Acts 2:1–41 Pentecost: The Holy Spirit Comes and the Church Begins

The Ten Signposts of the Bible

CAMDE—400—CALY

Creation. Abraham. Moses. David. Elijah. 400. Christ.  APOSTLES. Letters. Yet-to-Come.

Jesus ascended to heaven, but before leaving, he told the apostles to wait in Jerusalem for the promised Holy Spirit. The apostles, along with 120 people, met in the upper room where Jesus had celebrated the Passover with his disciples. It was a spacious room in a large home, likely owned by John Mark's parents. On the day of Pentecost, observed fifty days after the Passover, “they were all together in one place” (Acts 2:1). 

Pentecost was a mandatory Jewish celebration, also called the “firstfruits.” Its purpose was to recognize God’s provisions for his people. Worshipers brought the firstfruits of the barley harvest as an offering to God. 

On the day of Pentecost, “suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting” (Acts 2:2). Along with this gale-force wind, each person saw tongues or groupings of fire come down and rest on each person (Acts 2:3). This was accompanied by all those present being filled with the Holy Spirit and speaking other languages that the Holy Spirit empowered them to speak (Acts 2:4). 

Because it was Pentecost, devout Jews “from every nation under heaven” had gathered in Jerusalem to celebrate God’s goodness. When they heard the followers of Jesus speaking to them in their own languages, Luke says the crowds were “bewildered,” “amazed,” and “astonished.” They could not understand how Galileans—who were not known for their intellectualism—were speaking languages from around the world (Acts 2:5–11). Many wondered how this was possible and what it meant, while others concluded that the disciples were drunk (Acts 2:12–13). 

Standing with the other eleven apostles, Peter addressed the crowd: “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” (Acts 2:14–15). He then quoted three Old Testament passages to show his Jewish audience that what they were witnessing—the coming of the Holy Spirit— had been part of God’s plan all along. 

First, Peter quoted Joel 2:28–32, where God promised to pour out his Spirit in the last days and that his servants would prophesy, just as the apostles were doing. Joel’s prophecy ends with this great invitation: “And it shall come to pass that everyone who calls upon the name of the Lord shall be saved” (Acts 2:21). 

Peter explained that this promise was being fulfilled before their very eyes. Jesus of Nazareth came demonstrating “mighty works and wonders and signs” (Acts 2:22). But he was “crucified and killed by the hands of lawless men” (Acts 2:23). This was all in accordance with the "definite plan and foreknowledge of God” (Acts 2:23). But death could not hold him! God raised him back to life! (Acts 2:24). 

Peter then turned to Psalm 16:8–11, where David declared that God would “not abandon [his] soul to Hades, or let [God’s] Holy One see corruption” (Acts 2:27). Peter reminded his audience that David died and was buried, “and his tomb is with us to this day” (Acts 2:29). However, David, “being . . . a prophet,” knew God had promised that one of his descendants would be on his throne.^[1] 

Peter explained that David’s words about one whose soul would not be abandoned to Hades and whose body would not decay was a prophecy “about the resurrection of the Christ” (Acts 2:31). He continued, “This Jesus God raised up, and of that we all are witnesses. Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this that you yourselves are seeing and hearing” (Acts 2:32–33). 

In his final Old Testament proof text, Peter quoted Psalm 110:1 to show that David had not ascended into heaven. In this passage, the Lord (Yahweh God) spoke to David’s Lord—the Christ—and said, “Sit at my right hand, until I make your enemies your footstool” (Acts 2:34–35).

Then Peter got straight to the point, declaring, “Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified” (Acts 2:36). 

Those who heard Peter realized that Jesus was truly the Messiah. “Cut to the heart,” they asked, “...What shall we do?” Peter told them to repent — to turn from their sins and former way of thinking— and be baptized. Baptism did not save them; rather, it was an outward expression of their inward trust in Jesus. Through baptism, they publicly identified with Jesus as they received forgiveness for their sins and the gift of the Holy Spirit (Acts 2:38).

Peter recognized that God was at work, calling people to himself, and he kept proclaiming the good news. Luke says, “And with many other words [Peter] bore witness and continued to exhort them, saying, ‘Save yourselves from this crooked generation.’ So those who received his word were baptized, and there were added that day about three thousand souls” (Acts 2:40–41). 

Just imagine-three thousand people responded to Peter’s sermon and put their trust in Christ! In a single day, the church was born and already flourishing!

Read and reflect on Acts 2:1–41: The crowd was “cut to the heart” and asked, “What shall we do?” Where is the Holy Spirit convicting you to turn from an old way of thinking or living and follow Jesus more fully?

Talking to God: Are you responding to the Spirit’s conviction?
