Why is it important that Jesus is King and Priest?

The dual role of Jesus as both King and Priest is fundamental to Christian theology. As King, He governs with absolute authority, ruling over all creation as indicated in Psalm 110. This rule is characterized by justice and righteousness. Simultaneously, as our High Priest, He mediates between God and humanity, enabling us to approach God confidently. This combined role not only fulfills the Old Testament requirements for priesthood and kingship but also ensures that believers have a sovereign ruler who understands their plight and advocates for them before God, assuring their salvation and security.
