Hebrews 6:13–20 Hebrews has warned its hearers against the danger of spiritual sluggishness and apostasy, but the warning does not leave uncertainty as the foundation of perseverance. The author is persuaded of better things concerning them, things that accompany salvation, because he sees the continuing fruit of their faith in their service to the saints. His desire is that they continue with the same diligence to the end, becoming imitators of those who inherit the promises through faith and perseverance.
The next paragraph provides exactly such an example. Abraham received a promise from God and waited for its fulfillment. His perseverance did not rest upon his ability to make the promise come true, nor did the certainty of the promise depend upon Abraham’s circumstances remaining favorable. God had spoken, and God confirmed His promise with an oath. Hebrews uses Abraham to move from the exhortation to persevere into an explanation of why Christian hope can remain secure while fulfillment is still awaited.
Hebrews 6:13–20 (WEB) For when God made a promise to Abraham, since he could swear by no one greater, he swore by himself, saying, “Surely blessing I will bless you, and multiplying I will multiply you.” Thus, having patiently endured, he obtained the promise.
For men indeed swear by a greater one, and in every dispute of theirs the oath is final for confirmation. In this way God, being determined to show more abundantly to the heirs of the promise the immutability of his counsel, interposed with an oath; that by two immutable things, in which it is impossible for God to lie, we may have a strong encouragement, who have fled for refuge to take hold of the hope set before us. This hope we have as an anchor of the soul, a hope both sure and steadfast and entering into that which is within the veil; where as a forerunner Jesus entered for us, having become a high priest forever after the order of Melchizedek.
The Promise to Abraham The connection with the preceding paragraph is direct. Hebrews has just told its hearers to imitate those who
“through faith and perseverance inherited the promises.” Abraham now becomes the first example because his story combines all three elements: God gave a promise, Abraham trusted the God who promised, and fulfillment required patient endurance.
The quotation comes from Genesis 22, after Abraham obeyed God concerning Isaac.
Genesis 22:15–18 (WEB) Yahweh’s angel called to Abraham a second time out of the sky, and said, “I have sworn by myself, says Yahweh, because you have done this thing, and have not withheld your son, your only son, that I will bless you greatly, and I will multiply your offspring greatly like the stars of the heavens, and like the sand which is on the seashore.
Your offspring will possess the gate of his enemies. All the nations of the earth will be blessed by your offspring, because you have obeyed my voice.”
The promise itself had begun much earlier. God called Abraham from his country and promised to make from him a great nation, bless him, make his name great, and bring blessing to the families of the earth through him. The promise was subsequently repeated and developed, including the promise of offspring despite Abraham and Sarah’s advancing age.
Genesis 22 does not therefore introduce an entirely new promise. God confirms by oath what He has already promised and has begun to fulfill.
That broader history is important when Hebrews says that Abraham
“obtained the promise.” Hebrews itself can describe Abraham as one who received the promises while also saying that the patriarchs died without receiving them in their consummated form. Hebrews 11:17 calls Abraham the one who “had gladly received the promises,” while 11:13 says that the patriarchs died in faith “not having received the promises.” The language reflects different stages in the realization of what God had pledged.
Abraham genuinely received Isaac and saw decisive fulfillment of what God had spoken, while the larger promise concerning descendants, inheritance, and blessing to the nations continued beyond his lifetime. Abraham is therefore particularly appropriate for Christians being called to persevere. His life was shaped by a promise whose faithfulness he genuinely experienced while much of its fulfillment remained beyond what he could see. The hearers of Hebrews likewise live between what God has already accomplished and the final inheritance still set before them.
Having Patiently Endured Hebrews summarizes Abraham’s response with the words “having patiently endured.” The description does not require us to turn Abraham into an example of uninterrupted confidence. Genesis preserves his failures as readily as his faith. Abraham questioned how the promise would be fulfilled, and the attempt involving Hagar demonstrates that his journey was not free from serious misjudgment. Hebrews nevertheless looks at the course of Abraham’s life and identifies patient endurance as characteristic of his response to God’s promise.
