Satan

"The Holy Spirit was to glorify them who was to suffer in Jerusalem. But the false spirit that is in the world glorifies itself. It denies and treats with contempt Christ who suffered for us. Its own glory and honour is all this false spirit seeks, wholly upsetting the order of the divine dispensations. THe origins and source of all divine dispensations lay in the Father's love. The Son came to glorify the Father. He still says, 'I do not seek my own glory, but the glory of him that sent me'. The Son, having carried on the work of redemption, was now to be glorified with the Father. This is what he prayed for (John 17:1). So the Holy Spirit is sent, whose work it is to glorify the Son. But now a false spirit has come whose whole work is to glorify himself not Christ. By this we can know what sort of spirit this is that is in the world."
