Ok, so my awesome friend Alex did some research and found the infamous quote that has caused so much trouble (at least for me!) and who to attribute it to. The one I had posted was kind of a paraphrased version of this one...but pretty much the same message. So, here ya go, with proper documentation and everything!
"You, the youth of the church today, were generals in the war of Heaven.
Someday when you are back in the Spirit World, you will be enthralled by other souls who will be from many other interesting time periods and who lived during the time of many great prophets.
You may ask one person, "When did you live?" and hear something like, "I was with Moses when he parted the Red Sea," or "I helped build one of the great pyramids," or "I fought with Captain Moroni."
And as you are standing there amazed at the people you are with, someone will ask you during which prophets' time you lived in; when you tell them that you lived during the time of President Kimball, President Benson, President Hunter, and President Hinckley, a hush will fall over every hall and corridor of Heaven and all in attendance will bow in your presence.
This is a very important stewardship we have been given. We were held back for 6000 years because we were the most righteous, most talented, most obedient servants of our Heavenly Father."
ARE WE STILL? -- quoted by Brad Wilcox, at Especially For Youth
An Early-Morning Seminary Teacher in Texas wrote (April 1999):
This quote is by Jack Marshall and is used by Brad Wilcox in his book "Tackling Teenage Troubles" on page 26 and 27. I called to confirm this just last week for our CES coordinator by calling the Church Office Building. It is being attributed to many of the Brethren but Jack Marshall is the one who made this statement. I was told by the secretary whom I spoke with that Jack Marshall is a popular youth speaker. I have a bio on him in the book "High Fives & High Hopes: Favorite Talks Especially for Youth". It states: Jack S. Marshall is an institute director in Pasadena, California. He is a popular speaker at youth programs and has published articles in the New Era, coauthored a book, and released two audio tapes of favorite talks. He and his wife, Liz, have five children.
