Observation
Observation answers the question: “What does the text say?” It’s slowing down and noticing the details before determining what the text means. To observe, first ask who, what, when, where, why, and how questions about the passage you’re studying. (e.g., “Who is speaking, being spoken to, or might be nearby listening?”) Every answer should be backed up by a verse reference, and your answers shouldn’t be guesses or inferences—they’re simply observations. Answering these questions can also mean reading the passage slowly, looking for key words, repetition, comparison, contrast, relationships, general/specific usage, word order, patterns, or any other details.
Acts 2:1-21
Chapter 2
The Coming of the Holy Spirit
1 When the day of Pentecost arrived, they were all together in one place. 2 And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3 And divided tongues as of fire appeared to them and rested 1 2:3 Or And tongues as of fire appeared to them, distributed among them, and rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
5 Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. 6 And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. 7 And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? 8 And how is it that we hear, each of us in his own native language? 9 Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, 11 both Jews and proselytes, Cretans and Arabians—we hear them telling in our own tongues the mighty works of God.” 12 And all were amazed and perplexed, saying to one another, “What does this mean?” 13 But others mocking said, “They are filled with new wine.”
Peter's Sermon at Pentecost
14 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. 15 For these people are not drunk, as you suppose, since it is only the third hour of the day. 2 2:15 That is, 9 a.m. 16 But this is what was uttered through the prophet Joel:
17
‘And in the last days it shall be, God declares,
that I will pour out my Spirit on all flesh,
and your sons and your daughters shall prophesy,
and your young men shall see visions,
and your old men shall dream dreams;
18
even on my male servants and female servants
in those days I will pour out my Spirit, and they shall prophesy.
19
And I will show wonders in the heavens above
and signs on the earth below,
blood, and fire, and vapor of smoke;
20
the sun shall be turned to darkness
and the moon to blood,
before the day of the Lord comes, the great and magnificent day.
21
And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.’

Introduction to Acts
Timeline
Author and Date
Acts is a sequel to the Gospel of Luke. Both were written by Luke, a physician who traveled with the apostle Paul. Acts ends with Paul under house arrest, awaiting trial before Caesar, c. A.D. 62. Many scholars assume Acts was written then because it does not record Paul’s defense, release, and further gospel preaching.
Theme
The Holy Spirit empowers believers to declare the gospel among both Jews and Gentiles. In doing so they establish the church. The church is the fulfillment of God’s promises from the beginning of time.
Purpose
Luke’s purpose for writing his Gospel (see Luke 1:3–4) applies to Acts as well: to give an “orderly” account of the early church after Christ’s resurrection. Dedicating the two-volume work to Theophilus, Luke wanted him to have “certainty” about what he had been taught.
Key Themes
Acts tells of the witness of the early church to the truth of the gospel—a theme first introduced in 1:8:
- The witness is worldwide—Judea, Samaria, the “end of the earth” (1:8).
- The witness includes all kinds of people (chs. 2–5; 10:1–11:18; 14:8–18; 16:11–15, 25–34; 17:22–31).
- God guides the church’s witness (4:5–22; 23:12–22; 24:1–23; 27:21–26).
- Faithful witnesses must be prepared to suffer and even die because of their testimony to Christ (5:41–42; 7:54–60).
- The Holy Spirit empowers the witness (1:8; 2:1–13; 8:17; 13:2–12; 19:6).
- Effective witness demands unity in the church (2:42–47; 4:32–37; 5:12–14).
- Jesus’ resurrection is a key part of the witness (1:22; 2:22–36; 17:30–31).
- Acceptance of the message depends both on human response and on God’s sovereign will (2:47; 11:18; 13:48).
- The witness to the gospel calls for a response (26:27–29). It requires repenting of one’s sins in the name of Christ. This brings forgiveness of sins (e.g., 2:38).
- Witnesses must always maintain integrity before the world (18:12–15; 23:29; 25:18; 26:31–32).
- Christian witnesses continue the ministry that Christ “began” (1:1).
- Faithful witness can bring great results (4:4; 13:48–49; 17:4; 28:30–31).
Outline
- Preparation for Witness (1:1–2:13)
- The Witness in Jerusalem (2:14–5:42)
- The Witness beyond Jerusalem (6:1–12:25)
- The Witness in Cyprus and Southern Galatia (13:1–14:28)
- The Jerusalem Council (15:1–35)
- The Witness in Greece (15:36–18:22)
- The Witness in Ephesus (18:23–21:16)
- The Arrest in Jerusalem (21:17–23:35)
- The Witness in Caesarea (24:1–26:32)
- The Witness in Rome (27:1–28:31)
The Setting of Acts
Fact: Who wrote Luke?
