What does the Bible say about Christ as the Lamb and High Priest?

In John 18, we see a vivid portrayal of Christ as the Lamb of God who willingly submitted to the arrest and the pressure of the high priest's court, illustrating His dual role as both the sacrificed Lamb and our High Priest. The Old Testament sacrificial systems pointed to Christ, who is the ultimate freewill offering, bound for our sins and curse, thereby providing atonement for His people. As our High Priest, Christ enters the holiest of holies with His own blood, securing eternal redemption and representing us before God. This duality emphasizes the sufficiency of Christ's work in saving sinners.
