The world         to come, age to come,
                     or heaven on               ☉
  ☉       |        Earth are eschatological
               phrases reflecting  the belief
that the               current world or current age
           is flawed or cursed
           & will be replaced
in the future by a better world, age, or paradise.
The concept      ☉            is related to but differs
   from the concepts    ☉   of heaven, the afterlife,
and the Kingdom         of God in that heaven
         is another place or state generally seen
as above the world, the afterlife is generally
an individual's life after death & the Kingdom
of God could be in the present (such as Realized
eschatology)                ☉              [or the future]
