A thorn in the flesh often pins back the shroud of selfishness
that keeps us from seeing the face of God.

 I was given a thorn in my flesh, a messenger of Satan, to torment me…
That is why, for Christ’s sake, I delight in weaknesses,
in insults, in hardships, in persecutions, in difficulties.
For when I am weak, then I am strong.
2 Corinthians 12:7, 10, NIV
