What does the Bible say about the role of Jesus as a high priest?

According to the book of Hebrews, Jesus is described as the eternal high priest after the order of Melchizedek, which signifies his unique role in mediating between God and humanity. This mediation is essential because, as sinners, we are separated from a holy God, and it is through Jesus that we can gain access to His presence. Hebrews 7 emphasizes that Jesus is not just a typical priest but one who represents the ultimate sacrifice and intercedes on our behalf, ensuring that we have the hope of union with God.
