Continuing the conversation about the Kingdom, Paul again turns to the theme of poverty and true wisdom. Contrasting his own position with the position of those who occupied prominent places in the Corinthian church, the apostle again reminds the Christians of Corinth of what he had already said more than once both to them and to his other fellow believers: the Kingdom is not of this world, and therefore it cannot in any way triumph in our world, which has not yet been fully transformed, before its complete transformation at the end of time (vv. 8-14). And the point is not that Paul did not want to see the Corinthian Christians as they imagined themselves to be, but that before Christ's return this could be achieved only by rejecting that fullness of the Kingdom which, in a world not yet transformed to the end, is incompatible with any triumph.
The apostle reproaches no one; he only reminds the Corinthian church of certain fundamental things without which there can be no question of any life in the Kingdom (v. 14). And when he warns the Christians of Corinth that he can come to them not only with love, but also with rebuke ("with a rod," v. 21), the apostle's purpose is not at all a desire to shame or unmask anyone. It is simply that, seeing what is happening in the Corinthian church, Paul could not fail to understand that he would have to confront very serious spiritual problems, that many of the local church leaders are, in essence, not witnesses of Christ and the Kingdom at all and are leading their community in a completely wrong direction. He knows that these leaders have ceased to be witnesses and have become simply teachers, like those who in those days could be found in abundance in any rabbinic or philosophical school. And he knows that such teachers, whose whole strength lies in skillful command of speech, will inevitably retreat before the true power they cannot resist: the power of the Kingdom, which every true witness manifests (vv. 18-20).
