How do we know that the New Covenant is based on grace?

We can be assured that the New Covenant is centered around grace through the promises and declarations made in Scripture. Hebrews emphasizes that Christ has fulfilled the requirements of the law, and through His sacrifice, we are granted access to God without further obligations. The covenant emphasizes 'done' instead of 'do'; it is not about what we accomplish but about what Christ has already completed. Believers are united with Christ's righteousness, meaning they are seen as righteous in God's eyes because of the finished work of Christ on the cross. This understanding transforms our approach to salvation, affirming that it is a gift of grace, not based on our works or merits.
