Acts

The Book of Acts

​​​​

The Book of Acts was written by Luke, the same physician who wrote the Gospel of Luke. He wrote both books to a man named Theophilus to give an orderly account of everything that happened. Acts continues where the Gospel of Luke ends, showing how Jesus's followers spread His message across the world after He returned to heaven. This book covers approximately 30 years of early church history, from around 30 AD to 62 AD.

​

The Promise of the Holy Spirit

 

Acts begins with Jesus spending forty days with His disciples after His resurrection, teaching them about the kingdom of God. Before ascending to heaven, Jesus gave them this crucial promise: "But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth" (Acts 1:8, KJV). This verse provides the structure for the entire book, as we see the gospel spreading exactly as Jesus predicted.

Jesus then ascended to heaven while His disciples watched. Two angels appeared and promised that Jesus would return in the same way He left. This fulfilled what Jesus had told them earlier and gave His followers hope for His second coming.

​

The Day of Pentecost

 

Ten days after Jesus ascended, while 120 believers were praying together in Jerusalem, something extraordinary happened. On the Jewish festival of Pentecost, "suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance" (Acts 2:2-4, KJV).

This was the fulfillment of what the prophet Joel had predicted hundreds of years earlier: "And it shall come to pass afterward, that I will pour out my spirit upon all flesh" (Joel 2:28, KJV). Peter stood up and explained to the amazed crowd that they were witnessing this ancient prophecy coming true. He then preached the first Christian sermon, telling the people that Jesus, whom they had crucified, was both Lord and Christ.

​

Peter's message was powerful. He explained that Jesus's death was part of God's plan and that David had prophesied about Jesus's resurrection when he wrote, "For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption" (Psalm 16:10, KJV). Peter declared that David was speaking about Jesus, who God raised from the dead. When the people asked what they should do, Peter told them, "Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost" (Acts 2:38, KJV). About 3,000 people believed and were baptized that day.

 

The Early Church in Jerusalem

 

The new believers devoted themselves to the apostles' teaching, fellowship, breaking bread together, and prayer. They shared everything they had with one another, and "the Lord added to the church daily such as should be saved" (Acts 2:47, KJV). This shows us what the first church looked like: a community united by faith in Jesus, generous with their possessions, and growing as people encountered the risen Christ.

​

Peter and John healed a man who had been lame from birth, using this miracle to preach about Jesus. Peter told the crowd, "Ye are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, And in thy seed shall all the kindreds of the earth be blessed" (Acts 3:25, KJV). This refers back to God's promise to Abraham in Genesis 22:18, showing that Jesus was the promised seed through whom all nations would be blessed.

​

The religious leaders arrested Peter and John, but this did not stop the church from growing. When threatened and told to stop preaching about Jesus, Peter and John responded, "Whether it be right in the sight of God to hearken unto you more than unto God, judge ye. For we cannot but speak the things which we have seen and heard" (Acts 4:19-20, KJV).

​

Opposition and Persecution Begin

 

As the church grew, opposition intensified. The religious leaders arrested the apostles, but an angel released them from prison. When brought before the council again, Peter declared, "We ought to obey God rather than men. The God of our fathers raised up Jesus, whom ye slew and hanged on a tree. Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins" (Acts 5:29-31, KJV).

​

The first Christian martyr was Stephen, a man full of faith and the Holy Spirit. When falsely accused and brought before the council, Stephen gave a powerful speech reviewing Israel's history and showing how they had always rejected God's messengers. He told them, "Ye stiffnecked and uncircumcised in heart and ears, ye do always resist the Holy Ghost: as your fathers did, so do ye" (Acts 7:51, KJV). This enraged the religious leaders, and they stoned Stephen to death. As he died, Stephen saw heaven opened and Jesus standing at God's right hand. His last words echoed Jesus's words on the cross: "Lord, lay not this sin to their charge" (Acts 7:60, KJV).

