If you think everything happens for a reason and we have no control over our own futures, then you believe in predestination.
In religious terms, predestination is the belief that everything that happens has already been determined by God — He's got a master plan, and there's no deviating from it. It's kind of a depressing and extreme world view that doesn't leave much room for making personal choices. Predestination is related to the concept of omniscience — meaning God knows everything. If you're a strong believer in free will, then you'll probably hate the idea of predestination.
