Why is it significant that Jesus is our high priest?

The role of Jesus as our high priest is central to the Christian faith because He fulfills the requirements of the old covenant and establishes a new and living way for us to access God. Hebrews 10:21 highlights that Jesus presides over the house of God, emphasizing His authority and ability to intercede for us. Unlike earthly priests who would offer continual sacrifices, Jesus' sacrifice was once and for all, perfecting forever those who are being sanctified. This assurance allows believers to rest in the fact that our sins are fully paid for and that we have a mediator who fully understands our struggles and needs.
