Hebrews 6:18 says that God’s promise and oath give believers a strong encouragement to hold onto the hope set before them. The verse is a reason to take refuge in God’s unchanging word, because God cannot lie and has bound himself to his promise with an oath. The writer of Hebrews, traditionally identified as an unnamed author writing to Jewish Christians, is pointing back to God’s dealings with Abraham as the basis for this confidence.
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” refers to God’s promise and the oath he added to it. Something that cannot change is one that stays the same no matter the pressure or circumstance. The writer says that God gave both his word and his oath, so that people would have two solid grounds for trust rather than one.
The phrase “in which it is impossible for God to lie” explains why these two things are so firm. Human beings sometimes break promises, but God’s nature is truth, so his word cannot be false. The verse is not saying that everything that happens to believers will feel comfortable. It is saying that the promise itself rests on the character of a God who cannot deceive.
The verse is also careful about what it does and does not promise. It speaks of “strong encouragement,” not of an escape from trouble or a guarantee of an easy life. It describes the hope believers hold as something they grab hold of, which implies effort and perseverance, not passive comfort.
The Context of Hebrews 6:18
The letter to the Hebrews was written to Christians who were tempted to drift back toward old patterns of life and faith, possibly under pressure from their community or from hardship. The author warns them about spiritual complacency in the verses just before this passage, and then turns to encourage them with the reliability of God’s promise to Abraham. Verse 15 notes that Abraham patiently endured and obtained the promise, which sets up the example the readers are meant to follow.
Verses 16 and 17 explain the logic of an oath. People swear by something greater than themselves to settle disputes, and God, to show how firmly he holds to his purpose, added an oath to his promise. Verse 19 then goes on to describe this hope as an anchor of the soul that enters into the inner sanctuary, and verse 20 names Jesus as the forerunner who has already gone there. Read in that setting, Hebrews 6:18 is not a general pep talk but the foundation for the whole argument about Christ’s priesthood.
