If you were raised as a Christian, you were taught that if you believed in any other god, you were a sinner, and would go to Hell. As a Wiccan, this is not so. First of all, Wiccans do not believe in an all- good, and an all-evil entity. There is no eternal struggle between Heaven and Hell. As a matter of fact, neither of them exist. We belive that good and evil reside withing everyone and everything, including the God and the Goddess.
You may be wondering, 'since there is no Heaven or Hell, what happens when I die?'. As a wiccan, you will see that there is a life cycle which every living thing will follow. It is born, grows old, dies, and is born again. This is also true for humans, after all, what makes us different from plants and animals. When you die, we do not go to one final place for the rest of eternity, but, rather, we are reborn into this world, to experience it in a new way. What happens when we have experienced this world in as many possible ways as possible? Who's to say? No-body can honestly tell you that they KNOW what will happen. Perhaps we are sent to another world/planet/ plane/etc., or perhaps we are blessed with the joy of spending the rest of time directly with the All. Until that time comes, we will never know, and when we do know, the chances are that we will either not be able to, or will not want to tell those still in this world the answers. Why would you want to ruin the surprise? And besides, if we were meant to know what happened, we would.
