From the Rabbis of the early Talmudic age I learned that there is never a last word on God. There's, you always continue to question.

I had tried, as I thought as a nun, to open myself to God and God seemed totally uninterested in me. The heavens remained closed and opaque.

God is not another being; we are talking about something much more profound.
