How do we know that the New Covenant is true?

The veracity of the New Covenant can be traced through prophetic declarations and their fulfillments within the scriptures. Jeremiah 31:31-34 lays the foundation for this covenant, which is ultimately fulfilled in the person of Jesus Christ, who serves as the mediator of this new relationship between God and His people. His sacrificial work on the cross confirms the promise that sins are forgiven, and indeed, the New Testament writings reflect this reality (Luke 22:20). Moreover, historical accounts and the consistent testimony of early Christians affirm that this covenant is not merely a theoretical construct but a living reality shaped by Christ's love and sacrifice. Through faith, believers experience the transformative power of this new promise, which is evidenced by a changed life and intimacy with God.
