We Have Met The Enemy And He Is Us (Part 2)
Paul knows and affirms to the church at Corinth that the pagan world surrounding them was comprised of the sexually immoral, swindlers, the greedy, revilers, drunkards, and idolaters, but they (and the culture they created) were not his concern. What concerned Paul was not what was happening out there but what was happening in here, in the Corinthian congregation. It was not the gross sexual immorality of the pagans in Corinth that kept him up at night. Continue reading →
