I don't know if it is true but here it is.

  THE POWER OF A LETTER
 Most of you know John Wayne as an actor.  You may not
 know what happened to him before he died.  This is
 that story!  Robert Schuller's teenage daughter,
 Cindy, was in a motorcycle accident and had to have
 her leg amputated.  John Wayne is a big fan of Robert
 Schuller. He heard Dr. Schuller say on one of his
 programs that his daughter had been in an accident and
 had to have her leg amputated.   John Wayne wrote a
 note to her saying:  Dear Cindy, Sorry to hear about
 your accident.  Hope you will be all right. Signed,
 John Wayne  The note was delivered to her and she
 decided she wanted to write John Wayne a note in
 reply. She wrote:  Dear Mr. Wayne, I got your note.
 Thanks for writing to me. I like you very much.  I am
 going to be all right because Jesus is going to help
 me. Mr. Wayne, do you know Jesus?  I sure hope you
 know Jesus, Mr. Wayne, because I cannot imagine Heaven
 being complete without John Wayne being there. I hope,
 if you don't know Jesus, that you will give your heart
 to Jesus right now.  See you in Heaven.  And she
 signed her name.  She had just put that letter in an
 envelope, sealed it, and written across the front of
 it "John Wayne" when a visitor came into her room to
 see her.  He said to her: What are you doing?  She
 said: I just wrote a letter to John Wayne, but I don't
 know how to get it to him. He said: That's funny, I am
 going to have dinner with John Wayne tonight at the
 Newport Club down at Newport Beach.  Give it to me and
 I will give it to him.  She gave him the letter and he
 put it in his coat pocket. There were twelve of them
 that night sitting around the table for dinner. They
 were laughing and cutting up and the guy happened to
 reach in his pocket and felt that letter and
 remembered.  John Wayne was seated at the end of the
 table and the guy took the letter out and said: Hey,
 Duke, I was in Schuller's daughter's room today and
 she wrote you a letter and wanted me to give it to
 you. Here it is.  They passed it down to John Wayne
 and he opened it.  They kept on laughing and cutting
 up and someone happened to look down at John Wayne.
 He was crying.  One of them said: Hey, Duke, what is
 the matter? He said (and can't you hear him saying
 it), " I want to read you this letter." He read the
 letter.  Then he began to weep.  He folded it, put it
 in his pocket, and he pointed to the man who delivered
 it to him and said: "You go tell that little girl that
 right now, in this restaurant, right here, John Wayne
 gives his heart to Jesus Christ and I will see her in
 heaven."  Three weeks later John Wayne died. You never
 know how your witness to another will effect their eternity!
