Why is Christ's priestly work important for Christians?

The priestly work of Christ is essential for Christians because it establishes the means by which we are reconciled to God. According to Hebrews, Christ is the appointed high priest who fulfills all that the Old Testament priesthood foreshadowed. His sacrifice was not merely symbolic; it was effective in securing eternal redemption. As our mediator, He is the one who intercedes on our behalf, ensuring that we are seen as righteous before a holy God, highlighting the significance of His role in our ongoing relationship with Him.
