A key is missing in Christianity today. It is a critical key. Without the full use of this key, followers of Christ lack the tools needed to fully live as kingdom representative on earth,what is the missing key? discipleship. Kingdom disciples are in such short supply.Until this key called discipleship is recovered and utilized, we will continue to fail in our calling to adequately live as kingdom representative on earth. Discipleship is the missing key to a life of authority under God. But surrender to Christ's lordship and obedience to His rule of love are grooves that make up that key, which when used rightly will unlock the power to bring heaven to bear earth.
