What is the content of the gospel according to the Bible?

The biblical gospel focuses on the person of Jesus Christ and the redemptive work He accomplished through His life, death, and resurrection. Paul clarifies in Romans 16:25 that the gospel is 'according to the preaching of Jesus Christ,' which underscores that the gospel isn’t merely ethical teachings but is grounded in the historic and theological reality of Christ's identity. The gospel declares that through Jesus, individuals find forgiveness of sins and righteousness because He was appointed by God as the mediator and redeemer. This doctrine is critical for believers as it articulates the source of salvation and the means through which God reconciles sinners to Himself.
