2 Corinthians 11:29 Meaning

27In weariness and painfulness, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness.

28Beside those things that are without, that which cometh upon me daily, the care of all the churches.

29Who is weak, and I am not weak? who is offended, and I burn not?

30If I must needs glory, I will glory of the things which concern mine infirmities.

31The God and Father of our Lord Jesus Christ, which is blessed for evermore, knoweth that I lie not.
