Does the Acts account address any words to the Gentiles?
The Acts account contains no language addressed to Gentiles; its message is directed entirely to the nation of Israel. Peter and the eleven confined their ministry to the Jew, while Paul and Barnabas later went to the Gentile. The language is so plain a sixth grader can understand.
Les explains that when they come into the Acts account, it is only to the nation of Israel. He emphasizes that the language is so plain a sixth grader can read it and understand that there is no language in there addressed to Gentiles; it is all to the Jew. This ties back to Jesus' words to Peter, "feed my sheep, the house of Israel," and to Matthew chapter 10 where Jesus had just chosen the twelve. The stark difference is that Peter and the eleven confine their ministry to the Jew, while Paul, Barnabas, and later Silas go to the Gentile.
