John 14: 16, 26
Is it not strange that so much is made of the Holy Spirit in the New Testament and so little in Christian writings supposed to be based upon the New Testament? One of the church fathers, in a treatise on the Trinity written in the third century, devotes to the Holy Spirit but six pages of a book 140 pages in length. While defending the deity of the Spirit, he yet says twenty times as much about the Father and the Son as about the Spirit.
I think it would be only fair to admit that there is more in the New Testament about the Son than about the Spirit, but the disproportion is surely not so great as in the writings referred to above, and certainly the all but total neglect of the Spirit in contemporary Christianity cannot be justified by the Scriptures. The Spirit appears in the second verse of the first book of the Bible and in the last chapter of the last book of the Bible, as well as hundreds of times between the first and the last.
It is not, however, the frequency of the Spirit’s mention in the Bible or in other writings that matters most, but the importance attached to Him when He is mentioned. And there can be no doubt that there is a huge disparity between the place given to the Spirit in the Holy Scriptures and the place He occupies in popular evangelical Christianity. In the Scriptures the Holy Spirit is necessary. There He works powerfully, creatively; here He is little more than a poetic yearning or at most a benign influence. There He moves in majesty, with all the attributes of the Godhead; here He is a mood, a tender feeling of good will.
