How will breathing work in the New Jerusalem?

Gonna guess god will use his magic

God tells us that He will give us new resurrected bodies. I assume that those words mean that we will not need many of the things we need at this present time. I'm looking forward to finding out all these things - how about your?

What makes you think that in Heaven you will need the same breathing ability that is required on earth? If God can bring you back to life after your death then I'm sure that He'll have taken care about providing the correct atmosphere for your survival IF you are one of those takes to be with Him for eternity.

Revelation 1:1 states: A revelation by Jesus Christ, which God gave him, to show his slaves the things that must shortly take place. And he sent his angel and presented it in SIGNS through him to his slave John.

Imperfect humans cannot comprehend spiritual creatures or the things that go on in heaven. That is why God used physical things to describe heavenly things.

Notice what else the apostle John says: “I saw also the holy city, New Jerusalem, coming down out of heaven from God and prepared as a bride adorned for her husband.”​—Re 21:2.

So New Jerusalem, here is described as a bride, not a box.

Another description is: and he showed me the holy city Jerusalem coming down out of heaven from God and having the glory of God. Its radiance was like a most precious stone, as a jasper stone shining crystal-clear.”​—Re 21:9-11.

New Jerusalem is the Kingdom of God that will rule over the earth, made up of the chosen ones of Jehovah. (Revelation 5:9, 10)

No literal city could ever have such measurements. Revelation was given in signs, symbolic.(1Kings 6:19,20; Ps.83:18)

The 144-cubit-high walls remind us that the city is made up of ONLY 144,000 spiritually adopted sons of God. The figure 12 that appears in the 12,000-furlong measurement of the city​—with the length, breadth, and height being equal—​is used figuratively in organizational settings in Bible prophecy. New Jerusalem is a superbly designed organizational arrangement for accomplishing God’s eternal purpose, with the King Jesus Christ. Then there is the shape of the city: a perfect cube. This New Jerusalem, illuminated by the glory of Jehovah himself, is seen as a perfect, large-scale cube, all its measurements are perfectly balanced. It is a city without irregularities or defects.​—Rev.21:22

God's Kingdom/New Jerusalem will rule FROM the heavens TO the people LIVING ON EARTH. Read Ps.37.

Who is God going to rule over the earth if half are in heaven & the other half in hell?

No air

Windows and doors......What makes you think than our glorified bodies would need to breath?

The New Jerusalem is people, not a city.

spirits don't need air.......

Start from the beginning again

Revelation 21:1-5 Authorized (King James) Version (AKJV)

21 And I saw a NEW heaven and a NEW earth: for the FIRST HEAVEN and the FIRST EARTH were PASSED AWAY; and there was no more sea. 2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. 3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. 4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the FORMER things are PASSED AWAY.

5 And he that sat upon the throne said, Behold, I make ALL THINGS NEW.
