To go from faith to no faith is painful.
You don't have to go from faith to faith. You don't have to lose faith. Finding out that Jehovah is a false god and that the JWs are a cult, doesn't mean you necessarily lose all faith. True, some do lose all faith, for varied reasons, but so many of us don't. Especially is this true for those who were not born, nor raised in the JWs.
