In this message, Dave Bruskas walks through Peter’s sermon at Pentecost to help us better understand who Jesus is and why his life, death, and resurrection matter. The sermon shows that while God was at work through Jesus, our sin made the cross necessary. When the crowd realizes this, they ask what to do next, and Peter calls them to repent, be baptized, and follow Jesus. For us today, the invitation is to keep turning to Jesus, enjoy the presence of the Holy Spirit, and live as worshipers and witnesses.
