I got lucky in that I was raised in the Reform tradition of Judaism so there wasn't really a whole lot of God talk. We focused more on life here rather than the hereafter and Judaism doesn't really have a conclusive answer on the afterlife decision anyway. So I sort of went along with the God part and had rabbinic school as a backup option throughout high school and have sort of distanced myself from it since then. My parents don't like to talk about it much, but I highly doubt that my dad believes in God (mom is a Jewish convert from Catholicism and has expressed extreme discomfort when I've even hinted at agnosticism so that's a whole other story).

To answer your questions, I never really talked to God at all and always assumed everyone else was faking it too. Regarding the afterlife, I look at it as an adventure either way and I'd rather not know what happens next.

So in my perspective, faith is for shaping your behavior in the here and now and making this time we have as fulfilling as possible. Some people use it that way, others don't need it as a guideline.
