The Exercise of the Kingdom For the Building of the Church - God's New Testament economy is to build the church with Christ through the kingdom. The church is God's goal, God's desire and destination. His intention is to build the church. As we all know, in order to build anything we need certain material. The material for the building of the church is Christ. Along with the material, we also need the method of building. In Matthew 16 we see the goal, the material, and the method. The goal is the church, the material is Christ, and the method is the kingdom.
