Acts 28:25-28 Meaning: The Spirit's Warning and a New Invitation
25When they didn’t agree among themselves, they departed after Paul had spoken one message: “The Holy Spirit spoke rightly through Isaiah the prophet to our fathers,
26saying, ‘Go to this people and say, in hearing, you will hear, but will in no way understand. In seeing, you will see, but will in no way perceive.
27For this people’s heart has grown callous. Their ears are dull of hearing. Their eyes they have closed. Lest they should see with their eyes, hear with their ears, understand with their heart, and would turn again, then I would heal them.’
28“Be it known therefore to you that the salvation of God is sent to the nations, and they will listen.”
25And when they agreed not among themselves, they departed, after that Paul had spoken one word, Well spake the Holy Ghost by Esaias the prophet unto our fathers,
26Saying, Go unto this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see, and not perceive:
27For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them.
28Be it known therefore unto you, that the salvation of God is sent unto the Gentiles, and that they will hear it.
25And when they agreed not among themselves, they departed after that Paul had spoken one word, Well spake the Holy Spirit through Isaiah the prophet unto your fathers,
26saying, Go thou unto this people, and say, By hearing ye shall hear, and shall in no wise understand; And seeing ye shall see, and shall in no wise perceive:
27For this people’s heart is waxed gross, And their ears are dull of hearing, And their eyes they have closed; Lest haply they should perceive with their eyes, And hear with their ears, And understand with their heart, And should turn again, And I should heal them.
28Be it known therefore unto you, that this salvation of God is sent unto the Gentiles: they will also hear.
25And not being agreed with one another, they were going away, Paul having spoken one word--`Well did the Holy Spirit speak through Isaiah the prophet unto our fathers,
26saying, Go on unto this people and say, With hearing ye shall hear, and ye shall not understand, and seeing ye shall see, and ye shall not perceive,
27for made gross was the heart of this people, and with the ears they heard heavily, and their eyes they did close, lest they may see with the eyes, and with the heart may understand, and be turned back, and I may heal them.
28`Be it known, therefore, to you, that to the nations was sent the salvation of God, these also will hear it;'
25And being disagreed among themselves they left; Paul having spoken one word, Well spoke the Holy Spirit through Esaias the prophet to our fathers,
26saying, Go to this people, and say, Hearing ye shall hear and not understand, and seeing ye shall see and not perceive.
27For the heart of this people has become fat, and they hear heavily with their ears, and they have closed their eyes; lest they should see with their eyes, and hear with their ears, and understand with their heart, and be converted, and I should heal them.
28Be it known to you therefore, that this salvation of God has been sent to the nations; they also will hear [it].
Meaning in one sentence
Paul quotes Isaiah to show Israel's hardened heart and announces God's salvation is now sent to the Gentiles, who will listen.
Context
This is Paul's final recorded meeting with Jewish leaders in Acts. He has arrived in Rome as a prisoner, yet he gathers the local Jewish community to explain his mission and his hope. For an entire day he argues from the Law and the Prophets, pointing to Jesus. Some believe; others do not. As the meeting breaks apart in disagreement, Paul makes one last declaration. He reaches back to the prophet Isaiah, quoting words that Jesus himself had used when facing similar rejection. Paul says these words came from the Holy Spirit. Then he turns the corner: because the message was not received here, it is sent to the Gentiles. This moment closes a long pattern in Acts and opens the door wide to every nation.
Key Words
Three Greek words hold the weight of this passage. First, rhēma, Paul speaks 'one word' or 'one declaration.' This is not a long speech. It is a single, heavy statement drawn from Scripture, intended to land like a final stone. The same word is used for every word that comes from God's mouth (Matthew 4:4). Paul is not adding his own opinion; he is delivering a settled verdict.
Second, epachunthē, the heart 'has grown callous.' The original verb means to thicken or make fat. It describes a soul that has become dull and heavy, no longer sensitive to God's touch. This is not something God does to unwilling people. It is what happens when we keep turning away. The callous forms slowly, a little at a time.
