I recently noticed that Rev. 21 clearly says there will be no temple in the New Jerusalem, yet Rev. describes a temple existing there. Am I reading/understanding wrong, or does this indicate a different perspective in the channeled letters from Jesus in Rev. 1-2 compared to John's visions in the rest of the book?
The one who is victorious I will make a pillar in the temple of my God. Never again will they leave it. I will write on them the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on them my new name. (Rev. 3:12)
I did not see a temple in the city, because the Lord God Almighty and the Lamb are its temple. The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp. (Rev. 21:22-23)
In the first passage, the temple of the New Jerusalem exists; and the victorious Christian will never leave it. In the second, the is no temple in the New Jerusalem because God and the Lamb are its temple. God's temple is also referred to several other places in Revelation, such as Revelation 11:19, 14:15, Revelation 15:5.
Is there a Temple in the New Jerusalem? If not, how should we understand the existence of the Temple in chapter 3, where the New Jerusalem is specifically mentioned, as well as in various other parts of the book?
