Revekation 22:3

Verse 3 “And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him:”

Now we are told there is no more curse. Everything is brought back to the original state of perfection. This is where the world started. Back in Genesis I had said that the world will exist in five states. Perfection, antediluvian state, present state, millennial state (which is the same as the antediluvian state) and then perfection - a perfect cycle. As it now says there is no more curse, it would seem that the leaves of the tree that are said to be for healing would not include healing disease, as disease is a result of the curse. As it appears that the people coming through the millennium might not get glorified bodies, which would make sense as they do not die, it would seem that the leaves are just for anti-aging and in case someone gets hurt, as the bodies we have now can get injured, even in a perfect world. It would also appear that as there is no more curse, there may not be any more children being born, as (can be seen from the millennium) even when the Lord reigns, the path of destruction is broad, and the path of life is narrow and few be there that find it. Were children to be born, many would have to be executed due to their choice to rebel against God. If that were so, the curse would not be lifted, which it says that it is.

God and the Lamb will be in New Jerusalem and all of those who have believed in Him will serve Him forever.
