The apocalyptic truth is here presented by means of different symbols. The symbolism of the vision in the opening verses of Revelation twenty include the angel coming down from heaven, with the key and the great chain he has in hand, the bottomless pit, and the shutting up of Satan, and the sealing of the pit over his head. There cannot be any doubt that this is to be understood symbolically, and, therefore, dare not be interpreted as signifying that the devil shall be literally confined in a pit. For Satan who is a spirit is not, and cannot be bound with a steel chain, locked up by means of a key, and sealed with any physical seal. Nor is it difficult to understand the symbolism of this apocalyptic vision, and to determine what is the idea expressed by it. It means that the devil is bound by the decree of him that sitteth on the throne, so that he is restrained from accomplishing his purpose. The question though is, does the passage teach that Satan is completely bound, so that he is doomed to absolute inactivity, or is this idea of the restraint put upon him presented as limited to a certain aspect of his evil purposes? This questioned is answered here too.
