Energion author D. Kevin Brown doesn’t think that’s such a good idea:
Through the years, I’ve become more and more dismayed that we no longer mix our young people with our adults in our churches in any way. We keep our youth in their own rooms, as far away from everyone else in the church as possible, in case they get too loud or rowdy. We let them paint the walls tie-dyed, put up posters of Christian musicians, many of whom honestly look like leftovers from the 70’s group KISS, and bring in sofas for them to lounge on while they play video games and hang out. Some youth rooms I’ve seen look more like arcades. Some churches have even given their youth their own building, where they come for an entertainment smorgasbord anytime they want. Is this the structural model we really believe is going to grow mature, solid, faith-filled, Christ-centered, young adults? We must stop kidding ourselves. The numbers, the surveys, and the statistical data do not lie. Many of our young adults continue to abandon their faith and will continue to do so unless we change our strategy and return to a Biblical model.
