What makes the Church unlike any other organization in the world? In this first message of "The Origin of the Church" series, we go back to the day of Pentecost in Acts 2, when the Holy Spirit descended on 120 believers and everything changed. We'll unpack Peter's sermon, the prophecy of Joel that he quotes, and what it means that the Spirit's ministry moved from the Old Testament temple to the New Testament Church. Along the way, we look at what actually makes a church a church, what it means to be a Christian, and an honest question for you: what does the church really mean to you?
