At the end of life, there happens what C.S.
Lewis called, "the great divorce"; it is the
divorce between that which is good, and
that which is evil, between those who know
Jesus as their Savior, and those who have
not.

They need to know the difference between
Heaven and Hell; between the blessings
and the joys forever of Heaven and the
awful sense of loss and regret as well as
the suffering that will be for those who will
live eternally in the Lake of Fire.
