Answer:

Just as in any other plane, it's the wings that produce the lift that keeps a glider airborne. In a powered plane the engine pulls you forward to generate airflow over the wings. A glider achieves the same effect by flying slightly downhill all the time. In modern gliders the downhill angle needed is very small indeed.
