How do we know the New Covenant is superior to the Old Covenant?
Answered in 2 sources
The New Covenant is superior because it is based on better promises and does not require works for salvation.
The superiority of the New Covenant over the Old is established in Hebrews, as it emphasizes grace over law. Unlike the Old Covenant, which required strict adherence to the law with penalties for disobedience, the New Covenant offers forgiveness and acceptance through the finished work of Christ. This is rooted in the promise of salvation that is solely by grace and provides assurances of eternal security, contrasting the impossibility of perfect obedience under the Old Covenant.
