Where was Corinth located and what regions lay beyond it?
Corinth was located about halfway west, and the regions still beyond it were Rome, Spain, and Great Britain, and then, as time went by, the New World. This expansion was tied to apostolic authority to preach the gospel in the regions beyond.
Les teaches that Corinth was located about halfway west. When asking what was still beyond, he identifies Rome, Spain, and Great Britain, and then, as time went by, the New World. This connects to Paul's stated aim to preach the gospel in the regions beyond you, not to boast in another man's line of things made ready to his hand. Les explains that the Twelve had no ministry outside the nation of Israel, so Paul's work was virgin territory. If they had already been to Corinth, Athens, Ephesus, or Asia Minor, Paul could not have spoken this way, but they had not.
