How do we know the everlasting covenant is true?

The truth of the everlasting covenant is rooted in the character of God Himself, who is faithful and cannot lie. This covenant, as attested in Scripture, embodies God's promise to His elect and is ensured through Christ's work on our behalf. As stated in Hebrews 13:20, God brought Jesus back from the dead through the blood of the everlasting covenant, thus affirming its validity and permanence. Our confidence in this covenant is founded on faith, which God graciously provides, allowing us to rest in the assurance that all that God has promised will be fulfilled.
