Put simply, the church finds itself in a post-Christendom era, and it had better do some serious reflection or face increasing decline and eventual irrelevance.
A missional theology...appl ies to the whole of life of every believer. Every disciple is to be an agent of the kingdom of God, and every disciple is to carry the mission of God into every sphere of life. We are all missionaries sent into a non-Christian culture.
Because we believe that somewhere in the nest of paradigms contained in the phrase "missional church" lies nothing less that the future viability of Western Christianity.
Most churches don't have the resources for these tricks and inducements but are still bound to the imagination that church happens on a Sunday in a building.
