2 Corinthians 12:5

Of such a one will I glory: yet of myself I will not glory St Paul desires to put the fact in the background that it is of himself he is speaking (see next verse). He has been compelled by the folly and perversity of certain among the Corinthians to touch on these proofs of Divine favour, but he just glances at the topic and passes it by; nay, he even seems to make a distinction between himself as he is and the man once so highly glorified by God, and returns to a kind of boasting more in accordance with his own sense of propriety. So he expatiates on the thorn in the flesh as an instance of how human weakness does but serve to manifest the power of God.