Romans 4 describes Abraham’s faith from the standpoint of his settled confidence in God’s promise. Romans 4:20–21 (WEB) Yet, looking to the promise of God, he didn’t waver through unbelief, but grew strong through faith, giving glory to God, and being fully assured that what he had promised, he was also able to perform.
Genesis does not hide the weakness and misjudgments that occurred along the way, but Paul identifies the defining trajectory of Abraham’s faith: his confidence rested upon God’s ability to accomplish what He had promised. That provides an important contrast with the wilderness generation that has occupied so much of Hebrews’ argument. Israel en- countered circumstances that appeared incompatible with God’s promise and responded by concluding that He could not be trusted to accomplish what He had said. Abraham also encountered circumstances that made fulfillment appear impossible, yet his story became an example of faith and patient endurance because he continued to trust the God who had spoken.
Patient endurance in Hebrews is therefore not passive waiting. It is continued trust in the reliability of the One who has spoken while the complete fulfillment of His promise remains unseen.
He Swore by Himself Hebrews directs attention not only to the promise but to the unusual manner in which God confirmed it:
“Since he could swear by no one greater, he swore by himself.” An oath ordinarily appeals to someone greater than the person making it.
The person swearing places the truthfulness of his statement beneath the authority of the one by whom he swears. Hebrews explains this ordinary human practice in verse 16: people swear “by a greater one,” and the oath functions as confirmation intended to bring a dispute to an end.
God cannot appeal to a greater authority because no greater authority exists, so He swears by Himself. The point is not that His ordinary word would otherwise be unreliable. Hebrews will explicitly say that it is impossible for God to lie, which means the promise was already certain because God had spoken it. The oath provides additional confirmation for the benefit of those receiving the promise rather than supplying reliability that God’s word previously lacked. Genesis itself emphasizes the extraordinary character of the declaration: “I have sworn by myself, says Yahweh.” God places the confirmation of the promise upon His own character, so its ultimate certainty rests not upon favorable circumstances or human ability but upon the identity and faithfulness of the God who made it.
The Heirs of the Promise Hebrews extends the significance of the oath beyond Abraham:
“God, being determined to show more abundantly to the heirs of the promise the immutability of his counsel, interposed with an oath.”
The oath was spoken to Abraham, but Hebrews addresses people who are themselves described as “the heirs of the promise.” The promise has therefore not remained confined to the patriarch as an isolated historical event. Those who inherit what God promised stand within the continuing purpose confirmed by that oath.
Hebrews will later develop the identity of these heirs through its discussion of faith, promise, inheritance, and the people of God. Here the emphasis falls upon the character of God’s purpose toward them. His counsel is described as immutable, placing the stability of the promise in God rather than in the circumstances surrounding its heirs. God is not moving uncertainly through history or making promises whose fulfillment depends upon developments He failed to anticipate.
Nor does the oath represent God attempting to convince Himself to remain committed to something He might otherwise abandon. It is given for the heirs. God provides confirmation in a form familiar to human beings so that they may recognize the certainty of what He has determined. The emphasis therefore falls not upon the strength of those who inherit the promise but upon the stability of the One whose promise they inherit.
Two Immutable Things Hebrews says that believers possess strong encouragement through “two immutable things.” The natural referents are God’s promise and His oath, both of which are unchangeable because both rest upon His character.
The oath does not transform an uncertain promise into a certain one but gives a second confirmation of something that was already certain because God had spoken it.
Hebrews states the theological foundation beneath both when it says that “it is impossible for God to lie.” The certainty of the promise therefore rests upon the truthfulness of God Himself. That statement is particularly significant after the severe warning immediately preceding it. Hebrews has not moved from warning to reassurance by minimizing the seriousness of apostasy, nor does it ground assurance in the hearers’ ability to predict their own future performance. It directs them toward the God whose promise and oath cannot fail. The warnings call the hearers to continue trusting Him, while the promise and oath establish why such trust is warranted. Perseverance does not require confidence in human constancy when its object is the God whose character does not change.
