The Old Testament period may be called the Age of the Father; the period covered by the Gospels, the Age of the Son; from Pentecost until the second advent of Christ, the Age of the Spirit. All matters pertaining to the doctrine of the Holy Spirit should, therefore, be of special interest to us who live in this age of special privilege. Yet how ignorant is the average Christian concerning matters pertaining to the Spirit. The Christian church today needs to heed Paul's exhortation: "Now concerning spiritual gifts (or, perhaps better, "matters pertaining to the Spirit"), I would not have you ignorant." May it not be that the reason why the sin against the Holy Spirit is so grievous is because it is a sin committed in the light and with the knowledge of the clearest and fullest revelation of the Godhead. We cannot, therefore, afford to remain in ignorance of this all-important doctrine. I. THE PERSONALITY OF THE HOLY SPIRIT. It seems strange that it should be necessary to discuss this phase of the subject at all. Indeed, in the light of the last discourse of the Master (John 14-16), it seems superfluous, if not really insulting. During all the ages of the Christian era, however, it has been necessary to emphasize this phase of the doctrine of the Spirit (cf. Arianism, Socinianism, Unitarianism). 1. WHY IS THE PERSONALITY OF THE HOLY SPIRIT QUESTIONED? a) Because, as Contrasted with the Other Persons of the Godhead, the Spirit Seems Impersonal. The visible creation makes the personality of God the Father somewhat easy to conceive; the incarnation makes it almost, if not altogether, impossible to disbelieve in the personality of Jesus Christ; but the acts and workings of the Holy Spirit are so secret and mystical, so much is said of His influence, graces, power and gifts, that we are prone to think of Him as an influence, a power, a manifestation or influence of the Divine nature, an agent rather than a Person. b) Because of the Names Given to the Holy Spirit. He is called _breath, wind, power._ The symbols used in speaking of the Spirit are _oil, fire, water,_ etc. See John 3:5-8; Acts 2:1-4; John 20:22; 1 John 2:20. It is not strange that in view of all this some students of the Scriptures may have been led to believe, erroneously of course, that the Holy Spirit is an impersonal influence emanating from God the Father. c) Because the Holy Spirit is not usually Associated with the Father and the Son in the Greetings and Salutation of the New Testament.
