A few weeks ago I was in a workshop listening to workers from around the world report in on progress in fueling church planting movements.
One of them served in a hostile environment. He had seen a number of movements among different people groups. Exciting stuff, until new believers started disappearing.
In one case a whole family was never seen or heard from again. They were either murdered, or lost somewhere in the prison system. Nobody knows.
About twenty minutes later in the workshop a visitor raised a concern regarding rapidly expanding movements. He told us he had heard they are not “deep”.
I didn’t get a chance to ask him what “deep” meant. I was just stunned that such a question could be asked of people who were laying down their lives for the sake of the gospel.
Deep can mean different things to different people—mature, knowledgable, wise. In church planting movements, "going deeper" means learning to obey what Jesus commanded.
