What does the Bible say about the gospel that saves?

The gospel that saves is presented in 1 Corinthians 15:1-4, where Paul declares it consists of Christ dying for our sins, being buried, and rising again on the third day. This fundamental message stresses that salvation comes through the preaching of this gospel, as it is the means by which God saves chosen sinners, confirming their faith in Christ.
