Anyone seeking to find his way on a pitch black night
through an unfamiliar environment
without the aid of a candle or a light would find it to be virtually
an impossible task.
Very quickly he would
become completely and hopelessly lost.
While groping around in the darkness, his hand perchances touches
a tree, but because he is unfamiliar with the
area he is in, the tree would provide him
with absolutely no useful point of reference.
He would still be lost.
Brethren, any attempt to find your way through the unfamiliar realm
of the spirit without a light to guide you
would have the undesirable result of you being absolutely confused and
This state of bewilderment and confusion is what the scripture means by the
expression "lost soul".
A lantern that emits a bright light would be heaven sent to a person
who was lost in the woods under total darkness.
Jesus Christ is the Light of the world and was Heaven
sent by God the Father to seek and to save the lost.
