What does the Bible say about the gospel of substitution?

The gospel of substitution is a core truth presented by Jesus, which asserts that He was delivered into the hands of men, crucified, and resurrected on the third day. This truth serves as the foundation by which God justifies all His elect. Scripture consistently affirms this teaching—Christ bore our sins in His own body (1 Peter 2:24) and was raised again for our justification (Romans 4:25). This gospel emphasizes that salvation is found in a person, Jesus Christ, and shows that His sacrifice was not for Himself, but for the sins of His people.