Who wrote Luke? Luke wrote both this Gospel account and Acts. He probably traveled with Paul and participated in his ministry (see Col. 4:14; 2 Tim. 4:11; Philem. 24). Luke was also a physician (Col. 4:14).
Fact: The speeches in Acts
The speeches in Acts are an important part of Luke’s historical account. They make up nearly a third of the book. Ten of these are extended speeches: three by Peter, one by Stephen, and six by Paul.
Fact: Ananias
Ananias. There are three different men named Ananias in the book of Acts (see 5:1; 9:10; 24:1). The Ananias who was apparently the first believer to welcome Paul after his conversion is a positive example of obedience to the Lord (9:10–19).
Fact: What is “the Way?”
What is “the Way?” In Acts, “the Way” appears six times (9:2; 19:9, 23; 22:4; 24:14, 22). People who belonged to the Way were followers of Christ. It means the way of salvation (16:17) and/or the true way of life in relation to God (see 18:25–26).
Fact: What happens next?
What happens next? Acts ends with Paul serving Christ from within a Roman prison. During this time, he wrote Ephesians, Philippians, Colossians, and Philemon. According to the church historian Eusebius, Paul was released, then arrested a second time, and eventually martyred in Rome.
Fact: The Feast of Weeks
The Feast of Weeks is known in the NT as Pentecost (Acts 2:1). It was a celebration honoring the Lord as provider of all crops and as the One who deserved the firstfruits of those crops.
Fact: Nations at Pentecost
Nations at Pentecost. The list of nations in 2:9–11 covers most of the first-century Roman world. Many Jews who lived outside Palestine traveled to Jerusalem to celebrate Pentecost, an annual feast. The Holy Spirit enabled them to hear the disciples speak in their own languages (2:6).
Fact: Jesus knows us
Jesus knows us. Jesus knew that, in his hour of greatest need, Peter would deny him (22:34). He also knew that Peter would repent and go on to be a great leader in the church (v. 32; see Acts 2:14–41). As Paul declared, “The Lord knows those who are his” (2 Tim. 2:19).
The Setting of 1 Timothy
c. A.D. 62–64
Paul likely wrote 1 Timothy during a fourth missionary journey not recorded in the book of Acts. Writing from an unknown location, Paul wrote to Timothy at Ephesus to instruct him on how to lead the church there. Ephesus was a wealthy and highly influential port city in the Roman province of Asia, renowned for its temple of Artemis (Diana).
The Setting of 2 Timothy
c. A.D. 64–67
Paul probably wrote 2 Timothy during a second imprisonment in Rome following a fourth missionary journey that is not recorded in Acts. Expecting that death would come soon, Paul wrote this “farewell” letter to Timothy, who was at Ephesus, urging him to stand firm and asking him to come for one final visit.
The Setting of Titus
c. A.D. 62–64
Paul likely wrote Titus during a fourth missionary journey not recorded in the book of Acts. Writing from an unknown location, he instructed Titus in how to lead the churches on the island of Crete. The churches there had apparently been founded by Paul.
Nations at Pentecost
c. A.D. 30/33
Pentecost attracted Jews from all over the world to Jerusalem to celebrate the annual festival. Those who heard the apostles’ message in their native languages at Pentecost came from various regions within the two great competing empires of the day—the Roman Empire and the Parthian Empire—with Jerusalem near the center.

Luke
Luke was a doctor (Col. 4:14) and a faithful companion of Paul, accompanying him on several journeys. He was with Paul throughout his two-year imprisonments in both Caesarea and Rome. He is the author of the Gospel bearing his name and the book of Acts, where he records his travels with Paul. Little else is known about Luke. Most scholars believe that he was a Gentile. This is based in part on the fact that Paul does not include Luke among the “men of the circumcision” who were his fellow workers (Col. 4:10–11). How Luke came to know Christ is not revealed, though his thorough acquaintance with the OT suggests that he may have been a “God-fearer” like Cornelius before becoming a Christian. (Acts 21:1–8)
Acts 2:1 Pentecost was the second of the annual harvest festivals. It came 50 days after Passover. All most likely included the 120 assembled in the upper room (1:15).
Fact: The Feast of Weeks
The Feast of Weeks is known in the NT as Pentecost (Acts 2:1). It was a celebration honoring the Lord as provider of all crops and as the One who deserved the firstfruits of those crops.
Acts 2:3 The divided tongues as of fire were not literal flames, but they looked enough like fire that this was the best description. “Fire” in the OT often indicates God’s presence. It also symbolizes his holiness and purity (Ex. 3:2; 19:18; Isa. 4:5).
