Why is it important for Christians to understand the difference between the Old and New Covenants?

Recognizing the distinction between the Old and New Covenants is vital for Christians as it shapes their understanding of the Gospel and their daily walk of faith. The Old Covenant was never meant to provide salvation; rather, it served to highlight the need for a Savior by revealing the guilt of man. In contrast, the New Covenant offers the grace of God through Christ, who fulfills the law and provides true righteousness for believers. This knowledge frees Christians from the burden of law-keeping and enables them to live in a spirit of love and faith, validating their standing before God through Christ alone.
