"The problem is the way we do church: 'the world coming to the church' rather than 'the church going to the world'. Thus, the need to have a centre to do ministry becomes urgent, and thus the focus on buildings."
That hits the nail on the head doesn't it. I mean, what did Jesus command before he ascended? To go out into the world right? Are we fulfilling this command when we build mega churches to house congregants? Are there any churches out there that recruit, train, and send out congregants into the world to spread the Gospel? Wouldn't such a method be closer to what Jesus commanded?
