Do you think it's possible for Jehovah to change his mind so often on such an important subject?"---- I've asked this very question of my jw, his answer is that it is men who keep getting it wrong, somehow they must be interpreting things wrong and correct it at a later date. Ain't it wonnerful how the gb can admit their mistakes?
That leads us to ask if we should follow men or God? But the fds is...... you know the routine.
Then you can try to point out that the gb/wt never admits mistakes when giving new light, it simply appears in a new wt with not a word said about being mistaken or wrong or false prophets. Every jw simply goes along as if this is quite normal and then forget they ever believed anything different about a subject or that it even matters that this information is supposed to from God. No? Not directly from God you say? Only guided? define both. If the wt is only the interpretations of men who can have a history of being mistaken, then if you leave the org is it equated with leaving jah Himself? round and round you go.
