What is the everlasting covenant and its significance in the gospel?

The everlasting covenant is foundational to understanding God's initiative in salvation. It reflects His eternal purpose to redeem a people for Himself through Christ. Hebrews 13:20 points to the 'blood of the everlasting covenant,' signifying that this covenant is ratified by Christ's sacrificial death. The significance lies in the assurance it provides believers, confirming that God's promises are immutable. Since this covenant does not depend on human actions but is entirely God's work, it grants peace and security to those who believe.
