In Acts 2 we left our heroes, the apostles and their friends, waiting in the courts of the temple. If that sounds like an introduction to a television serial it is only because this is the book where the action is -- the book of Acts. As the apostles and their friends waited in the temple courts, three amazing things happened: There was a sound like a great blast of wind which roared through the house where they were sitting, the porch of Solomon. There also appeared tongues of fire dancing upon the head of each of the one hundred and twenty believers, and they were all filled with the Holy Spirit and began to speak in other tongues, other languages, as the Spirit gave them utterance. That is the phenomenon of Pentecost, the beginning of the church of Jesus Christ the body of Christ; it was the birthday of the church.
