Why is it important that Jesus is a priest forever?

The eternal priesthood of Jesus is vital for several reasons: it assures us of His constant intercession on our behalf, representing us before the Father. As Hebrews explains, He 'ever liveth to make intercession' for those who come to God through Him. This unchanging nature of His priesthood contrasts with the temporary and fluctuating roles of human priests, thereby providing believers with a steadfast assurance that our salvation is secure. Additionally, His everlasting priesthood points to the fulfillment of God's covenantal promises, affirming that believers are eternally included in the family of God.
