Fads - Teens of the church of Rick Warren play secular music in worship

The adolescent group of Saddleback Church pastor Rick Warren's, decided to play a song in praise of the group Mumford and Sons, a secular band known for talking about existential problems.
The video presentation has been posted on the Internet by the leader of the ministry, Pastor Joshua Griffin, and again raised the question about the lyrics of songs that can be played at the time of praise and worship in churches.
The Cave Music is about a person who feels an emptiness and found hope and a chorus of calls on the person who feels the same way through the cave and start living life as it should be.
