Today: [Acts 02: Part 2] What Does this Mean and what Must We Do? In Part two of our study of Acts 2, we consider Peter's great Pentecostal sermon. The resurrection figured prominently in this declaration, and Peter emphasized the speaking in other tongues as the singular evidence of the resurrected Christ. In response to the power of this message and this experience the people present cry out "what does this mean?" and "what must we do?" The result was 3000 souls kickstarting the fledgling early church.