Acts 2:4 Filled with the Holy Spirit fulfills what Jesus promised (see notes on 1:5; 1:8). This marked the beginning of the new covenant age, which will last until Jesus returns. speak in other tongues. The word translated “tongues” can also be translated “languages,” and that is the sense here. as the Spirit gave them utterance. See 10:45–46; 19:6.
Acts 2:5 The crowd’s presence indicates that the setting is the temple grounds. This was the only place in Jerusalem that could accommodate more than 3,000 persons (v. 41). The fact that they were dwelling in Jerusalem suggests that both Jewish pilgrims and local residents were present.
Nations at Pentecost
c. A.D. 30/33
Pentecost attracted Jews from all over the world to Jerusalem to celebrate the annual festival. Those who heard the apostles’ message in their native languages at Pentecost came from various regions within the two great competing empires of the day—the Roman Empire and the Parthian Empire—with Jerusalem near the center.
Acts 2:9–11 The list of nations covers most of the first-century Roman world, particularly areas where Jewish communities existed. At Pentecost the Christians start their worldwide witness. At this point the converts were mainly Jewish. The only Gentiles at Pentecost were proselytes, Gentiles who had become full converts to Judaism.
Acts 1:1–2:13 Preparation for Witness. Acts opens with the account of the Spirit’s descent at Pentecost. Chapter 1 relates the preparation for that event, which occurs in 2:1–13.
Acts 2:17 The last days began at Pentecost (see Heb. 1:2). They will continue until Christ’s return. Most rabbis believed the Spirit stopped speaking through human prophets with the last of the OT prophets. Joel’s prophecy of an outpouring of the Spirit on all flesh was understood as referring to a new messianic age. daughters. The women in the upper room participated in the gift of the Spirit at Pentecost, further confirming Joel’s prophecy.
Equivalent Expressions for the “Last Days”
The “last days” (the day of salvation, 2 Cor. 6:2) have already come but the “last day” (the day of salvation and wrath, 1 Thess. 5:1–11) has not yet arrived. The following are equivalent expressions for the “last days” (the period of time between Jesus’ death and resurrection and the final judgment).
| “the last days” | Acts 2:17; 2 Tim. 3:1; Heb. 1:2; James 5:3 |
| “the last hour” | 1 John 2:18 |
| “the last time” | Jude 18 |
| “the last times” | 1 Pet. 1:20 |
Acts 2:19–21 The darkened sun and bloody moon, whether literal or symbolic, indicate the end of the earth. Peter included the full prophecy even though not all of it was yet fulfilled at this time. everyone who calls upon the name of the Lord shall be saved (Joel 2:32). The “name of the Lord” that saves is Jesus (see Acts 2:36; see 4:12), which affirms his deity.
Observing Acts 2:1-21
When we study the Bible, the first step is to pray for the Spirit to guide our study and to open our minds and hearts to see, understand, and respond to his truth. Make it a regular practice to pray before starting Join The Journey each day.
After prayer, the next step is observation. Observation means slowing down and noticing what the text actually says—before we interpret or apply it. In Acts 2:1-21, Luke describes the dramatic day of Pentecost when the promised Holy Spirit was poured out.
Here are a few observations you might make:
- The disciples were gathered together “in one place” when the Spirit came (v. 1).
- Suddenly, supernatural signs appeared—sound, wind, and fire—all pointing to God’s presence and power (vv. 2-3).
- Every disciple was filled with the Holy Spirit and began speaking in other languages (v. 4).
- People from many nations heard the gospel in their own languages (vv. 5-11).
- Peter stood up and explained what was happening through Scripture (vv. 14-21).
Observation is about seeing what’s in the text—not rushing to meaning or interpretation. Acts 2 gives us a timeline-like sequence of events and charting it helps us really see the flow of the story.
Observe Acts 2:1-21
- Make a simple timeline of the events in Acts 2:1-21. Write down what happened first, second, third, and so on.
- List every group of people mentioned—who was present, and what did they do?
- Underline or circle the repeated words or images (for example: “tongues,” “filled,” “Spirit,” “prophesy”).
Take your time with these details. The goal is to train your eyes to slow down and notice the sequence of events—don’t rely on previous knowledge of the passage or rush to conclusions. Act like a detective: What’s happening in this story? Who’s present? Why are they doing what they’re doing?
Prayerfully review your timeline and list of observations. How do you see God highlighting his power, his presence, or his Word? Pray and ask God if there’s anything he wants you to notice, then write a prayer of response. Thank God for pouring out his Spirit and ask him to help you live aware of his power at work in you today.
