Why is the concept of Christ as both priest and king important for Christians?

The dual role of Christ as both priest and king is crucial in understanding the fullness of His work on behalf of believers. As a king, He rules with divine authority, and as a priest, He mediates on behalf of His people, ensuring that they are reconciled to God. This is rooted in Hebrews, where it states that Jesus is a priest forever after the order of Melchizedek, highlighting His eternal priesthood and ability to save completely. The peace and counsel between His priestly and kingly offices reflect the complete nature of salvation, necessitating that believers not only receive atonement for sins but also willingly submit to Christ's lordship in their lives.
