In Acts 7, who was Stephen preaching to?
In Acts 7, Stephen was preaching to the nation of Israel. The context says he addressed Jews, seven years after Pentecost, and recounted Israel's history beginning with Abraham. The language throughout is plain that he was speaking to Israel, not to a Gentile audience.
Les explains that in Acts 7 Stephen is preaching to the nation of Israel, specifically Jews, even though it is seven years after Pentecost. Les notes that Stephen's language is so plain all the way through that he is addressing Jews, and that he goes through Israel's history starting with Abraham. This example shows that not every use of the word church or assembly refers to the New Testament body of Christ, and Stephen's audience was Israel.
