At one point in his life, St. Paul asked the Lord three times to take away "the thorn in his side".  God's response was, "My grace is sufficient for you, for power shines forth more perfectly in weakness." Here is what St. Augustine said about this passage. I share this for your reflection.

"In the kind of affliction, then, which can bring either good or ill, we do not know what it is right to pray for; yet, because it is difficult, troublesome and against the grain for us, weak as we are, we do what every human would do, we pray that it may be taken away from us. We owe, however, at least this much in our duty to God: if he does not take it away, we must not imagine that we are being forgotten by him but because of our loving endurance of evil, must await greater blessings in its place. In this way, power shines forth more perfectly in weakness. These words are written to prevent us from having too great an opinion of ourselves if our prayer is granted, when we are impatient in asking for something that it would be better not to receive; and to prevent us from being dejected, and distrustful of God’s mercy toward us, if our prayer is not granted, when we ask for something that would bring us greater affliction, or completely ruin us through the corrupting influence of prosperity. In these cases we do not know what is right to ask for in prayer."

With Jesus we pray: "Father, take away this cup, yet not my will but yours be done."
