Acts 28:23-29 :

When they had appointed him a day, many people came to him at his lodging. He explained to them, testifying about the Kingdom of God, and persuading them concerning Jesus, both from the law of Moses and from the prophets, from morning until evening. Some believed the things which were spoken, and some disbelieved. When they didn’t agree among themselves, they departed after Paul had spoken one word, “The Holy Spirit spoke rightly through Isaiah, the prophet, to our fathers, saying,

‘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.
For 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,
and I would heal them.’

“Be it known therefore to you, that the salvation of God is sent to the nations. They will also listen.”

When he had said these words, the Jews departed, having a great dispute among themselves.

Once again the Jews in general didn’t listen to the message although “some believed the things which were spoken.” As a result, God’s word was to go out to the whole world giving each person a chance to learn about the God of the Jews and about their Messiah Jesus. God planned for this all along since there are no surprises to God. His plan was for the entire world to be brought back to himself.

Notice, also, that Paul makes it clear that the Holy Spirit was speaking through Isaiah in the Bible. Isaiah as well as the whole Bible was actually spoken by the Holy Spirit. That’s what makes it special. Even though the Bible had authors such as Isaiah, God was able to have them willingly write what He put in their hearts to write for Him. It should not come as a surprise to us that the Bible is the number one best selling book of all time in the world.
