Hebrews 6:18 teaches that God has given believers two unchangeable realities, his promise and his oath, which make it impossible for him to lie, so that those who have run to him for safety can hold firmly to the hope set before them. The writer is speaking to Christians, most likely Jewish believers facing pressure and discouragement, and he points them back to the way God confirmed his promise to Abraham.
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 his oath. Because God cannot change his mind or break his word, these two things stand firm. The writer uses the picture of people who swear an oath to settle a dispute, since an oath ends the argument. God, who is greater than anyone, chose to bind himself with an oath so that his people could be certain of his intentions.
“It is impossible for God to lie” is not a statement about God being unable to do something he wants to do. It describes his truthful character. The writer is saying that God’s words are fully reliable, and anyone who trusts them has solid ground to stand on.
The verse does not promise that life will become easy or that every prayer will be answered in the way we expect. It promises that God’s word is trustworthy and that his people can rely on his character when they feel weak or afraid.
The Context of Hebrews 6:18
Hebrews is a letter written to Christians who were tempted to drift away from their faith or to lose confidence in Jesus. The author is not named in the letter itself, and while early tradition often connected it with Paul, most scholars do not hold that view today. The original readers seem to have been under strain, and the writer repeatedly urges them to keep going.
Just before verse 18, the writer recalls how Abraham waited patiently and received the promise. Verse 17 explains that God added an oath so that the heirs of that promise would see how firmly his purpose stands. Verses 19 and 20 then describe the hope as an anchor for the soul, which reaches behind the curtain to Jesus, who has gone ahead as our high priest. The verse reads differently when you see that it is part of this larger picture of God securing a hope that holds.

Lord, you have not left us to guess whether your promises are true. You have given us your word and even your oath, so that we could be certain of your faithfulness. When we feel weak or afraid, help us run to you for shelter and hold firmly to the hope you have set before us. Teach us to trust your character more than our circumstances. Amen.
