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.
When the church is in mission, it is the true church. The church itself is not only a product of that mission but is obligated and destined to extend it by whatever means possible. The mission of God flows directly through every believer and every community of faith that adheres to Jesus. To obstruct this is to block God's purposes in and through his people.
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.
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.
If we can embrace the adventure and risk and equip our churches to lay down their lives and abandon their inherent loss-aversion, who knows what innovation, what freshness, what new insights from the Spirit will emerge.
Heroes are important not only because they symbolize what we believe to be important, but because they also convey universal truths about personal self-discovery and self-transcendence, one's role in society, and the relation between the two.
