The Spirit-Filled Church: Witness in Word and Life Acts 2:14–47 Josiah Friesen – April 19, 2025

A Spirit-filled church doesn't just proclaim a risen Jesus — it puts his resurrection on display through the kind of community that can't be explained apart from him.

Sermon Summary

Josiah opened by drawing two threads from Acts 1–2: the church is called to be Jesus' witnesses, and that witness requires the Holy Spirit. The witness itself has two inseparable dimensions — proclamation and community. Peter's sermon in Acts 2:14–41 proclaimed that Jesus is the promised Messiah, he died for sin, God raised him, and now he calls everyone to repent, be baptized, and receive the Holy Spirit. The church does this every week. (And Josiah reminded us that May 3 there is a baptism class for anyone ready to take that first step, with a baptism service planned for May 31.)

The second half of the sermon focused on Acts 2:42–47 and the community that the gospel produces. Luke's description of the early church was meant to not only an accurate picture of what happened, but an aspirational goal for churches to follow. He gave the marks that should be true of every church: devoted to teaching (the Bible), fellowship, meals and communion, and prayer. But Luke also showed how the Spirit-filled community showed so much more of the gospel of Jesus by sharing possessions, meeting daily, eating together with joy. Josiah named it plainly: a Spirit-filled community is itself evidence for the resurrection. The church's common life either confirms or contradicts what it preaches. And that community life isn't something we manufacture through more effort — it is the natural overflow of full surrender to Jesus Christ, by his Spirit.

Scripture Reading

Read Acts 2:37–47 aloud as a group.

Main Discussion Questions

  • God Revealed: What evidence did the church have that God was dwelling among them by his Holy Spirit? What dynamics in this picture of the early church can only be attributed to him? 

  • Humanity Mirrored: Francis Chan has observed gangs demonstrate deeper community than most North American churches. What does this tell us about our default settings as human beings — and how hard it is to actually be a devoted, generous, everyday people?

  • Gospel-Centered Vision: Josiah said the church's common life is "its first and most important witness." As a group, define what the good news of Jesus is, and then how that good news shapes the way we live life together.

  • Transformed Living: Josiah named four marks of the Acts 2 community: devoted to the fellowship, generous to each other, lived out their faith everyday, and were growing as a church. Which of these most challenges the way you actually live right now, or which of these has made the biggest difference in your life?

  • Sharing and Witness: Who have you had the chance to invite to church? How did they respond when they met the Spirit-filled community of Jesus? How does the church help you live out your faith day to day?
