Why is understanding Jesus as the covenant essential for Christians?

For Christians, recognizing Jesus as the covenant affirms that their salvation is rooted in a person, not just a set of rules or agreements. This covenant represents an eternal promise from God, ensuring that He will not break His commitment to His people. The covenant's stability lies in Christ’s obedience and sacrifice, as He fulfills all that is necessary for redemption. This understanding provides believers with assurance of their eternal security and relationship with God, as they are included in this divine covenant through faith in Christ.