Fled for Refuge Hebrews describes its hearers as those “who have fled for refuge to take hold of the hope set before us.” The language naturally recalls the Old Testament provision of cities of refuge, where someone who had unintentionally killed another person could flee from the avenger of blood and receive protection while the case was judged. Hebrews does not explicitly identify the phrase as a reference to those cities, however, so the possible connection should not carry more weight than the text gives it. The broader image of fleeing toward safety is sufficient for the argument. The expression combines urgency and dependence. Someone fleeing for refuge does not regard the refuge as an optional improvement to an already secure position but moves toward it because safety is found there.
In the same way, the hearers have fled toward the hope God has placed before them rather than creating security for themselves.
This language fits the exhortations Hebrews has repeatedly given. The hearers are to hold tightly to their confession, approach the throne of grace, press on toward maturity, and continue in faith. Their security is not found by turning inward and attempting to measure the strength of their own confidence but by taking hold of the hope provided by the God whose promise and oath have just been described. An Anchor of the Soul Hebrews now gives one of its most memorable images:
“This hope we have as an anchor of the soul, a hope both sure and steadfast…”
An anchor provides stability by securing a vessel to something outside the vessel itself. Its usefulness does not depend upon preventing wind, waves, or movement. A ship may still experience conditions beyond its control, but the anchor provides stability against being carried away by them.
The image is particularly appropriate in a letter that began by warning its hearers against drifting and has repeatedly addressed circumstances requiring endurance.
The anchor cannot be separated from the promise and oath immediately preceding it. Christian hope is not sure and steadfast merely because hope provides psychological comfort or because optimism makes suffering easier to endure. Its security rests upon the God who cannot lie. The hope set before believers reaches beyond their changing circumstances and their own imperfect constancy to the unchanging purpose of the God who has spoken.
Hebrews then joins the anchor image to the sanctuary imagery that has been developing throughout the letter. The hope is described as
“entering into that which is within the veil.” The controlling idea is no longer merely stability amid danger but access to the presence of God, where Jesus has already entered. Within the Veil Under the Mosaic covenant, the veil separated the Most Holy Place from the rest of the sanctuary. Behind it stood the ark and the mercy seat, associated with the presence of God. The high priest alone entered that space, and he did so only according to the conditions God established for the Day of Atonement.
Hebrews has already used that background when describing Jesus as the great High Priest who “has passed through the heavens.” The earthly high priest passed through the veil into the earthly Most Holy Place; Jesus has entered the heavenly reality into the presence of God Himself. Christian hope therefore reaches into the place ordinary Israelites could not enter. Its stability rests not only upon God having made a reliable promise concerning the future but upon the fact that Jesus has already entered the divine presence toward which that hope reaches. The sanctuary imagery and the language of the anchor converge in the priestly work of Christ.
Jesus Entered for Us Hebrews says that Jesus entered “for us,” preserving the representative character of His priesthood. His entrance into God’s presence is not simply a personal return to heavenly glory after completing His earthly ministry. He enters on behalf of the people He represents.
The argument that began with Jesus sharing flesh and blood now reaches into the heavenly sanctuary. The Son became like His brothers so that He could become their merciful and faithful High Priest. He experienced human weakness, endured testing without sin, learned obedience through suffering, passed through death, and has now entered the presence of God on behalf of those He represents.
The believer’s hope therefore reaches where the believer has not yet gone because the believer’s representative is already there. The security communicated by the anchor image is more than confidence in a future destination. It is confidence grounded in the presence of Christ at that destination and in His continuing priestly representation of His people before God.
The Forerunner Hebrews develops the significance of Jesus’ entrance further by calling Him a “forerunner”:
“…where as a forerunner Jesus entered for us…” A forerunner is someone who goes ahead in anticipation of others following. The description therefore adds something to the ordinary imagery of the high priest entering the Most Holy Place. Aaron entered behind the veil as Israel’s representative, but he did not enter as the first member of a procession that would eventually bring the congregation into the sanctuary. The restriction remained, and ordinary Israelites did not subsequently follow him behind the veil.
