Why is the concept of 'Christ alone' important for Christians?

'Christ alone' is a central tenet of Reformed theology that underscores the sufficiency of Jesus Christ in the plan of salvation. This concept is vividly illustrated in Galatians, where Paul confronts the Galatians about their inclination to revert to the law for salvation. By stating that there is no salvation or worship apart from the truth of the gospel, Paul emphasizes that any attempt to add works to salvation compromises the gospel's integrity. Being 'under the law' implies reliance on our efforts, a notion Paul vehemently opposes. He illustrates that the law's role is to expose sin, not to serve as a means to gain favor with God. Ultimately, 'Christ alone' ensures that our standing before God is based on His grace and not on our performance.
