In 2 Cor 11, Paul gives reasons to trust in his teachings, rather than " be led away from your pure and simple devotion to Christ". He warns those who would "believe whatever anyone tells you, even if they preach about a different Jesus... or a different kind of gospel". In this passage (and others) Paul describes himself as a weak speaker. So he asks not to be judged by his presentation abilities, but rather the content of his teaching. In this way, He "cut off opportunity" from those who desire to be regarded as doing the same work of the Lord in preaching the gospel. Paul warns believers not to be impressed and easily deceived by the fancy talk of such false teachers. Regarding himself, Paul boasted in his weakness in order to bring glory to God.
