What does 2 Corinthians 11:12 mean?
Opponents in Corinth are attempting to seduce the Corinthians away from their loyalty to Paul. They have called attention to Paul's unimpressive physical presence and speaking skills (2 Corinthians 10:10). They have questioned whether a true servant of God would really experience so much suffering (2 Corinthians 6:3–10). They have also apparently mocked his commitment not to take any personal funding from the Corinthians, something they are happy to do (2 Corinthians 11:7).Paul points to this difference between him and fraudulent "apostles" as evidence they are false in their "boasted mission." Their claim is that Paul is a false representative of Christ and that they are the real apostles. Paul shows in this verse, though, that they do not work on the same terms he does. He celebrates in Christ that he was able to preach the gospel free of charge. The deceiving ones cannot boast about that, because they gladly take the Corinthians' money to preach a false gospel to them. In fact, money may be the entire point of their false teaching.
Paul declares that he will continue to preach about Jesus for free—and continue to exult in it—to undermine his opponents' false claims to be like him. If they are truly like him, he implies, they should also refuse the Corinthians' money. He knows they will not do that.
