How do we know the New Covenant is unconditional?

The distinction of the New Covenant lies in its unconditional nature, unlike the Sinai covenant which required obedience from the Israelites. As outlined in Hebrews 8:10, there are no stipulations that must be met for the covenant to be valid. This is consistent with God's dealings throughout redemptive history, where He sovereignly commits to His people, as seen with Abraham, where God's unilateral promise was carried out without the need for Abraham to fulfill conditions. The covenant is ultimately guaranteed by God’s mighty faithfulness and cannot fail, reassuring believers that their security does not depend on their performance but on the perfect work of Christ.
