Our service in the church must be in fellowship with God. In order to serve God and His people, we need to fellowship with Him. This is the first basic and fundamental matter related to our service. However, we also need to realize that we should serve in fellowship with one another. We are in Christ and in the new creation as members of His Body. Thus, we cannot do anything by ourselves in an independent way, because each of us has a different function in the Body of Christ. The building up of the Body of Christ is the primary matter. All the service and work of the church are for the purpose of the building up of the Body of Christ.
