"A doctrine has practical value only as far as it is prominent in our thoughts and makes a difference in our lives. By this test the doctrine of the Holy Spirit as held by evangelical Christians today has almost no practical value at all. In most Christian churches the Spirit is quite entirely overlooked. Whether He is present or absent makes no real difference to anyone. Brief reference is made to Him in the Doxology and the Benediction. Further than that He might as well not exist."
