Link Hebrews 10:23 to OT promises?
How does Hebrews 10:23 connect with God's promises in the Old Testament?

The Verse Before Us

“Let us hold resolutely to the hope we profess, for He who promised is faithful.” (Hebrews 10:23)


Hold Fast: Our Side of the Verse

• “Hold resolutely” pictures a firm grip, not a casual touch.

• “Hope we profess” points back to the finished work of Christ (Hebrews 10:10,14) and forward to His return (Hebrews 9:28).

• The verse’s weight rests on the final clause: “He who promised is faithful.”


He Who Promised: Faithfulness on Display in the Old Testament

Numbers 23:19—“God is not a man, that He should lie, nor a son of man, that He should change His mind.”

Joshua 21:45—“Not one of all the LORD’s good promises to the house of Israel failed; everything was fulfilled.”

1 Kings 8:56—“According to all that He promised; not one word has failed.”

Psalm 89:34—“I will not violate My covenant or alter the utterance of My lips.”

Isaiah 55:11—“So My word that proceeds from My mouth will not return to Me empty.”

Lamentations 3:22-23—“Great is Your faithfulness.”

These verses provide a historic record that God’s promises were literally fulfilled—land, nation, kingship, preservation, and future restoration.


Promise Threads Woven into Hebrews 10:23

1. Covenant with Abraham (Genesis 12:1-3; 15:5-6)

– Hebrews calls believers “heirs of the promise” (Hebrews 6:17). The same God who counted Abraham’s faith as righteousness now secures ours through Christ.

2. New Covenant Foretold (Jeremiah 31:31-34)

Hebrews 10:16-17 quotes Jeremiah directly, then verse 23 urges confidence because the prophesied covenant is already inaugurated by Jesus’ blood.

3. Davidic Promise (2 Samuel 7:12-16)

– Jesus, the Son of David, sits at God’s right hand (Hebrews 1:3,13). Since God kept this royal promise, our hope in Christ’s future reign is certain.

4. Promise of a Better Rest (Psalm 95; Joshua)

Hebrews 4 connects Israel’s rest in Canaan with the ultimate rest in Christ. God kept the first; He will keep the final.


From Promise to Fulfillment in Christ

Hebrews 6:13-18 recalls God swearing by Himself to Abraham; that same unbreakable oath now guarantees our salvation.

Hebrews 9:15 calls Jesus “the mediator of a new covenant,” the climax of every earlier covenant promise.

• Because every Old Testament promise finds its “Yes” in Christ (2 Corinthians 1:20), believers can cling confidently to the hope held out in Hebrews 10:23.


Practical Takeaways for Today

• Study God’s Old Testament track record; it fuels present perseverance.

• When tempted to waver, recite specific fulfilled promises (e.g., Isaiah 7:14; Micah 5:2; Zechariah 9:9) and their New Testament realizations.

• Anchor your hope not in circumstances but in the proven character of the Promise-Keeper.

• Live expectantly, knowing the God who literally fulfilled past promises will just as literally complete the future ones—resurrection, judgment, and eternal glory.
