When any local church, any company of believers associated for spiritual ends, fulfills the social conditions, — all of one accord in one place making the reception of the Holy Spirit their only business for at least ten days, Pentecost will be repeated in every essential particular. Their hearts will be purified by faith, and they will be endowed with a marvelous spiritual insight and courage and utterance.
It is not the law of the Spirit that His transfiguring power should decrease with the lapse of ages, nor with the spread of education and the growth of intelligence and culture. It is true that there is an intellectual pride with a pretense to culture which boasts that it has outgrown such so-called crudities as disfigured Christianity on the day of Pentecost. These over-wise philosophers insist that the doctrine that one personality, even though divine, can interpenetrate a human personality and consciously abide therein, violates all the known principles of mental philosophy and lays the foundation of various forms of fanaticism, in the end destructive of all morality and sound piety. Our reply to this is that the greater the value of a coin the greater its liability to be counterfeited. The highest possible experience for men dwelling in houses of clay is to be inhabited by God in the person of His Spirit. This is a mystery next to the incarnation of the Son of God in human form.
