What does 2 Corinthians 11:10 mean?

The false teachers in Corinth probably accepted any donations they could get, as was the style of popular ancient orators. As part of their arrogance, they apparently mocked Paul for not doing the same. In fact, Paul was committed not to take anything from the Corinthians, though it was his right to receive support (1 Corinthians 9). Echoing the bad attitude of the false apostles, the Corinthians seem to have resented Paul's refusal to receive donations from them. They misinterpreted this as a sign that he did not love them (2 Corinthians 11:11).

Paul's refusal was based in not wanting anyone to second guess his motive for preaching the gospel. He would allow churches to support his ministry to other churches, just not their own. So, he received donations from the churches in Macedonia while working with the Corinthians (2 Corinthians 11:9), and he received money from the Corinthians to help him travel to other places (1 Corinthians 16:6).

Instead of being ashamed of this practice, Paul boasted about preaching the gospel free of charge. It was one more clear difference between him and the deceivers in Corinth who preached a false gospel about a false version of Jesus. Paul declares that, as sure as the truth of Christ is in him, he will continue to boast about this in the region of Achaia, where Corinth was. This is not prideful boasting on Paul's part, but evidence that he truly represents Christ and that Christ's gospel is true.
