War In Heaven And The Christmas Gift Poem by Spock the Vegan

"And there was war in heaven: Michael and his angels
fought against the dragon; and the dragon fought and
his angels,  and prevailed not; neither was their place
found any more in heaven. And the great dragon was
cast out, that old serpent, called the Devil, and Satan,
which deceiveth the whole world: he was cast out into
the earth, and his angels were cast out with him."
(Isaiah 12: 7-10)

Mankind was sent to dwell in Earth with Satan there
To temp them.

"And Cain talked with Abel his brother: and it came to pass,
when they were in the field, that Cain rose up against Abel
his brother, and slew him." (Genesis 4: 8)

Sins have a consequence of death, so a Savior was needed.

"For the wages of sin is death; but the gift of God is 
eternal life through Jesus Christ our Lord." (Romans 6: 23)

There is only one Savior for the whole world.

"be it known unto you all, and to all the people of Israel,
that by the name of Jesus Christ of Nazareth, whom ye
crucified, whom God raised from the dead,  even by him
doth this man stand here before you whole."
"Neither is there salvation in any other: for there is none
other name under heaven given among men, whereby we
must be saved." (Acts 4: 10,12)

He will save anyone who accepts him as their Savior.

"For God so loved the world, that he gave his only begotten
Son, that whosoever believeth in him should not perish,
but have everlasting life." (John 3: 16)