 

The Gospel Spreads Beyond Jerusalem

 

Stephen's death sparked severe persecution, scattering believers throughout Judea and Samaria. But this persecution accomplished exactly what Jesus had predicted: the gospel began spreading beyond Jerusalem. Philip, another early believer, went to Samaria and preached Christ there. Many believed and were baptized, including a sorcerer named Simon.

​

An angel then directed Philip to a desert road where he met an Ethiopian official reading from the prophet Isaiah. The man was reading Isaiah 53:7-8, which describes the suffering servant: "He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth" (Acts 8:32, KJV). When the Ethiopian asked who the prophet was speaking about, "Philip opened his mouth, and began at the same scripture, and preached unto him Jesus" (Acts 8:35, KJV). This passage from Isaiah, written about 700 years before Jesus, clearly prophesied His suffering and death.

​

The Conversion of Saul

 

Meanwhile, a man named Saul was violently persecuting Christians, even having them killed. But on the road to Damascus, Jesus appeared to him in a blinding light and asked, "Saul, Saul, why persecutest thou me?" (Acts 9:4, KJV). This encounter transformed Saul completely. He became Paul, one of the greatest missionaries and teachers in Christian history. His dramatic conversion shows that no one is beyond God's reach.

​

The Gospel Goes to the Gentiles

 

A major turning point came when God gave Peter a vision showing him that the gospel was for all people, not just Jews. God told Peter, "What God hath cleansed, that call not thou common" (Acts 10:15, KJV). Peter then went to the house of Cornelius, a Roman centurion, and preached Jesus to him. While Peter was still speaking, the Holy Spirit fell on all the Gentiles who heard the message, and they began speaking in tongues just as the Jewish believers had at Pentecost. Peter realized that "God is no respecter of persons: But in every nation he that feareth him, and worketh righteousness, is accepted with him" (Acts 10:34-35, KJV).

This fulfilled the prophecies that God's salvation would reach all nations. Isaiah had written, "I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth" (Isaiah 49:6, KJV).

​

The Church at Antioch

 

In Antioch, believers were first called Christians. This diverse church became the launching point for missionary journeys to spread the gospel throughout the Roman Empire. Barnabas and Saul (now called Paul) were set apart by the Holy Spirit for this work.

 

Paul's Missionary Journeys

T

he second half of Acts focuses on Paul's three missionary journeys and his final journey to Rome as a prisoner. Paul traveled throughout Asia Minor and Greece, preaching in synagogues and public places, establishing churches, and writing letters to encourage believers. His message was consistent: Jesus is the Christ, the fulfillment of all Old Testament prophecies, who died for our sins and rose from the dead.

​

In Pisidian Antioch, Paul preached a powerful sermon connecting Jesus to Israel's history. He declared that God raised Jesus from the dead, fulfilling what was written in the Psalms: "Thou art my Son, this day have I begotten thee" (Acts 13:33, KJV, quoting Psalm 2:7). Paul explained that David's body remained in the tomb and saw corruption, but Jesus, whom God raised, did not see corruption, fulfilling Psalm 16:10.

​

Paul faced constant opposition, including beatings, imprisonment, and attempts on his life. In Philippi, he and Silas were beaten and imprisoned, yet they sang hymns at midnight. God sent an earthquake that opened all the prison doors, leading to the conversion of the jailer and his entire household. This demonstrates that even persecution serves God's purposes.

 

The Jerusalem Council

 

A crucial moment came when the church leaders met in Jerusalem to discuss whether Gentile believers needed to follow Jewish customs. After much debate, Peter reminded them of his experience with Cornelius and declared, "We believe that through the grace of the Lord Jesus Christ we shall be saved, even as they" (Acts 15:11, KJV). James, the brother of Jesus, concluded that Gentiles should not be burdened with Jewish law, referencing the prophet Amos who predicted that God would rebuild David's fallen tent so "that the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called" (Acts 15:17, KJV, quoting Amos 9:12).

​

This decision clarified that salvation comes through faith in Jesus Christ alone, not through keeping the law. It opened the door for the gospel to spread freely among all nations.

