God intends that Christ have the preeminence in all things (Col. 1:18) and that Christ be all in all the believers (Col. 3:10-11). Our experience of Christ brings us into the reality of God’s house, which is the church today (1 Tim. 3:15) and New Jerusalem in eternity. The enlargement of God’s house is God’s city. Through the house and city God in Christ will reign over and bless the whole earth.
