If we were to make all the decisions about what we need to learn then what need of the god or goddess?
Again, the may or may not be "real" beings, depending on your personal feelings towards the matter.
If you read my post, I don't believe in the God and Goddess as "real" beings. To me, the universe is real. When I pray to the God and Goddess, I'm actually praying to the universe. The God and Goddess just give me something that I can comprehend and direct my thoughts to with my small, human mind.
So, everything depends on your beliefs about things. That's one of the great things about Wicca: you aren't required to spout back dogma. God (or Goddess) isn't what some crusty old men tell you it is. It is what you believe, or don't believe. So, maybe there is and maybe there isn't a goddess or a god.
One of my favorite quotes from the movie Dogma is when the Muse says, "It's not important what you believe. It's just important that you believe something." Or something like that anyway...
