How do we know Jesus is the fulfillment of the High Priest?

Jesus is the fulfillment of the High Priest as demonstrated through His life, death, and resurrection. In contrast to the Old Testament High Priests who offered animal sacrifices, Jesus offered Himself, the Lamb of God, which is mentioned in Hebrews 9:12. His once-for-all sacrifice satisfies the demands of justice and makes a way for believers to approach God directly. The symbolism in the High Priest's garments, which include the breastplate that bore the names of Israel, emphasizes Christ's intimate connection with His people, reminding us that He represents us before God constantly. Thus, His perfection qualifies Him as our eternal High Priest.
