afflict the comforted

This morning I turned on the radio in my car and there happened to be a pastor preaching. I listened for a while and figured out that he was from a small, rural, pentecostal church. Right before I got out of my car he ended a prayer with the following sentence that I haven't been able to get out of my mind all day:
"And Lord, would you comfort the afflicted and afflict the comfortable?" Maybe that is a prayer that is prayed often, but I have never heard it before. It has stuck with me. Sometimes the comfortable need some affliction. We all seek and strive for comfort, but the absence of comfort cause us to grow, change, and stretch ourselves. Great thought. Way to go rural preacher dude- whoever you are.
