Awakened at G. - Thank you very much for posting the "ever-brightening-light" verse, along with its accompanying context.
It is plain to see that the Witnesses have been woefully duped.
First of all, the book of Proverbs, like the book of Ecclesiastes, was written within the genre of Wisdom literature. Unlike prophetic literature [i.e. the books of Isaiah; Ezekiel; Jeremiah; etc.], Wisdom literature does not even claim to get its insights into life from some sort of divine revelation, but rather from a deep, contemplative understanding of the world and how the world works. The book of Proverbs is based on knowledge acquired over the span of many generations of thinkers and sages. The book of Proverbs does not even pretend to concern itself with prophecy or eschatology. It does not even claim to have anything to do with foretelling future events. The book of Proverbs deals with the question of how to live morally; its emphasis is on ethics, and not at all on teleology.
Using poetic and metaphorical language, the passage in question sets up an antithesis, a dichotomy:
righteous people on bright, and ever brightening, path/ wicked people on gloomy, and ever darkening, path
Using poetic speech, this passage counterposes two diametrically opposed moral conditions [or states of being] in general. I really do not see this passage as concerning itself with scriptural knowledge or exegesis. Its focus is very broad and generalized.
It's ironic to think that it is with the wicked ones in this passage that the Watchtower can be associated. When one considers how the Witnesses have stumbled around in the gloom of their own delusions and failed prophecies, one realizes that they can be classified as belonging in the right-hand side of the dichotomy that I described above.
As for the Witness doctrine on the annointed and "this generation," it is tripe, wrapped in bilge, wrapped in nonsense, wrapped in bullshit. In regard to the "doctrine" of the annointed, how can they even calculate the number of remaining annointed when there exists no way of determining who is annointed!!! How can you calculate a quantity that is so nebulous?! According to Witness doctrine, people "profess" to be annointed. Anyone can "profess" to be anything that they imagine themselves to be. However, as I see it, there is no way to quantify the number of people who all-so-subjectively profess to be members of a certain group. Perhaps the term subjective is the crucial one here. In order to quantify something, there must be at least one objective criterion, although two or more objective criteria would be better. But if there exists not one single objective criterion, then quantification becomes an exercise in utter futility.
