A systemic disease is lurking inside the church that is derailing it from what God intended it to be, to know, and to do. That disease manifests in practical ignorance and isolation. If the church is to be healthy and thriving, its members must gain the needed know-how and skill sets to meaningfully engage with their increasingly difficult-to-reach unsaved neighbors, communities, and cultures in productive conversations about the good news of Jesus Christ. In other words, there must be a re-missioning of the body of Christ. ReMission practically equips leaders with tried-and-tested solutions that can outwardly mobilize a congregation, small group, or nonprofit ministry, and substantially increase the spiritual vitality of the body of Christ, both locally and globally. .
