The Holy Spirit is Our Refiner When the Spirit came upon the 120 disciples in the upper room on the Day of Pentecost, He was manifested in primarily two ways. (1) The sound of a rushing wind and (2) flames of fire that miraculously appeared on each person's head. We do not know the exact nature of this fire; it obviously was not physical fire or it would have burned everyone's hair! it was most likely the visual manifestation of the Spirit's presence. But most assuredly of God.
Are you willing to allow God to purify you, even in hidden areas?
