The answer might be indicated by how you view theocratic direction now. If you trust the direction we receive today and readily obey, you will likely do the same during the great tribulation.
Anyone can pull a scripture out of their hat to "prove" their argument. My reply to the above statement would be to use the WT own words, "The governing body is neither inspired or infallible." And that they are "imperfect men." Then refer to (Luke 6:39) . . .Then he also told them an illustration: “A blind man cannot guide a blind man, can he? Both will fall into a pit, will they not?
If the governing body is NOT inspired they are in effect "blind". I do not see any benefit to following a blind guide.
