These views of the Spirit's administration in the assemblies of believers, and of his manifestation in all believers for common profit, fully accord with Scripture teaching (1 Cor. 12; Rom. 12; Eph. 4; etc.). Were such views practically held in the church today, a radical revolution would be wrought and a revival of apostolic faith and primitive church life would inevitably follow. No one subject is perhaps more misunderstood, or less understood, even among professed believers, than the person, offices, and functions of the Spirit of God. John Owen, long since, suggested that the practical test of soundness in the faith, during the present gospel age, is the attitude of the church toward the Holy Spirit. If so, the great apostasy cannot be far off, if indeed it is not already upon us, for there is a shameful ignorance and indifference prevalent as to the whole matter of his claim to holy reverence and obedience.
