Paul experienced something awful in his body, which he called a thorn in the flesh, and he cried out to the Lord,
Concerning this thing I pleaded with the Lord three times that it might depart from me” (2 Corinthians 12:8).
Those certainly were not vain repetitions, but were filled with true meaning. Paul had a major problem, and he went to the One who could fix it, although in this case, the Lord had a reason for leaving it.
Let us learn though, that we should always consult the Lord about our problems.
