"Not Religion, But Relationship" WHY RADICAL? As a Christian, it’s good to be radical. It means you’re going to the root of the matter instead of dealing with and living on the surface. To be radical means to return to the way God would have things. It means you view church life as coming out of the root, the way God intended the church to be. As church, our mission then, is to go back to root of the first Christian church, as found in the book of Acts.