​

Paul's Journey to Rome

 

Paul's final journey to Rome came as a prisoner. Despite warnings, Paul felt compelled to go to Jerusalem, where he was arrested after being falsely accused. During his defense before various officials, Paul repeatedly shared his testimony and preached about Jesus. He told King Agrippa, "Having therefore obtained help of God, I continue unto this day, witnessing both to small and great, saying none other things than those which the prophets and Moses did say should come: That Christ should suffer, and that he should be the first that should rise from the dead, and should shew light unto the people, and to the Gentiles" (Acts 26:22-23, KJV).

Paul appealed to Caesar, his right as a Roman citizen, and was sent to Rome by ship. During the voyage, the ship was caught in a terrible storm and wrecked, but God protected everyone on board just as He had promised Paul. This showed that God's plan for Paul to testify in Rome would not be stopped by any circumstance.

​

The Ending of Acts

 

Acts ends with Paul in Rome under house arrest for two years, "preaching the kingdom of God, and teaching those things which concern the Lord Jesus Christ, with all confidence, no man forbidding him" (Acts 28:31, KJV). Though Paul was chained, the gospel was not. He welcomed all who came to him and continued proclaiming Jesus.

​

The book ends somewhat abruptly, which may be because Luke wrote it while Paul was still in Rome, or because the point of Acts is not to tell us everything that happened but to show how the gospel spread from Jerusalem to Rome, the center of the world at that time. The story continues through believers today.

​

Key Themes and Lessons

 

Acts shows us that Jesus Christ is the fulfillment of all God's promises in the Old Testament. The apostles consistently connected Jesus to the prophets, showing that His coming, death, and resurrection were all part of God's eternal plan. Jesus is the way of salvation for all people, both Jews and Gentiles. As Peter declared, "Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved" (Acts 4:12, KJV).

​

The Holy Spirit is the power behind everything that happens in Acts. Jesus promised that the Spirit would come, and when He did, everything changed. The Spirit gave the disciples boldness to preach, power to perform miracles, wisdom to make decisions, and courage to face persecution. Every believer receives the Holy Spirit when they believe in Jesus.

​

Acts teaches us that the church grows through the faithful testimony of believers, even in the face of opposition. Persecution scattered the believers, but wherever they went, they preached Jesus. The church multiplied not because of favorable circumstances but because believers were willing to suffer for the truth.

​

Prayer is central throughout Acts. The believers prayed before choosing leaders, before making major decisions, when facing opposition, and when seeking God's direction. Prayer was not just ritual but genuine communication with God that shaped everything they did.

​

Acts also shows God's heart for all nations. From Pentecost when people from many nations heard the gospel in their own languages, to Peter's vision about the Gentiles, to Paul's missionary journeys, we see God breaking down barriers and welcoming all who believe in Jesus. The promise God made to Abraham that all nations would be blessed through his seed was being fulfilled as people from every background came to faith in Jesus Christ.

​

Relevance for New Believers

 

For those who are new to following Jesus, Acts shows you that you are part of a story that began 2,000 years ago and continues today. The same Holy Spirit who empowered the first believers lives in you. The same Jesus who appeared to Paul can transform your life. The same message that turned the world upside down is still the power of God for salvation.

​

Acts demonstrates that following Jesus means being His witness wherever you are. You may face opposition or misunderstanding, but God will give you the words to speak and the courage to stand firm. The church is not a building but a community of believers who support one another, learn together, pray together, and serve together.

​

Most importantly, Acts shows that salvation is available to everyone who believes in Jesus Christ. It does not matter what your background is, what you have done, or where you come from. God's grace reaches all who call on the name of the Lord. As Paul and Silas told the Philippian jailer, "Believe on the Lord Jesus Christ, and thou shalt be saved" (Acts 16:31, KJV).

 

The Book of Acts is your story too. It shows how the church began and how it spread across the world. Now, as a follower of Jesus, you are part of that ongoing mission to share the good news that Jesus Christ died for our sins and rose from the dead, offering forgiveness and eternal life to all who believe in Him.
