In Revelation 3:12 the Lord Jesus promises, “He who overcomes, him I will make a pillar in the temple of My God, and he shall by no means go out anymore, and I will write upon him the name of My God and the name of the city of My God, the New Jerusalem, which descends out of heaven from My God, and My new name.”
The pillars in God’s temple are living persons, people closely identified with God, New Jerusalem, and the Lord Jesus.
This, like many other verses (e.g. 1 Cor. 3:9, Eph. 2:21-22, 4:15-16, 1 Peter 2:5) show that God’s New Testament building is spiritual. God’s building of Himself into His people and His building His people together has replaced the physical buildings of the Old Testament.
We will not merely be in New Jerusalem (with the possibility of going out) but built into it so that we “shall by no means go out anymore.” This city is a living building joined/fitted/knit together in life, as are the members of our physical body.
Revelation 21:22 tells us that the Triune God is the temple of New Jerusalem—“the Lord God the Almighty and the Lamb are its temple.” And the overcomers are being built into this living building as pillars during this age and fully in the coming kingdom age. Nothing physical about this. In eternity all God’s people will be built into New Jerusalem and into the temple.
Lord Jesus, grant us grace every day that we may cooperate with You to overcome. Build us into Your building and write Yourself and New Jerusalem on us.
