The first time I saw this band I was working in maintenance at Calvary Chapel Fort Lauderdale. We had this concert series happening at the time where hip, Christian acts were brought in to give greater exposure Christian artists and the message of the Gospel. Jars of Clay was the opening act/road crew for PFR (also known as Pray for Rain). Little did anyone know that PFR was on the way out while Jars was just making their ascent to worldwide fame.
Jars of Clay started an organization called Blood:Water Mission that drills wells in Africa. I blogged about the young lady they hired as executive director over on Missionary Scribbler. She's quite an inspiration.
