How do we know Jesus is our priest forever?

The New Testament emphasizes that Jesus is our high priest forever in accordance with the divine order of Melchizedek. Hebrews 7:17 states, 'For it is witnessed of Him, “You are a priest forever after the order of Melchizedek.”' This indicates that unlike the Levitical priests who served temporarily, Christ's priesthood is eternal, having been established by God Himself. Furthermore, Jesus fulfills the priestly role by offering Himself as the ultimate sacrifice, thus both pacifying God's justice and providing a means of reconciliation for His people. As our great high priest, He intercedes for us, ensuring that we are always covered by His grace.