Jesus enters as both representative and forerunner. His entrance into God’s presence on behalf of His people also anticipates their arrival where He has gone. This fits the larger trajectory Hebrews has already established. The Son brings “many sons to glory,” calls them brothers, shares their humanity, and passes through suffering and death. His entrance into God’s presence as their forerunner now identifies the destination toward which the people He represents are moving. The term therefore contributes something important to Christian hope.
Jesus has not merely secured benefits in a heavenly location permanently inaccessible to those He represents. His own entrance anticipates theirs.
The hope entering within the veil reaches toward a destination already occupied by the One who went there ahead of them.
A Priest Forever The paragraph ends where the interrupted argument began:
“…having become a high priest forever after the order of Melchizedek.” Hebrews has brought its hearers back to Psalm 110. The author introduced
Melchizedek in 5:6 and again in 5:10, then interrupted the explanation because his hearers had become dull of hearing. He rebuked their immaturity, warned them about the danger of falling away, encouraged them concerning the fruit already visible in their lives, and called them to imitate those who inherit the promises through faith and perseverance.
Abraham provides the bridge back to the priestly argument. He received God’s promise and patiently endured, while God confirmed His purpose with an oath. That oath demonstrates the unchangeable character of God’s purpose toward the heirs of the promise, giving them strong encouragement to take hold of the hope set before them. Their hope reaches behind the veil because Jesus has already entered there on their behalf as their forerunner, and the Jesus who entered is the High Priest appointed forever according to the order of Melchizedek.
The apparent interruption has therefore prepared the hearers to return to the subject with a fuller understanding of why it matters. Christ’s Melchizedekian priesthood is not an isolated piece of theological information. It belongs directly to the security of the hope Hebrews has called its hearers to hold.
Promise, Oath, and Hope Hebrews 6:13–20 grounds Christian perseverance in realities that do not originate in the believer. Abraham illustrates what life between promise and fulfillment looks like. God spoke, Abraham waited, and the waiting included weakness, misjudgment, uncertainty, and circumstances that appeared incompatible with what God had promised. Yet the certainty of the promise did not depend upon Abraham possessing flawless confidence at every moment. It rested upon the God who had spoken.
God confirmed that promise with an oath, not because His word required additional reliability but because He desired to demonstrate more abundantly the unchangeable character of His purpose to the heirs of the promise. Promise and oath therefore converge upon the same foundation: the truthfulness of the God for whom lying is impossible.
The hearers of Hebrews can possess strong encouragement because the hope set before them rests ultimately upon His character rather than their ability to control the circumstances through which they must persevere.
Yet Christian hope has an additional ground for confidence that Abraham’s example prepares Hebrews to explain: Jesus has already entered the heavenly presence toward which His people are moving. The great High Priest who shared their humanity, endured suffering, passed through death, and was appointed by God has entered within the veil on their behalf. His designation as forerunner means that His entrance anticipates theirs. He has gone ahead of the people He represents, so their hope reaches toward a destination already occupied by their High Priest.
The warning against apostasy in the preceding section and the assurance of this passage consequently belong together. Hebrews does not answer the danger of falling away by directing Christians toward confidence in themselves. It directs them toward the faithfulness of God and the priestly work of Christ while continuing to call them to faith and patient endurance. Abraham is an appropriate example not because his life displays uninterrupted strength but because his faith endured toward fulfillment promised by a faithful God.
The discussion has now returned to the point at which Hebrews paused in 5:10. Jesus has been named by God a High Priest forever according to the order of Melchizedek. The hearers have been warned against the sluggishness that prevented them from following that argument, called toward maturity, confronted with the danger of apostasy, and directed toward the promise and oath that ground their hope. Hebrews is now ready to explain the priesthood it has twice announced and deliberately postponed.
