It’s possible you’re looking at things from the wrong viewpoint shown John.
Rev 4:1 After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and
I will shew thee things which must be hereafter. (From when?)
Rev 4:2 . . a throne was set in heaven, and One (Jesus on His own throne) sat on the throne.
Rev 21:1 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.
Things to look for?
Rev 21:2 And I John saw the holy city,
new Jerusalem, coming down from God out of heaven . .
Rev 21:4 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.
