Why is the doctrine of covenant important for Christians?

Understanding the doctrine of covenant is vital for Christians as it reveals God's unchanging nature and His commitment to redeem His people. In Ezekiel 37, God states that He will make an everlasting covenant of peace with His people, emphasizing His unbreakable promise through Christ's blood. This covenant reassures believers of their identity and security within God's plans. It is a reminder that salvation is rooted in divine promise rather than human endeavor, underscoring the grace and mercy found in God's dealings with humanity from the Old Testament through the New Testament.
