“And inasmuch as not without an oath he was made priest: (For those priests were made without an oath; but this with an oath by him that said unto him, ‘The Lord swore and will not repent, Thou art a priest for ever after the order of Melchizedek’).”
(Hebrews 7:20-21)
The concept of priesthood in Scripture finds its consummation in Jesus Christ, who was ordained to His office with a divine oath. This act marked Him as distinct from all others. His priesthood was sworn into existence by God Himself, who declared that Christ would be the eternal High Priest, never to be replaced, never to be set aside—an unshakable confirmation of a covenant rooted in God’s unchangeable Word.
Hebrews 7:20-22 outlines this shift. The Levitical priests of the old covenant were made priests without any oath. They were chosen, served for a time, and then passed away. But Christ’s appointment was sealed with the Lord’s own words: “Thou art a priest for ever after the order of Melchizedek.” This statement confirms that Christ’s role as advocate and intercessor for His people would never fail, never be interrupted, and never require succession.
The Levitical priests operated under a covenant that required constant repetition—sacrifices day after day, year after year. Those rituals, though commanded, were themselves shadows, pointing forward to a better priest and a better sacrifice. Christ’s priesthood is the substance that fulfills the shadow. By His once-for-all offering on the cross, He brought to completion what the blood of bulls and goats could never accomplish. In His death, the need for continual sacrifices ended, for He satisfied every demand of divine justice and secured redemption for His people.
Hebrews 7:22 declares that Jesus is the surety of a better covenant, that is to say, one who guarantees fulfillment. The Levitical priesthood could never guarantee anything beyond temporary atonement. But Christ, being both priest and sacrifice, both mediator and guarantor, secures every promise of God’s covenant. His priesthood ensures that the blessings of this covenant cannot be revoked, for they rest on His completed work and God’s sworn oath.
This truth completely changes how believers gain access to God. The old covenant required priests to stand between God and the people, continually mediating through ritual. Under Christ’s priesthood, however, the door to God is permanently open. His intercession does not falter, His priesthood does not lapse, and His mediation does not weaken. Believers can now approach God not in fear of rejection but with confidence that Christ’s blood has secured their welcome.[1]
The implications of this distinction are immense. No longer is salvation tied to the frailty of men or the repetition of rituals. It is secured in the eternal priesthood of Christ and upheld by the unchanging oath of God. His priesthood is not only superior but unshakable and eternal. And through Him we have direct access to God, guaranteed by divine promise and sealed by His sacrifice.
Contemplations:
- A priest like no other. I’m amazed at the distinctive nature of Christ’s priesthood. Unlike the temporary and repetitive duties of Levitical priests, Jesus’ priesthood is eternal and founded on an unchangeable oath by God Himself. This assurance fills me with peace, knowing that my intercessor never changes nor defaults and that His covenant with me is secure.
- The surety of salvation. Reflecting on Jesus as the surety of a better testament brings immense comfort. His role as surety means that all the promises God has made are yes and amen in Him. This truth secures my faith and strengthens my trust in the reliability of God’s Word.
- The unchanging promise. When I think about the oath God made regarding Christ’s priesthood, “The Lord swore and will not repent” (Hebrews 7:21), it reminds me of the unchanging nature of God and that His promises are as steadfast as His character.
- Eternal access through Christ. The consequence of Christ’s eternal priesthood is personal and transformative. Because He intercedes for me, I have continual access to God’s throne of grace. This privilege of direct access allows me to approach God boldly and with confidence, because I know I am welcomed and loved.
Prayer (adoration):
O Lord most high, I lift my heart in worship to You for the oath You swore concerning Your Son. You declared Him to be a priest forever after the order of Melchizedek, and You do not repent of Your Word. I adore You for this eternal priesthood that rests not on the frailty of men but on Your unchanging will. In Christ I see the beauty of Your faithfulness in this covenant that cannot be broken, sealed by Your own name.
I praise You for the majesty of Jesus, my great High Priest. His priesthood is unlike the old, for He ministers not with the blood of beasts but with His own precious blood. His sacrifice was not a shadow but the substance, not temporary but final, not symbolic but saving. In Him mercy and truth meet together, righteousness and peace embrace.
I adore You for Christ’s role as surety of the better covenant. He is the guarantor that every promise You have spoken is yes and amen in Him. No fear of failure shadows my salvation, for it rests in the hands of the Son who cannot fail. I worship You for giving me such a secure foundation, a covenant rooted in Your unchanging oath and accomplished by Christ’s eternal priesthood.
I praise You for His continual intercession. Even now, at Your right hand, He pleads for me. His wounds speak louder than my sins, His blood declares pardon where guilt would cry for judgment. O Lord, what greater reason could I have to worship than this—Christ lives to intercede for me!
I adore You for granting me direct and lasting access to Your throne. No veil stands between us, no human priest is needed to mediate my approach. Christ Himself has opened the way, and through Him I come boldly, confidently, joyfully. This privilege is not mine by right but by grace, secured by Your Son’s eternal office.
O God, You are unchanging, Your Word unshakable, Your covenant unbreakable. I worship You for Your steadfast love, for Your oath that cannot fail, and for Your priest who reigns forever. Let my life echo back Your praise, let me speak often of Your greatness, and let my heart be filled with adoration for the eternal priesthood of Christ, Your Son, my Savior.
In Jesus’ name I pray, Amen.
