And he said unto me, My grace is sufficient for you: for my strength is made perfect in weakness. Most gladly therefore will I rather boast in my weaknesses, that the power of Christ may rest upon me.
All Commentaries on 2 Corinthians 12:9 Go To 2 Corinthians 12
Tertullian of Carthage
AD 220
Still, we must realize that as you cannot have a persecution without evil on the part of the devil or a trial of faith without a persecution, the evil that seems required for the trial of faith is not the cause of persecution but only its instrument. The real cause of the persecution is the act of God’s will, choosing that there be a trial of faith; then there follows evil on the part of the devil as the chosen instrument of persecution which is the proximate cause of the trial of faith. For in other respects too, insofar as evil is the rival of justice, to that extent it provides material to give testimony of that of which it is a rival, and so justice may be said to be perfected in injustice, as strength is perfected in weakness. For the weak things of the world are chosen by God that the strong may be put to shame, and the foolish things of this world to put to shame its wisdom. Thus even evil may be used that justice may be glorified when evil is put to shame.
