Hebrews 6:18 says that God gave two unchangeable things, an oath and a promise, so that believers who run to Him for safety can hold firmly to the hope set before them. The verse is a reason for confidence: God cannot lie, so the hope He offers is solid ground for a frightened or weary soul. The author of Hebrews writes it to Christian believers, probably Jewish Christians, who were tempted to drift away from their faith under pressure.
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.

What Hebrews 6:18 Means
The phrase “two immutable things” points to God’s promise and His oath. Both are unchangeable, and the writer explains that it is impossible for God to lie. In ordinary life, people swear oaths to make their word more certain, as the verses just before this one describe. God, in His grace, accepts that human pattern and binds Himself with an oath so His people can see how firmly He means what He has said.
The “strong encouragement” is not a vague pep talk. It is the comfort that comes from knowing the One who made the promise cannot break it. The phrase “who have fled for refuge” pictures someone running to a city of safety, as in the Old Testament cities of refuge. The verse does not promise an easy life or the removal of every trial. It promises that the hope held out in Christ is secure, and that those who take hold of it are not gambling on a God who might change His mind.
The Context of Hebrews 6:18
Hebrews was written to a community that had suffered and was growing tired. The author has just warned them against spiritual sluggishness and urged them to imitate those who inherit the promises through faith and patience. Verse 15 notes that Abraham, after patiently enduring, obtained the promise. The author then moves to God’s own commitment, showing that the same faithful God stands behind the promise to every heir.
Verses 19 and 20 continue the picture. The hope is described as an anchor for the soul, reaching past the curtain into God’s presence, where Jesus has gone ahead as a forerunner and high priest. Read this way, verse 18 is not a standalone comfort. It is the solid base for the anchor image that follows, and it shows that the believer’s hope rests on God’s character and on Christ’s finished work, not on anything fragile in the believer.

A Short Prayer From Hebrews 6:18
Lord, you have given me promises that do not change, and you have not left me guessing about your heart. When my thoughts race and my courage runs thin, remind me that you cannot lie. I run to you for refuge today, and I ask you to steady my hope by your faithfulness rather than by my feelings. Help me take hold of the hope you have set before me, and let your unchanging word be my firm ground. Amen.
