<P> Thorn in the flesh is a phrase of New Testament origin used to describe a chronic infirmity, annoyance, or trouble in one's life, drawn from Paul the Apostle's use of the phrase in his Second Epistle to the Corinthians 12: 7--9: </P> <P> And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure . For this thing I besought the Lord thrice, that it might depart from me . And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness . Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me . (KJV) </P>
