Understanding Hebrews 6:18-20 in Depth: Hope Anchored in Heaven

Why This Hope Is So Urgent

These verses don’t come out of nowhere - they’re meant to steady believers who were starting to drift away from their faith.

The original readers of Hebrews were spiritually sluggish and in danger of giving up under pressure, as the author warns in Hebrews 5:11‑6:12. He’s afraid they might stop growing and even turn back, which is why he urges them to 'hold fast' to hope. The phrase 'we who have fled for refuge' shows they’re running to God for safety, like someone escaping to a sanctuary in a time of danger.

This hope is a lifeline because Jesus has already entered the inner sanctuary of heaven for us, as Psalm 110:4 promises: 'You are a priest forever, after the order of Melchizedek.'

The Unshakable Foundation of Our Hope

The 'two unchangeable things' the writer refers to are God’s promise and His oath - first seen when He promised Abraham, 'I will surely bless you,' and then confirmed it with an oath, saying, 'By myself I have sworn,' as recorded in Genesis 22:16-17.

These two - promise and oath - were the strongest form of assurance in the ancient world, like a legal guarantee backed by a solemn vow. Since God cannot lie, these are not just comforting words but rock-solid realities. The writer uses them to show that our hope is not based on wishful thinking, but on God’s own character. This is why believers can 'flee for refuge' with confidence, like someone reaching a city of safety, knowing the door will not be shut.

The image of hope as an 'anchor of the soul' draws from the tabernacle, where the curtain guarded the Holy of Holies - God’s presence, above the ark, as described in Exodus 26:34. But now, Hebrews says, our hope 'enters into the inner place behind the curtain,' not through animal sacrifices, but through Jesus Himself. He entered not a man-made sanctuary, but heaven itself, as Hebrews 9:11-12, 24 explains: 'He entered once for all, not by the blood of goats and calves but by his own blood, thus securing eternal redemption.'

Because God cannot lie, His promise and His oath are two unbreakable pillars holding up our hope.

And He went there as our forerunner, like a pioneer who blazes a trail so others can follow. This fulfills Psalm 110:4: 'You are a priest forever, after the order of Melchizedek' - a priesthood not based on ancestry like the Levites, but on eternal life and divine appointment. Unlike the old priests who died and could not enter God’s presence fully, Jesus holds an unchangeable priesthood and opens the way for us. Our hope is not vague. It is tied to a real person in a real place, doing priestly work on our behalf. This is the hope we are to hold fast to.

Hope That Holds Us Because Jesus Is Forerunner

This hope is not merely a feeling - it is anchored in Jesus, who has already entered heaven for us.

He is our forerunner, meaning He goes first to prepare the way, as Acts 1:9‑11 records He was taken up into heaven, and Romans 8:34 confirms He is now at God’s right hand, interceding for us. That means His presence in heaven is more than a fact - it is a promise that we will one day be there too.

To the original readers, this was revolutionary: a human priest entering God’s presence forever? That had never happened before. But now, because Jesus lives forever, He ministers on our behalf, not behind a temple curtain but behind the veil of heaven itself. This is the heart of the good news - He didn’t just die for us; He rose, ascended, and stays with God for us, making our hope sure and real.

Jesus, Our Eternal Priest and the Fulfillment of God’s Promises

The writer of Hebrews ties together ancient promises and priestly duties to show how Jesus fulfills what the old system only pointed to.

Melchizedek, the mysterious priest-king in Genesis 14:18-20, appears without genealogy or death record, making him a living picture of a priest who lasts forever. Psalm 110:4 then declares, 'The Lord has sworn and will not change his mind: You are a priest forever, after the order of Melchizedek.' This was revolutionary - God was promising a new kind of priesthood, not tied to Levi or limited by death.

Hebrews 7:11-28 explains that if the Levitical priesthood could have brought perfection, there would have been no need for another priest. But because it didn’t, God raised up Jesus 'after the order of Melchizedek' - a better priest with a better covenant. Unlike the old priests who offered animal blood and died, Jesus offered Himself once and lives forever, making His priesthood unchangeable. As Hebrews 9:7 says, 'The high priest goes year after year with blood not his own,' but Jesus entered 'not by the blood of goats and calves but by his own blood, thus securing eternal redemption.'

Jesus didn’t just enter heaven as a one-time event; He stays there as our living Priest, continually standing for us before God.

This changes everything for us: we don’t just remember a sacrifice - we live in the presence of a living Savior who intercedes daily. In everyday life, this means we can face struggles with confidence, not fear, because Jesus is still working for us. A church community built on this truth will be marked by deep encouragement, patience, and boldness, knowing their hope is not in rituals but in a real Person in heaven. And when we love others, serve the hurting, or stand firm in trials, we do it knowing our High Priest sees us and speaks for us.
