This is for Loni who requested a copy of a Left Behind
Letter.  Raptureready has a whole slew of them at this
link and you can take your pick.

Here's just one example of one, and I think it is
pretty good:
 

Dear Tribulation Saints,

I'm writing to you to explain what the government and
talking heads will try to explain away. The millions
of people that have disappeared were not taken by some
UFO in the sky and they weren't vaporized into
nonexistence by whatever sub-molecular theory
physicists have gravitated towards.

What you've witnessed, what even time cannot reduce in
significance or splendor, was the rapture into heaven
of every born-again person who had an intimate
relationship with the Lord Jesus Christ. Good news for
us, but better for you. Can any other unbeliever
throughout the centuries after Jesus claim to have
received such an obvious second chance than
yourselves? Of course with every good comes a bad.

You must not only live through the most tumultuous
time in human history, but you must face a man who
will eventually become possessed by Satan himself.
This man, the Antichrist, will have two reasons for
living--to kill those who trust in God, and to have
the rest bow down in worship before him. For your
eternal future and everything else you hold sacred,
please do not become a part of this second group.

He will distinguish between groups by making those who
worship him take his mark. No matter what, no matter
the torture or lives being held over you--DO NOT
ACCEPT THIS MARK! To do so damns you to a hell that
doesn't contain red-suited devils with horns and
tails, to do so damns you to an eternal torment and
separation from God and everything else that is good.
It always better to lose your life than your soul.

But I'm getting ahead of myself. The Antichrist will
make his arrival by signing a seven-year peace treaty
with Israel. From the time of this signing, you can
determine the physical coming of Jesus Christ at 2520
days (seven biblical years). Halfway through this
covenant the Antichrist will declare himself God,
instigating a series of judgments similar to those
used by Mosed to free the people of Israel from Egypt.
 

All of this is in the Book of Revelation--read it! I
recommend you buy a Bible before they become outlawed.
I also recommend you buy a water purifier, lots of
canned goods and everything else you'll need in the
coming years to sustain yourself and fellow believers.
 

Don't worry, God does not hate you. These events are
preordained and being done to rock that false sense of
security you may have been living with. Repent of your
sins. They will be forgiven, large or small, and
accept the Lord Jesus Christ into your heart. He loves
you more than you could ever imagine.

And watch the sky, we're coming back, trailing Jesus
in numbers you saints will more than surpass. You now
know when.

God Bless and trust in Him as you have no other.
