For a number of reasons; the reasonably anti-establishment attitude of our postmodern world, the busyness and burnout of our fast past culture, the nature of the mega church (1000 plus people), a fresh appreciation by church leaders in regards to what a Sunday service can and cannot achieve in the life of a believer, and so on, the 21st Century Church, (at least the Australasian Charismatic/Pentecostal churches I am most familiar with), has pulled back a lot on the expectation it has for its church members. Where members were once encouraged and expected to attend two services on a Sunday, attending one is now OK. Where members were often serving in multiple departments or areas of the church, one area of service is a more healthy expectation. All sorts of things have changed. I'm all for most of them. Without losing the fact that the church is central and essential to God's plan for redemption in the world; a de-institutionalisation of some aspects of our spiritual walk is a healthy thing.
What is unhealthy is a distortion of what it means to follow Christ. We cannot afford to reduce Christianity to a prayer asking for forgiveness and then leave it at that. To do this is to promote and underwhelming Christianity. A version, if it can be called that, of Christianity which is most likely not Christianity at all.
To follow Christ, to be a disciple of Christ, means a whole new way of life. It means a whole new worldview and approach to everything we do. New goals, new priorities, new purpose, new standards, new ways of measuring success, new paradigms, new attitudes, new hope; a whole new life.
An underwhelming Christianity will not draw a new generation to the things of God, it will push them away. The Millennial Generation (Gen Y) live in a world where upgrades, expansions, modifications, extra additions, add ons, and so fourth are available in every area of life from their iPods, to their facebook page, to their cars, to their own bodies. Following Christ is not an addition to ones life it is a whole new way of life. And that is the very thing about Christianity that will attract the next generation. This is the thing that I love about my faith, about following Christ, yet after living my whole life as a Christian, I think I am only just beginning to get it.
The next generation has to get it from the start.
I haven't read the book yet, but I think these guys are getting it.
