church and kingdom

We know that "church" has lost its contact with our neighbours, right? I meet regularly with couples wanting to be married, and they have simply no connection to church as the catalyst of religion and spirituality. What are your ideas about how the kingdom of God is arriving, God's future in our present, in a society where the church is not the obvious answer? This is not just an interesting question, but a desperate one. If we were to dismantle "church" and re-assemble some other gathering sort of community what would that look like? Should we? I love the church and all it has meant to me over the decades, but I need to ask about how to re-imagine church for a new day, so that it truly is the vehicle for God's arriving Kingdom. Can we start over somehow?
