2 Corinthians 12:7-8
7. So to keep me from becoming conceited because of the surpassing greatness of the revelations, a thorn was given me in the flesh, a messenger of Satan to harass me, to keep me from becoming conceited. 8. Three times I pleaded with the Lord about this, that it should leave me.

Tomorrow we will learn the second part of this important verse:

2 Corinthians 12:9-10
9. But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me. 10. For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong.

Here, Paul reminds us that, if our afflictions make us draw close to Jesus, then we should be thankful for each one. It's not easy to do, but if we realize that our weaknesses open us up for God's strength, they are truly gains and not losses.
