Paul told the Jews that non-Jews would believe the gospel.

Acts 28:23-31

23 So they talked with Paul and decided that they would come back on another day to hear him. When that day arrived, those Jews came back to the place where Paul was staying, and they brought more Jews with them. Paul talked to them from morning until evening. He talked to them about how God wants to rule people’s lives [MET]. He tried to convince them that Jesus is the Messiah by reminding them what Moses and the other prophets had written [MTY]. 24 Some of those Jews believed that what was said by Paul {what Paul said} about Jesus was true, but others did not believe that it was true. 25 So they began to argue with one another. Paul realized that some of them did not want to listen to him, so when they were about to leave, he said, “The Holy Spirit said something to your/our(incl) ancestors. He spoke these words to Isaiah the prophet, and what he said is also true about you:

26 Go to your fellow Israelites and tell them,

‘You repeatedly listen to the message of God, but you never understand what God is saying.

You repeatedly look at and see the things that God is doing,

but you never understand what they mean.

27 God also said to the prophet,

These people do not understand, because they have become stubborn.

They have ears, but they do not understand what they hear,

and they have closed their eyes because they do not want to see.

If they wanted to obey what I say to them, they might understand what they see me doing and what they hear me saying.

Then they might turn from their sinful behavior and I would save them.’

28-29 28-29That is what God said to the prophet Isaiah about our ancestors. But you Jews today do not want to believe God’s message. Therefore, I am telling you that God has sent to the non-Jews this message about how he saves people, and they will listen and accept it!”

30 For two whole years Paul stayed there in a house that he rented. Many people came to see him, and he received them all gladly and talked with them. 31 He preached and taught people about how God could rule their lives [MET] and taught them about the Lord Jesus Christ. He did that without being afraid, and no one tried to stop him.
