Great question.
It might help to read my first post to see where I'm coming from: http://www.jehovahs-witness.net/jw/experiences/196442/1/Fade-to-white
I became open with Witnesses who asked me why they didn't see me as often anymore, and told them straight out that I felt pure motives were very important, and if I didn't have those, I didn't belong with them at meetings- or anywhere else.
One former friend in particular said, "But you know that serving Jehovah is the only way to be truly happy! You can't give up now, the end is so close!"
To this I said, "Please, take a moment to really think about the words you are saying to me, and try to be objective. Though I have found much happiness despite leaving, if I do this so that I will be happy, that is an insincere motive. Jehovah would see right through that, wouldn't he. The same goes for coming back because the end is near. If I returned because these are the last days, that would be pure selfishness: to save my neck. (And there's STILL no fooling Jehovah on this.) The very fact that the end is near and yet I am NOT returning should only highlight to you how very serious I am about serving Jehovah only out of true love! You and I both know that Jehovah strictly disapproves of that kind of scrambling conduct to 'look busy'."
I had to do some doublespeak with her since at the time I no longer necessarily held to my former beliefs of the end being near, etc. (I really have no clue- how can anyone?) But I hope she considered my words, if not that day, at a quiet time later on. I have good reason to think she will apply some importance to what I said though I'm sure she'll never join all of us happy people on this site. She is a lifer unless something incredibly drastic happens. However, she admitted that she could not debate those points with me.
