No, God did not change how salvation works. People have always been saved by grace through faith, never by perfectly keeping the law. In Acts 10:1-48, God gives Peter a vision of unclean animals and sends him to the home of Cornelius, a Roman officer. Peter learns that God shows no favoritism, and the Holy Spirit falls on Gentiles who believe. The story makes clear that salvation is not about being ritually clean. It is about trusting God’s promised Savior, Jesus.
Setting the Scene in Acts 10:1-48
This chapter completes a short series within Acts about how salvation works. We’ve seen that no one is too far gone for God (Acts 8:26-40), how conversion works in Saul’s story (Acts 9:1-19), and how we can know if we’re really saved (Acts 9:20-31). Between these stories, Luke follows Peter as he travels to Lydda and Joppa, healing a paralyzed man named Aeneas and raising a woman named Tabitha (Acts 9:32-43).
To feel the weight of this chapter, it helps to know that Jewish tradition counts 613 commandments in the Law of Moses, many of them dealing with purity. Food laws separated clean animals from unclean ones (Leviticus 11). Sharing a meal was a sign of fellowship, so eating with Gentiles, who didn’t keep those laws, was something observant Jews avoided. Many assumed that staying clean was how a person stayed right with God. Acts 10 changes that assumption.
A Gentile Who Feared God
The story begins in Caesarea, the grand port city Herod the Great built on the Mediterranean coast. It served as the Roman headquarters for Judea.
Acts 10:1-4 At Caesarea there was a man named Cornelius, a centurion in what was known as the Italian Regiment. He and all his family were devout and God-fearing; he gave generously to those in need and prayed to God regularly. One day at about three in the afternoon he had a vision. He distinctly saw an angel of God, who came to him and said, “Cornelius!” Cornelius stared at him in fear. “What is it, Lord?” he asked. The angel answered, “Your prayers and gifts to the poor have come up as a memorial offering before God.”
A centurion commanded about a hundred soldiers. Cornelius was one of the “God-fearers,” Gentiles who worshiped Israel’s God, prayed, and gave generously without becoming full Jewish converts. Three in the afternoon was a traditional Jewish hour of prayer, connected with the evening sacrifice at the temple. The angel told Cornelius to send for Simon Peter, who was staying with a tanner in Joppa, a seaport about 30 miles south.
Notice that Cornelius was sincere and generous, yet he still needed to hear the gospel. Good deeds didn’t save him. God was drawing him toward the message of Jesus.
Peter’s Rooftop Vision
Peter’s location is worth noticing. Tanners worked with the hides of dead animals, and many Jews considered the trade unclean. Peter was already stretching his comfort zone. Joppa was also the port where Jonah once boarded a ship to run away from God’s call to preach to Gentiles (Jonah 1:3). Now, in the same town, God was about to send another reluctant Jewish messenger to Gentiles.
Acts 10:11-15 He saw heaven opened and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals, as well as reptiles and birds. Then a voice told him, “Get up, Peter. Kill and eat.” “Surely not, Lord!” Peter replied. “I have never eaten anything impure or unclean.” The voice spoke to him a second time, “Do not call anything impure that God has made clean.”
Peter’s reply, “Surely not, Lord!” is almost a contradiction. You can’t call someone Lord and tell him no in the same breath. Even after following Jesus for years, Peter hadn’t fully grasped what Jesus taught when he declared all foods clean (Mark 7:19). The vision came three times, perhaps a gentle echo of the three times Peter denied Jesus and the three times Jesus restored him.
The Pillar New Testament Commentary explains that the clean and unclean laws were temporary. They were designed to keep Israel holy and distinct until the time when Jews and Gentiles could be forgiven and made holy on the same basis, through faith in Christ.
It Was About People
While Peter was still puzzling over the vision, Cornelius’s men arrived. The next day Peter went with them, and when he entered the centurion’s house, he explained what he had learned.
Acts 10:27-29 While talking with him, Peter went inside and found a large gathering of people. He said to them: “You are well aware that it is against our law for a Jew to associate with or visit a Gentile. But God has shown me that I should not call anyone impure or unclean. So when I was sent for, I came without raising any objection. May I ask why you sent for me?”
The vision wasn’t really about food. It was about people. God could have explained the gospel to Cornelius through the angel. Instead, he sent Peter, and that wasn’t only for Cornelius’s sake. It was for Peter’s sake and the whole church’s. The same pattern happened in Samaria, when God waited for Peter and John before giving the Spirit (Acts 8:14-17). God wanted the apostles to see with their own eyes that the door was open.
God Shows No Favoritism
Peter began his message with a discovery that turned his world upside down.
Acts 10:34-36 Then Peter began to speak: “I now realize how true it is that God does not show favoritism but accepts from every nation the one who fears him and does what is right. You know the message God sent to the people of Israel, announcing the good news of peace through Jesus Christ, who is Lord of all.”
The Greek idea behind “favoritism” is literally receiving someone’s face, judging by outward appearance or ethnicity. God doesn’t do that. Jesus is Lord of all, not just Lord of Israel. Peter went on to summarize the gospel: Jesus’ ministry, his death on a cross, his resurrection, and his coming role as judge. Then he made the key point.
Acts 10:43-46 All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name. While Peter was still speaking these words, the Holy Spirit came on all who heard the message. The circumcised believers who had come with Peter were astonished that the gift of the Holy Spirit had been poured out even on Gentiles. For they heard them speaking in tongues and praising God. Then Peter said…
This is sometimes called the Gentile Pentecost. Just as at Pentecost (Acts 2:1-13), the Spirit came and the believers spoke in tongues. This time it happened before baptism and without the laying on of hands, which shows that the Spirit is God’s gift, given in response to faith. Christians differ on how tongues function today; for more, see Is Speaking in Tongues Biblical? Peter then had the new believers baptized, welcoming them publicly into the church. The fallout from this moment will carry into the next lesson (Acts 11:1-30).
Saved by Faith All Along
So did salvation work one way in the Old Testament and another in the New? Peter said all the prophets testified that everyone who believes in Jesus receives forgiveness. That means the answer is no. Everyone who has ever been saved has been saved by faith. Paul made the same argument using Abraham.
Romans 4:1-3 What then shall we say that Abraham, our forefather according to the flesh, discovered in this matter? If, in fact, Abraham was justified by works, he had something to boast about—but not before God. What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.”
Abraham trusted God’s promise of offspring when it was humanly impossible, and God counted his faith as righteousness (Genesis 15:6). Paul also quoted the prophet Habakkuk: the righteous will live by faith (Galatians 3:11). No one was ever saved by perfectly keeping the law. The law showed people their need and pointed forward to the One who would keep it perfectly. In the Old Testament, believers trusted God’s promised Messiah without knowing his name. In the New Testament, that promise has a name: Jesus. As Peter told the Sanhedrin, salvation is found in no one else (Acts 4:12).
What This Means for Us
Many people still try to earn God’s favor by staying “clean,” keeping rules, attending church, or avoiding the worst sins. Rules aren’t bad, but they can’t save. If you’ve ever felt unclean, Acts 10 has good news: God makes people clean through faith in Jesus. What he has made clean, no one can call unclean.
This passage also challenges our prejudices. Peter had to unlearn a lifetime of thinking certain people were off-limits. God shows no favoritism, so we can’t either. The gospel is for every nation, every background, and every person.
The Takeaway
Did God change how salvation works? No. Salvation has always come by grace through faith in God’s promised Savior. In Acts 10, Peter learned that God shows no favoritism, and Gentiles received the Spirit simply by believing in Jesus. Abraham was saved by faith, Cornelius was saved by faith, and we are saved the same way.
