God is the Alpha and Omega. He created everything from the vast Universe to small quarks. He created the human beings with 23 pairs of chromosomes with 4x10^171 possible variations (that's a 4 with 171 zeroes behind it) He created complex emotions and abstract thoughts. Something mankind still can not duplicate with the most complex computing devices. He has harnessed the power of fusion. He has been able to preserve and keep accurate a 6000 year old text meandering through generations of language and cultural changes. He is truly an awesome being.
Yet some how, he can't clearly communicate through an individual or group of individuals in New York. He has a life saving message for mankind yet he is unable to clearly publish it through his own earthly organization he commissioned. A human could easily accomplish this task.
If the CEO of Ford Motor Company gave an important, simple address to his board to pass to all of his employees and they failed in this attempt they would be fired immediately. No matter how ernest they were in their duties.
The WBTS wrote in their literature angels direct the writing of the publications. Ask honestly why have the publications been wrong. Is a powerful, instrument of an awesome God incapable of passing along a simple message. The question has to be asked. Who lied the angel directing the writings or the person doing the writing? This is a circular argument which needs no answer. If the messenger lied, it proves they are imbedded with the spirit of deceit and Satan, or the writer lied and is propagating lies marking him as the source of evil and ally of the Devil. Answers A and B both arrive at the same conclusion.
Sometimes, people of power only release small portions of information at a time to control their organization. I have had to do this in my own business life. I only tell what is needed to be known to control money, personal, and attitudes until the appropriate time. This is how the light gets brighter. It is a tool used by people everyday. The perfect example is educating ones children about sex. An individual wouldn't start with every detail to his or her two year old child, but as their knowledge and mental processes develop we add information. We don't tell them false information, after false information and then try to give them the correct information in the end. So the "light gets brighter doesn't work here".
Remember the light gets brighter. It doesn't change colors.
