On this Pentecost Sunday, we review the facts that being filled with the Holy Spirit was a normative experience for the early church, that it is just as important today as it was 2000 years ago, and that the Holy Spirit is just as available today as He was on the day of Pentecost. In this sermon Rev. McMahon reviews the marks of this experience, how to receive the Holy Spirit, and why many who had this experience at conversion have drifted away.
