Paradise ends when Jesus returns to earth for the Final Judgement.
In Paradise souls are separated from their, dead, bodies, When Jesus returns to earth, all bodies will be regenerated, resurrected, as was the body of Jesus after he died. Souls in Paradise will be reunited with their regenerated bodies. Everyone enjoys new, renewed, arms and legs and hair and teeth and everything else.
Everyone in Paradise is already forgiven. All the charges against them have been dropped. Going through the Final Judgement will be like walking through the green channel at Customs. Jesus the Judge says ‘I know you! You were forgiven ages ago. I covered it all for you. Move on into your new life!’
The new life is a completely regenerated life. Our bodies’ DNA will be reinvigorated with life-energy. Our bodies will be recognisably the same, without the weaknesses and imperfections of this life. Our whole planet and whole universe will be regenerated, without the imperfections of this planet and this universe.
We will live, soul and body in a New Creation, New Heavens and a New Earth. (Revelation 21:1-7) Our regenerated eyes will see a wider range of colours. Our regenerated ears will hear a wider range of sounds. Life in all its fulness, more than we can ask or imagine.
