“For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. 17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.” (Romans 1:16-17)
“Paul said to the centurion and to the soldiers, Except these abide in the ship, ye cannot be saved.” (Acts 27:31)
“And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.” (Acts 2:40)
Here, we see those listening to Peter will be saved if they do something. But their salvation is not to heaven, it is FROM the evils of the society in which they lived. Peter uses the gospel to save children of God from the pitfalls of conforming to the world.
