The new covenant is affirmed by the sacrificial death of Christ, which is the fulfillment of God's promise for redemption.
The new covenant is verified by the death and resurrection of Jesus Christ, serving as the testator whose blood validates the promises contained within the covenant. Hebrews 9:16-17 articulates that a will takes effect only upon the death of the one who made it, affirming Christ's death as the cornerstone of the new covenant. Furthermore, through His blood, we receive forgiveness, cleansing, and a permanent relationship with God. The effectiveness of this covenant is ensured because Christ lives to uphold it, as indicated in Hebrews 7:25, where He intercedes for those He has redeemed.
