The unanwserable Christian question about the tree of healing after satan is cast in hell forever

22 Then the angel showed me the river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb 2 down the middle of the great street of the city. On each side of the river stood the tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations. 3 No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. 4 They will see his face, and his name will be on their foreheads. 5 There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.
Now here if you look this up you will find that the old earth is destroyed and the new heavens and the new earth are now with all the people that made it to heaven.
now here is the question.
WHAT THE HELL IS THERE LEFT TO HEAL? ALL THINGS ARE NEW AND THIS DAMN TREE IS NOT GOING TO ONCE,NOT TWICE BUT EVERY DAMN MONTH BEAR IT LEAVES FOR THE HEALING OF THE NATIONS.

How many months are there in eternity ffs?
Come on,satans is in hell,the antichrist is in hell death is in the fire also and we still need healing of nations.
I really do worry about the bible some times.
