Well, I suppose in some ways I was ready to believe. I was raised in an observant Jewish home. My experiences with Jewish life were very positive, and my parents and community were always encouraging with questions and explorations, and comparative religion in an extremely pluralistic fashion. So my experience of religion was not unduly oppressive, or rigid, or closed-minded, or unpleasant.
Nonetheless, as often happens, when I was a teenager,I went through a period of extreme skepticism and rebellion, which translated into being agnostic to the point of atheism, and a near total lack of Jewish observance for some years. I actually wanted to believe in God, I just thought there was not enough reasoned evidence for me to do so, given that the good so often suffer and the evil so often prosper.
But I had a revelatory experience one Rosh Hashanah, when I was in my early twenties.
I can't really explain it. I had gone to services at the synagogue with my parents, because my mom insisted. But I was just standing there, not knowing what I was doing there, feeling vaguely hypocritical, when suddenly, it was as though someone had put a hand on my shoulder and said my name. I don't mean that literally, of course-- I didn't physically feel anything. But it felt like that. An extremely intense sensation of not being alone, of someone standing with me, almost like being in an embrace. And I got a distinct feeling, which wasn't literally like hearing a voice, but it was almost like hearing the echo of someone saying something. And if I had to roughly put into words what I thought it might have said, it would be, "Don't worry. It's going to be okay." And somehow, things just felt different after that. I knew there was a God. And it just didn't matter whether His existence was objectively, scientifically provable: that didn't seem relevant anymore.
So after that, I slowly began to observe and practice again. And I studied more, and began to read theology and philosophy, until I began to have some language to express what I felt about God. And then, in my thirties, I went to rabbinical school. Today I am a rabbi, married to another rabbi, and entirely comfortable being an observant, believing Jew.
