Why is Christ's role as our High Priest significant?

The significance of Christ as our High Priest is foundational to Reformed theology. As stated in Hebrews 10, He is described as having a vital role over the house of God, making intercession for sinners. This means that despite our continual struggle with sin, believers can approach God with full assurance, cleansed by the blood of Christ. Our reliance on Him ensures that we are seen as faultless before God, as He fulfills the requirements of the law on our behalf. His perfect sacrifice provides the only basis for our hope and confidence in salvation.
