However, if the person is God, as is the Holy Spirit, then He can perform these functions in the same way as the Father and the Son. The Watchtower does admit that there are Bible passages that speak of the Holy Spirit in personal terms. Personification is the attributing of personal characteristics to inanimate objects for effect. They fail to understand that personifications are used for a specific purpose in writing. An author will use a personification to drive home a point vividly.
Death is personified by the word reign.
An impersonal object such as death cannot actually perform action such as reign. The answer is that death is described as being absolute and complete in a person's life. When a king reigns, his edicts are taken as absolute, with no questions asked. Death is colorfully described by likening it to the power of a king. When death speaks, its rule is final, no questions asked.
