Why is the concept of a high priest important for Christians?

The concept of a high priest is vital for Christians because it encapsulates the means by which believers can approach a holy God. In the Old Testament, the high priest performed the essential role of sacrificial atonement, mediating between God and the people. With the coming of Christ, He fulfills this role perfectly, as depicted in Hebrews 2:17, which notes that Christ had to be made like His brothers in every respect to be a merciful and faithful high priest. This understanding emphasizes the necessity of a mediator who can reconcile us to God. Without a high priest, we would stand condemned before God's holiness. Therefore, Christ's role as our high priest assures us that through His perfect sacrifice, we have bold access to God, as stated in Hebrews 4:16, where we are invited to approach the throne of grace with confidence.
