How do we know that Christ is our great high priest?

Christ's role as our great high priest is central to the theology of redemption found in the New Testament, especially in Hebrews. Hebrews 9:11-12 tells us that Christ entered the heavenly sanctuary with His own blood, obtaining eternal redemption for us. Unlike the Levitical priests who offered sacrifices daily, Christ offered Himself once for all, fulfilling the law and perfecting for all who are sanctified. This emphasizes that our cleansing and righteousness come not by our works but through His completed sacrifice, granting us access to God.
