Why is understanding the old and new covenants important for Christians?

The distinction between the old and new covenants is crucial for understanding the heart of the gospel. Hebrews 9:8-10 explains that the old covenant served as a figure, pointing to the ultimate reality found in Christ. It was intended to reveal the inability of the law to save, preparing the way for the new covenant, which is grounded in grace and fulfilled in Christ's work. By recognizing that the old covenant was set up with the blood of animals and required continual sacrifices, believers can appreciate the finality and sufficiency of Christ's sacrifice, which resolved the issue of sin once and for all. This foundational understanding not only enhances our assurance of salvation but also propels Christians to live in gratitude and obedience, reflecting the transformative impact of grace in our lives.
