Does modern worship fail by trashing the line between the sacred and secular?

A few years ago, a young adult very openly expressed his frustration with worship at church. “Rich, why is it that I feel closer to God at a Coldplay concert than I do at church?” This was a stunning admission, because it represented not just his experience but that of many and perhaps spoke to some doubts in my own mind. However, what came from this conversation changed how I viewed worship in church. Worship at church should either be made more like the secular music out there, if that is truly more spiritual. Or, there is something missing in the worship at church that needed to be changed. I tried the first, making relevancy a goal, but I think that hand has been overplayed. So, I am left with the second idea. What is missing?
