Personally I'm more interested in signs from Satan and the demons than signs from God. I always heard that as soon as you started becoming weak in the JW faith the devil would pounce on you like a roaring lion.
I was told the primary way he did this was by throwing temptation at me, the most common being loose women. Here I am a few years into my fade, with almost dead faith, and I'm not so lucky. Stan (that's my nickname for Satan now) hasn't thrown me one bone (giggity). Much less the 25 top model quality women that I openly agreed to selling my soul for if they would suddenly appear with immediate lust for me within a short time frame. And you know what ... I got nuthin.
In all seriousness, I'm working more than ever but actually enjoying not trying to fit in all the BS obligations that JW activity required for salvation and paradise that never comes. I've ran into so many JWs, at grocery stores, post offices, and everywhere between - one even tried to tell me it was a sign. I was like "how often do you come here" - He answered, ''once a week''. I replied ''I'm here at least two or three times a week, if this is a sign, then wow, someone with all power isn't really trying hard.''
Cofty is right - it's human nature to see patterns in what are otherwise natural coincidences at best. When you were ever on vacation for the first time in a new city, did you drive by a kingdom hall and notice it? How many other churches though did you drive by and notice that you still remember? Probably way more than kingdom Halls, but you never noticed them and certainly didn't remember them, because you didn't attach any meaning to them. It's simply what I call selective awareness.
You'll have it for a while - it won't ever be a sign. Eventually, you won't even notice it.
Now when I see those 25 top models that randomly appear out of nowhere looking for suntan lotion guy, the first thing I'm going to say when that happens is - "you're in luck - there's a town about 5 miles that way, I'm sure you'll find some guys there." Then I'll think to myself, "man - some day I'll get my break, I just gotta keep my eyes open."
