Christ's priesthood is eternal because He was appointed by God and His sacrifice is once and for all, never needing renewal.
The eternal nature of Christ’s priesthood is rooted in His divine appointment and the finality of His sacrifice. Hebrews 7:23-25 explains that unlike the Levitical priests who faced death and could not continue in office, Christ, having risen from the dead, holds His priesthood permanently. His single sacrifice at Calvary was sufficient, ensuring that He can save to the uttermost all who draw near to God through Him. This guarantee of eternal salvation is signified by His ‘once for all’ offering, making His priesthood everlasting and unchanging.
