God endowed him with an imperishable personality. He is a person who influences. A person is an intellectual being who is master of his own freely chosen activities. It does not matter whether he be of a spiritual nature, as God or the angels, or of a semi-spiritual nature, as man. The devil has intelligence and freewill. He can exert a spiritual influence suggestive of evil. Many people say that they do not believe in the devil. That is quite in keeping with his wishes. But Christ definitely warns us against the evil influence of Satan.
