Luke 1:70 tells us that the promises God makes are not new inventions. The verse says God kept his word in the coming of salvation exactly as he had spoken it long before, through the prophets of Israel. The words are spoken by Zacharias, the father of John the Baptist, as he praises God after his son’s birth, and they are addressed to the people of Israel and to anyone who hears the good news of God’s work.
(as he spoke by the mouth of his holy prophets who have been from of old)…

What Luke 1:70 Means
The phrase “as he spoke” points to God’s own words as the source of what is happening. Zacharias is not claiming that God has changed his mind or is improvising. He is saying that the arrival of a redeemer from David’s house fulfills what God announced through his messengers. The word “prophets” means those who spoke God’s message to Israel over many generations, and “from of old” reminds us that this promise has been spoken for a long time, not just recently.
The verse does not promise that every hope we hold will arrive on our timetable or in the form we imagine. It speaks to God’s faithfulness to what he has already said. It also does not explain every detail of how the promises will unfold. What it does is anchor our trust in a God whose word has a track record, so that when we wait, we are waiting on someone who has kept his word before.
The Context of Luke 1:70
Luke wrote the Gospel that bears his name, and the book of Acts, to a reader he addresses as Theophilus, probably a Gentile believer or inquirer who wanted a careful and orderly account of what had been fulfilled among the followers of Jesus. The opening chapter is rich with Jewish worship and expectation: an elderly priest in the temple, a barren woman who conceives, a young woman told she will bear the Son of the Most High. Luke writes in a style that echoes the Greek Old Testament, which makes the psalm-like praise in this section feel very much at home in Israel’s story.
Just before verse 70, Zacharias blesses God for having “visited and redeemed his people” and for raising up “a horn of salvation” in the house of David. Just after it, he speaks of salvation from enemies and of God’s covenant oath to Abraham. Reading verse 70 in that sequence shows that the prophetic words are not a side note. They are the thread that ties the promises to David and Abraham to the birth of John and the coming of Jesus, which is why the verse reads as a summary of God’s long faithfulness rather than a standalone claim.
Key Phrases in Luke 1:70
Romans 4:20-21
20 Yet, looking to the promise of God, he didn’t waver through unbelief, but grew strong through faith, giving glory to God, 21 and being fully assured that what he had promised, he was also able to perform.
(WEB)
Paul describes Abraham, the one named in Zacharias’s words, as someone who grew strong in faith and was fully convinced that God was able to do what he had promised. This connects closely to Luke 1:70 because it shows the same confidence in God’s word that Zacharias expresses when he speaks of promises fulfilled.
Hebrews 10:23
Let us hold fast the confession of our hope without wavering; for he who promised is faithful.
(WEB)
The writer of Hebrews urges believers to hold firmly to the hope they profess because the one who promised is faithful. That is the same logic that stands behind Luke 1:70, where the faithfulness of God to what he spoke through the prophets becomes the foundation for present confidence.
A Short Prayer From Luke 1:70
Faithful God, you have spoken, and your word has not fallen to the ground. Thank you for keeping your promises across the generations, for speaking through the prophets, and for bringing your saving work into the world at the right time. When I am tempted to think that my waiting has been forgotten, remind me of your long and steady faithfulness. Help me to trust what you have already said, and to walk in that trust today. Amen.
