What does the Bible say about Christ being the high priest?

Hebrews chapter 9 emphasizes Jesus Christ's role as the high priest who, unlike the mortal priests of the Old Covenant, entered the holy place in heaven itself, achieving eternal redemption through his own blood. The text illustrates that the sacrifices of the Old Testament were temporary shadows pointing to the reality found in Christ. By shedding his blood, Jesus has perfected for all time those who are being sanctified, ensuring that we can approach God without fear and with confidence.