Third, sōtērion, 'salvation.' Paul calls it 'this salvation of God,' as if pointing to the very thing standing in front of them. It is not an abstract idea. It is a gift that has been delivered, ready to be received. And because it can be rejected, it can also be taken elsewhere. That is what Paul announces next.
How Christians Read This Verse
Christians across traditions have read this moment as both a warning and a hinge. Reformed commentators like Calvin see the quote as a 'mallet' meant to shatter human pride and a sovereign act of God in judgment. Wesley and other Methodist writers emphasize that the blindness is a consequence of persistent human resistance. Catholics often note how the Holy Spirit speaks through the prophet, affirming that Scripture carries divine authority. Orthodox readers may focus on the tragedy of the calloused heart and the hope that repentance remains possible. All traditions agree that this passage marks a decisive turn: the gospel now goes freely to the Gentiles, fulfilling the ancient promise that Abraham's blessing would reach all nations.
A common misunderstanding
A common misreading is that God deliberately hardened the Jewish people so they could never repent. In fact, the text says 'their eyes they have closed', the people themselves are the ones shutting their eyes and ears. The judgment described is God giving them over to the callousness they have already chosen. Paul's sorrowful tone shows this is not a rejection without cause, but a response to persistent refusal.
Living This Out
You might be in a season where God's word feels distant or heavy. The calloused heart does not happen overnight. It grows slowly, one small refusal at a time: choosing not to listen, not to look, not to turn. This week, ask yourself where you might be closing your eyes. It could be a relationship you are avoiding, a truth you would rather not face, a step you keep putting off. Then remember the rest of the verse. When one group stops listening, God does not pack up his salvation. He sends it somewhere else. The same gospel that some resist is the very gospel that others are desperate to hear. You can still be part of that hearing.
Main takeaway: God's salvation is sent; where hearts harden against it, He carries it to those who will listen.
For Families
For ages 5, 8
Sometimes we do not listen when someone is talking to us. God wants us to listen to Him. Even when people do not listen, God keeps talking because He loves everyone.
For ages 9, 12
Paul quoted a very old warning from Isaiah. The people had heard God's message many times but still closed their eyes and ears. Their hearts got hard, like a thick callous. That can happen to anyone who ignores God over and over. But the good news is, God did not give up. He sent his salvation to other people who were ready to hear. You get to decide whether your heart will be soft or hard toward God.
Questions People Ask
Why did Paul quote Isaiah 6:9-10 in Acts 28?
Paul used these verses to show that the pattern of hearing without understanding was not new. The prophet Isaiah had described it centuries earlier, and Jesus himself had quoted the same words when explaining why he taught in parables. Paul was saying, 'This is what God's Spirit already told you would happen.'
What does 'waxed gross' or 'callous' mean in this verse?
The Greek word 'epachunthē' means to become thick or fat. It describes a heart that has grown dull and insensitive. It is not a sudden condition but the result of repeated refusal to listen, like a callus that forms on skin from constant friction or pressure.
Does this verse mean God has permanently rejected the Jewish people?
Christians interpret this differently across traditions, but most agree that this passage describes a turning point, not a final rejection. Paul later writes in Romans 11 that God has not cast away his people and that they may still be grafted back in. The immediate context is that Paul is turning to the Gentiles because many Jews in that time and place have refused the message.
How does the Holy Spirit speak through Isaiah the prophet?
This verse directly states that the Holy Spirit spoke through the prophet Isaiah. Many Christians see this as evidence that Scripture is inspired by God. The Holy Spirit did not replace the prophet's personality but moved him to speak God's exact message. Second Peter 1:21 says holy men of God spoke as they were carried along by the Holy Spirit.
What is the significance of Paul saying 'one word' before quoting Isaiah?
The Greek word 'rhēma' means a single spoken declaration. Paul was not giving a long farewell speech. He delivered one final, weighty statement drawn from Scripture. It was a kind of verdict that wrapped up the entire day's discussion and justified his decision to turn to the Gentiles.
