Hi amicus, did some searching and here is one that is close: It is from the 8/15/97 WT
13 In the meantime, we do well to heed the direction given by the 'faithful slave.' (Matthew 24:45) For over a hundred years, the modern-day "slave" has faithfully served as a "watchman." (Ezekiel 3:17-21) The Watchtower of January 1, 1984, explained: "This watchman observes how events are developing on earth in fulfillment of Bible prophecy, sounds the warning of an impending 'great tribulation such as has not occurred since the world's beginning' and publishes 'good news of something better.'"-Matthew 24:21; Isaiah 52:7.
14 Remember: It is a watchman's job to call out "just what he sees." (Isaiah 21:6-8) In Bible times a watchman would sound a warning even when the potential threat was too far in the distance to be clearly identified. (2 Kings 9:17, 18) False alarms surely occurred back then. But a good watchman would not hold back out of fear of embarrassment. If your house was on fire, how would you feel if the firemen failed to appear because they figured it might be a false alarm? No, we expect such men to respond quickly to any sign of danger! In a similar manner, the watchman class has spoken out as circumstances seemed to warrant doing so.
15 As events develop, though, our understanding of prophecy has become clearer. History shows that rarely, if ever, are divine prophecies fully understood before their fulfillment. God told Abram exactly how long his seed would be "an alien resident in a land not theirs," namely, 400 years. (Genesis 15:13) Moses, however, offered himself as deliverer prematurely.-Acts 7:23-30.
16 Consider also the Messianic prophecies. In retrospect it seems crystal clear that the Messiah's death and resurrection were foretold. (Isaiah 53:8-10) Yet, Jesus' own disciples failed to grasp this fact. (Matthew 16:21-23) They did not see that Daniel 7:13, 14 would be fulfilled during Christ's future pa·rou·si'a, or "presence." (Matthew 24:3) So they were almost 2,000 years off in their reckoning when they asked Jesus: "Lord, are you restoring the kingdom to Israel at this time?" (Acts 1:6) Even after the Christian congregation became well established, erroneous ideas and false expectations continued to crop up. (2 Thessalonians 2:1, 2) Though some occasionally had mistaken views, Jehovah undeniably blessed the work of those first-century believers!
17 Today's watchman class has likewise had to clarify its views from time to time. Can anyone doubt, though, that Jehovah has blessed the 'faithful slave'? Besides, viewed in context, are not most of the adjustments that have occurred relatively small? Our basic understanding of the Bible has not changed. Our conviction that we are living in the last days is stronger than ever!
