on your iTouch at your leisure. The IHOP prophetic history is amazing. I cannot underestimate how life changing it is to hear of the supernatural occurrences that have occurred as God proclaims that 24/7 worship is on his heart.
The Wilderness Outcry event in Missourri is a much needed event for the body of Christ. We need to unplug and get away into the wilderness to seek his voice. We will not have all the busy noise and also will remember that God takes care of us, not our government, cell phones, jobs, sewer systems, electrical grids, etc. He takes care of us like he took care of the Israelites in the desert.
