What is the difference between the gospel and other messages in Christianity?

The gospel differs fundamentally from other messages in Christianity that may emphasize human effort or experience. It is a declaration of what Christ has accomplished through His death and resurrection, as articulated in Romans 1:16 where it is called the 'gospel of Christ.' Unlike messages that focus on moral living or personal experience, the gospel centers on God’s grace and the finished work of Christ, advocating that salvation is a gift and not a result of works. This distinction is crucial for understanding true salvation and avoiding self-righteousness; the gospel reassures believers that their hope rests solely on what Christ has done rather than their own efforts.
