Paul prayed three times for the throne to disappear from his life. According to 2 Corinthians 12:8-9, "Three times I pleaded with the Lord to take it away from me. But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness."
Most of us know about the above scripture where God told Paul "My grace is sufficient" after Paul had prayed three times about the thorn in his flesh. However, some people might not recognize the life application associated with that scripture.
To keep Paul from becoming conceited because of his surpassing great revelations, there was given him a thorn in his flesh, a messenger of Satan, to torment him. Three times he pleaded with the Lord to take it away from him. But God said to Paul, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore Paul said he would boast all the more gladly about his weaknesses, so that Christ's power may rest on him. That is why, for Christ's sake, Paul delighted in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when he was weak, then God was strong. (2 Corinthians 12:7-10)
Paul never spoke of the thorn in his flesh again after this conversation with God. Sometimes God chooses to remove the thorn, and sometimes God leaves the thorn alone so His power can be made perfect in our weakness. If a thorn is still in your life after you have prayed for its removal, perhaps God is leaving it there for a reason. God just might be leaving it there so His power can be made perfect in your weakness. If God removed the thorn, He might also remove your anointing as well.
There are some thorns you might want to keep. If God removes the thorn, He will also remove the grace that goes along with the thorn. You have to leave the throne in place before God will say "My grace is sufficient."
