Today is Pentecost Sunday - a day whose significance some of us have heard about, and others are unfamiliar. Pentecost is the final episode of the Jesus event. As significant as Christmas and Easter are, without the coming of the Holy Spirit - the event of Pentecost - there would be no book of Acts. Without the Holy Spirit, this church wouldn't exist. Without the Holy Spirit there would be no New Testament to read. The Holy Spirit doesn't overshadow the history-changing arrival of Jesus Christ, but instead solidifies Jesus Christ as Lord.
