How do we know Christ fulfills the Old Covenant?

The New Testament, particularly the book of Hebrews, outlines how Christ accomplished what the Old Covenant could not. While the Old Covenant revealed God's standards for holiness, it became clear that no one could fulfill its demands perfectly. Christ, however, lived a sinless life and obeyed the law fully on our behalf. In His death, he bore the weight of sin, thus fulfilling the sacrificial system that the temple represented. This transition from the Old to New Covenant is significant because it showcases God's plan of redemption, where the shadow of the law gives way to the reality found in Christ. Therefore, understanding Christ as the fulfillment of the Old Covenant helps believers appreciate the depth of God's mercy and grace in providing a way to true righteousness through faith in Him.
