Good evening folks! We have encountered this advice countlessly on WT study articles. This especially comes out to ease the waiting pain of brothers eagerly waiting for God's new world and the end of the old system of things - with all the sufferings that go along with it.
I also noticed this being floated to try to extend the patience of brothers who are jumping ahead of the organization in terms of thinking - as if they are pre-empting the organization on certain sensitive views and issues.
If a brother has gotten an idea or insight that is far more superior than the present affairs in the Society, or regarded as way in advance - he can be branded as a brother "not in order". It is as if the brother has committed a flaw to draw attention on him. It is as if he should have just be content in waiting for changes before being too preemptive.
My personal experience is truly revealing. We have 4 elders only sometime 1 1/2 years ago. In my desire to help the BOE, I have initiated to meet with my fellow Ministerial Servants to draw out plans and suggestions to make the elders work less stressful. The main idea was simple - help the BOE. We came out with minutes containing constructive suggestions. Suddenly, then the Presiding Overseer and another elder saw the work as encroaching the rights and privileges of an elder. They thought there was no such thing as body of Minsiterial Servants. In other words, what we thought were very practical action plans, had in fact no use at all. Even the MS who's a bethelite was stunned to hear the views of this PO. I felt so frustrated since the brothers (MS) combined their wits to come up with sound recommendations and a system. Instead of commendation, we got bashed, our motives even got questioned. End of the story.
This has led yours truly to believe that the exhortation to "Wait on Jehovah" is sometimes a misnomer. WT should have just re-phrase it into: "Wait on the WT leadership to make the necessary changes. Don't initiate things too much. Or you may find yourself in trouble."
