We used this video in our "Light On The Hill" service last night...thought it was pretty cool. It really makes you look at yourself your church and examine the differing opinions, criticisms and griping that are always seem to arise when discussing "worship" in a corps or church.
The devil will use anything he can to drive a wedge between God's people and their relationship with Him. Just remember that the church can be one of Satan's greatest weapons against God...
