What is a summary of the book of Acts?

from the old testament

• The book of Acts is not found in the Old Testament.

from the new testament

• The book of Acts is the first book about church history. It is the second book of Luke, beginning where the Gospel of Luke ends: Jesus’ ascension. In the Acts ascension account, Jesus told the disciples, “you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth” (Acts 1:8). That is effectively the purpose statement of Acts, as it shows how the church starts in Jerusalem when the Holy Spirit came (Acts 2:1–4) and how it quickly spread first in Jerusalem, then the surrounding regions, and finally deep into Gentile territory.
• There are many events and characters in the book of Acts. However, it can be summarized as the story of two men (Peter and Paul) and their work in the early church.
• Peter is the focus of the first third of this early church history. After the church started, he gave the first sermon (Acts 2:14–36), which led to the first 3,000 people being saved (Acts 2:41). The church grew every day (Acts 2:47).
• A key event in Peter’s ministry was a vision in which God showed Peter that Gentiles were included in God’s plan. He used the vision of foods previously considered unclean, telling Peter to “eat” them (Acts 10:9–16). This was followed by the first Gentile convert arriving at Peter’s door and Peter preaching the gospel to him and a group of other Gentiles (Acts 10:17–33). When the Holy Spirit came on those Gentiles, as He had at Pentecost with the Jewish disciples, they realized they had the same salvation (Acts 10:44–48).
• The rest of Acts focuses on Paul. It began with him first participating in Stephen’s death (Acts 7:58; 8:1) and pursuing the legal right to capture and persecute more Christians (Acts 9:1–2). On his way to obtain the necessary paperwork, Jesus blinded him (Acts 9:3–9) and then called him to take the gospel to the Gentiles (Acts 9:15), an event Paul later described in prison (Acts 26:17–18).
• From that point, Paul began going to the Gentiles, with most of Acts detailing his three missionary trips (Acts 13:1–14:28; Acts 15:36–18:22; Acts 18:23–21:17). Those travels included other well-known figures such as Barnabas (Acts 13:2–3) and Silas (Acts 15:40). Luke also traveled with him, which is why Acts focuses to predominately on his ministry (e.g., Acts 16:10). Acts ends with Paul in a Roman prison (Acts 28:30–31).
• In addition to the general ministries of Peter and Paul, Acts also includes the first church council (Acts 15:1–21). It was needed because some Jewish converts were requiring Gentiles to obey the Mosaic Law. Both Peter and Paul were in attendance, with the final decision being, “we should not trouble those of the Gentiles who turn to God, but should write to them to abstain from the things polluted by idols, and from sexual immorality, and from what has been strangled, and from blood" (Acts 15:19–20). In short, they did not need to obey the various points of the Mosaic Law, but they did need to obey its heart of loving God and their neighbors by refraining from the sinful practices of the pagans.

implications for today

What started in Acts 2 continues to this day. Jesus’ church is growing, and the gospel is spreading.  However, the mission Jesus gave the church (Acts 1:8) is not finished. There are still parts of the earth that have never heard about Jesus. In other regions, there are so few Christians that even in those “reached” regions, most still don’t know anything about Jesus.

Does this mean that the church has failed in its mission? No. Rather, it highlights its enormity and the realities of spreading the Gospel. It also demonstrates the fierce opposition the Gospel faces through false teaching, false religions, persecution, and Satan’s work against the truth. However, it continues to progress because Jesus will not be stopped from building His church (Matthew 16:18). There will be a day when every nation, tongue, and tribe will have heard (Matthew 24:14; Revelation 7:9).

The spread is slow, but faithful men and women have continued pushing it forward. There are so many right now in places you’ve never heard about, quietly working. Not all of us are called to go to a far-off place, but we are all called to help. The missionary William Carey once quipped that we must either be going down into the well or holding the rope so others can go down. His point was that we all have a part to play in spreading the Gospel.

What part are you playing in Jesus’ mission? Not everyone is called to move across the world, but every believer is called to play a part—whether that means serving faithfully in your local church, sharing the gospel with the people around you, giving, praying, or supporting those who go. Start where God has placed you: use the gifts He has given you to serve His church (1 Peter 4:10; 1 Corinthians 12:4–7) and look for opportunities to share the gospel wherever you go. You don’t have to go everywhere—you just have to be faithful where God has placed you.
