The Book of Acts serves as the historical record of the early church, documenting exactly how the Apostles fulfilled the Great Commission. When we examine the “cases of conversion” throughout this book, a singular, consistent message emerges: salvation is found exclusively through the person and work of Jesus Christ, received by faith. It is vital to understand that this salvation is not based on our own works, religious efforts, or personal merit; it is a gift of God’s grace to those who trust in His Son.
In the original Greek, the word for “believe” (pisteuo) is used as a verb of action and trust. In the Book of Acts, the Apostles do not point seekers to their own goodness or the keeping of the Law as a means to reach heaven. They make it clear that human merit contributes nothing to our standing before God; instead, they point exclusively to the finished work of the Savior. Below are the definitive instances where the Apostles and early believers explained the way of salvation.
The Apostolic Witness: How to Be Saved
Acts 2:21
“And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.”
Context: On the Day of Pentecost, the Apostle Peter addresses a massive crowd of Jews in Jerusalem. He quotes the prophet Joel to explain the miraculous signs they are witnessing and to point them toward the only source of deliverance.(Note: Acts 2:21 isn’t adding a “verbal work” to salvation. It is describing the desperate, sincere reach of a soul toward the only Name that can save. If you believe He is the Savior, you will naturally “call” upon Him to be your Savior.)
Acts 4:12
“Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.”
Context: Peter and John have been arrested and are standing before the Sanhedrin, the Jewish high court. Boldly facing the very men who orchestrated the crucifixion, Peter declares the absolute exclusivity of Jesus Christ as the only Savior.
Acts 10:43
“To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.”
Context: Peter is at the house of Cornelius, a Roman Centurion. This marks a pivotal moment in history where the Gospel is officially presented to the Gentiles, confirming that forgiveness is available to “whosoever” believes, regardless of nationality.
Acts 13:38-39
“Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins: And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.”
Context: The Apostle Paul is preaching in the synagogue at Antioch in Pisidia. He explicitly tells the Jewish audience that the Law of Moses was insufficient to justify them, but that justification is now a reality for everyone who believes in Jesus.
Acts 15:11
“But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.”
Context: During the Jerusalem Council, the Apostles and elders meet to discuss whether Gentile believers must keep the Law of Moses. Peter stands up to settle the matter, affirming that both Jews and Gentiles are saved by the exact same means: the grace of Jesus Christ.
Acts 16:30-31
“And brought them out, and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.”
Context: Paul and Silas are in a Philippian prison when a violent earthquake strikes. The terrified jailer, realizing his spiritual need, asks the most important question in history, and the Apostles provide the most direct and simple answer: Believe.
Acts 26:18
“To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.”
Context: Paul is giving his defense before King Agrippa. He recounts his direct commission from the Lord Jesus on the road to Damascus, explaining that the mission of the Gospel is to bring people to forgiveness and an eternal inheritance through faith.
Conclusion
The testimony of Acts is clear: whether speaking to Jews at Pentecost or Gentiles in a Roman prison, the requirement remained the same. Salvation is by grace through faith in the Lord Jesus Christ. It is not a reward for the righteous, but a gift for the believer.
