First Timothy 3:15 calls the church the pillar and foundation of the truth. It upholds the kingdom by being the school, the equipping place, and the place of support for world changers. But our focus must remain outside, not inside. We are to go from the “school” into the world and bring the powerful kingdom principles to bear on its problems…..When Christians change the goal of church and make it a place of conservation and escape rather than equpping and sending, we are working against the Great Commission. We are conserving crowds, not sending them out. We are hoarding kingdom resources, namely, people and their gifts. In many churches, God’s workers are in captivity. They are like prisoners and the pastors are the wardens.
