How do we know that Christ is the fulfillment of the sacrifices?

The Bible indicates that the Old Testament sacrifices were performed repeatedly and could never effectively take away sins (Hebrews 10:11). In contrast, Christ, through His one offering, perfected forever those who are sanctified (Hebrews 10:14). This singular act of atonement established Him as the ultimate fulfillment of every sacrificial requirement laid out in the Old Testament, demonstrating that He is not only the priest but also the sacrifice. This reality affirms that His sacrifice was sufficient, removing the need for further offerings.
