Pentecost is at the core, or the heart of what the Church is built upon. The principles that were established there made the Church healthy enough to be able to reach out beyond Jerusalem and to spread to the rest of the world. Without those core principles there would be no Church today, that is why we must learn from them, in this sermon, we take a look at what a few of those were.  Acts 2:42-47 I. Commitment. (42-43), II. Care. (44-45), III. Community. (46-47).
