Light Gets Brighter
Jehovah's Witnesses claim to be the only group to teach truth, as revealed to their Governing Body by Jehovah. If this is the case, why has Watchtower doctrine experienced ongoing changes? Watchtower justifies this as the "light gets brighter." This article examines the logic behind such a claim.
A key premise of this site is that constant changes in doctrine and failed predictions are clear indication that Jehovah does not direct Watchtower. For the external observer this is the logical conclusion, yet for one of Jehovah's Witnesses it barely raises a grimace. How can this be? Because changes and failures are immediately dismissed by the thought stopping concept:
Does truth change?
"The Bible tells us the light would get brighter."
This is based on a phrase from Proverbs.
"But the path of the righteous ones is like the bright light that is getting lighter and lighter until the day is firmly established." Proverbs 4:18
Addressing this claim is required to render the information contained within this site effective.
The main justification from the Watchtower for changed doctrine is Proverbs 4:18.

““The path of the righteous ones is like the bright light that is getting lighter and lighter until the day is firmly established,” states Proverbs 4:18.

Another way to cooperate with Christ’s “brothers” is to have a positive attitude toward any refinements in our understanding of Scriptural truths as published by “the faithful and discreet slave.”” Watchtower 2011 May 15 p.27 (Contines...worth a read)
