We've been reading in the New Testament as a family lately, and Paul has some great advice and counsel that's still applicable today. In his letter to the church in Corinth, he talks about a thorn in the flesh. 2 Corinthians 12:7-9 7 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. 8 For this thing I besought the Lord thrice, that it might depart from me. 9 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. It's kind of a moot point to speculate what Paul's particular thorn might have been, but I've often wondered. More importantly: what is God's purpose in giving his children such difficult stuff to learn? Why does life have to be so hard?
