Acts 2:1-4, 14-15, 22-24 ESV
When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and rested on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance. But Peter, standing with the eleven, lifted up his voice and addressed them: "Men of Judea and all who dwell in Jerusalem, let this be known to you, and give ear to my words. For these people are not drunk, as you suppose, since it is only the third hour of the day. "Men of Israel, hear these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs that God did through him in your midst, as you yourselves know— this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. God raised him up, loosing the pangs of death, because it was not possible for him to be held by it.

Our mission is the mission of God, of Jesus. Understanding our roles will be helpful for us. The movement of the gospel moved throughout Judea, then to the next state, Samaria. Finally to the ends of the earth.
Wimps into witnesses
We are all wimps in sharing our faith. We do not have boldness in sharing our faith. We see Peter transformed into a powerful witness by the Spirit. Peter denied Jesus. He hid when Jesus was crucified, in great fear for his life.
Turns crowds into communities
The church is a motley crew of people. People who would not usually get along or like each other become a fellowship. A group of people who don't speak the same language and are from different places come together to celebrate a festival. When the Spirit comes, the people, the motley crew comes together into a mission-centered community.
Turns cities into saturation points
Jerusalem had 600,000 people. On pentecost, 3,000 became followers. Later 5,000 became believers. In meeting at homes, this would mean that there were at least two hundred house churches in the city of Jerusalem in a very short period. There was access to the gospel throughout the city in a very short period of time. The Spirit desires to saturate the city with Christians.
