"And if you read 2 Cor 1-11 you'll see that it worked!"
Ah, you ruined it for me :-)
I am working my way through the NT, one epistle a week, and next week is 2 Corinthians, this week, 1 Corinthians. Amazing that Paul could have addressed much of 1 Cor. to the United States.
Regards
2 Cor 2:1-11 to be more exact. Particularly around vs 5.
Talk about a seaport city. Corinth was a double seaport city!
