Letter from Hell

I received the following in an email, the author is not known. The lesson from this will be self evident.

THE LETTER FROM HELL

One day a woman named Louise fell asleep in her bed, and dreamed
a very fitful dream. She dreamed that someone in Hell wrote a letter
to her, and it was to be delivered to her by a messenger.
The messenger passed between the lakes of burning fire and
brimstone that occupies Hell, and found his way to the door
that would lead him to the outside world. Louise dreamed that the
messenger walked to her house, came inside, and gently but firmly
woke Louise up. He gave her the message, saying only that a friend
had wrote it to her from Hell. Louise, in her dream, with trembling
hands took the letter and read:

My Friend, I stand in Judgment now, 
And feel that you're to blame somehow. 
On earth, I walked with you day by day, 
And never did you point the way. 
You knew the Lord in truth and glory, 
But never did you tell the story. 
My knowledge then was very dim; 
You could have led me safe to Him. 
Though we lived together on the earth, 
You never told me of the second birth, 
And now I stand this day condemned, 
Because you failed to mention Him. 
You taught me many things, that's true, 
I called you "friend" and trusted you, 
But I learn now that it's too late, 
You could have kept me from this fate. 
We walked by day and talked by night, 
And yet you showed me not the Light. 
You let me live, and love, and die, 
You knew I'd never live on high. 
Yes, I called you a "friend" in life, 
And trusted you through joy and strife. 
And yet on coming to the end, 
I cannot, now, call you "My Friend." 

Marsha

After reading the letter, Louise awoke. The dream was still so real in 
her mind and sweat dropped from her body in pools. She swore she
could still smell the acrid smell of brimstone and smoke from her
room. As she contemplated the meaning of her dream, she realized
that as a Christian, she has failed in her duty to "go out to all the world
and preach the gospel." As she thought of that, she promised herself
that the next day, she would call Marsha and invite her to church with
her. The next morning she called Marsha and this was the conversation:

"Yes, Bill, Is Marsha there?" 
"Louise, you don't know?" 
"No, Bill, know what?" 
"Marsha WAS KILLED LAST NIGHT IN A CAR ACCIDENT. I thought you had known."

Fellow Christian, is this your testimony? Are you witnessing to your 
friends that you are with everyday? Or will there be a friend of yours 
in hell, asking you why you did not tell them about JESUS?
