text: if there can’t be light without darkness or good without evil? how can heaven be perfect? the garden of eden was apparently paradise and look what happened there, who says it won't happen again? i think there is duality in everthing.  the perfect balance of duality is the perfect balance of light and dark among other things.  that's why heaven can be considered perfect.  it's in perfect balance.....it's not lacking evil...it was always there, just in balance.
