I took the liberty of making a few changes in your quote. Hope you don't mind.
"Yes, millions of Jehovah's Witnesses have been shocked to learn that things they were taught as being vital for salvation are now considered by the Governing Body to be wrong. Have you, too, felt discouragement or even despair because of what is happening in the Organization? A publisher in Colombia expressed the effect the changes have had on many."Tell me," he asked, "how can I have confidence in anything? How can I believe in the Bible, in God, or have faith? Just ten years ago we Jehovah's Witnesses had the absolute truth, we put all our faith in this. Now the Governing Body and the Elders are telling us this is not the way to believe any more, but we are to believe 'new adjustments to our understanding.' How do I know the 'new adjustments' will be the truth in five years?"
