The New World Translation is worded to give the impression that the LIGHT ITSELF is what allows a righteous man to go where he needs to go. The implication is that TRUTH (from the Watchtower) is a gradual revelation from Jehovah. The ORGANIZATION becomes the __means by which___that light is shone. Compare that to the actual wording of the scripture:
Proverbs 4:18 (Young's Literal Translation)
18 And the path of the righteous [is] as a shining light, Going and brightening till the day is established,
Proverbs 4:18 (New King James Version)
18 But the path of the just is like the shining sun,
That shines ever brighter unto the perfect day.
To me, this is saying you can look at the road a good man is traveling (i.e. what his actions are; how he lives his life) and see where it leads him.
(Implying it leads to a perfect place to be.)
What does this discrepency of "meaning" interpretation tell us about the ROLE of the Organization as it sees itself?
