Church in trouble, "Doing Christians" needed. The denominational protestant church in America is in decline. The non-denominational protestant church in America is growing. The biggest difference between them is the core belief, coupled with action, by the non-denominational church that serving others is a driving force in the life of a Christian. Instead of cultivating "believing Christians" who stop short of acting out the prime directive of Jesus - to serve others - churches need to spend as much time enabling and expecting action for the "least of these" as they do for the traditional elements - salvation, bible knowledge and cultural moral positions. "A Call to Service" provides a resource to engage, enable and empower individuals to become "doing Christians" helping usher in the kingdom of God here on earth.
