It matters that we know that Paul's thorn was not a sickness, for he had the power in Christ to appropriate his healing. God, the perfect Father would never say no to healing! Rather, He said no to removing the thorn of persecution, because persecution is a promise for all who serve God. He gives us the strength to endure it, just as He promised Paul.
God's word tells us that the thorn is a person---in every single instance in the entire volume of the book. Never is it a sickness or anything else.
Believing erroneously that Paul's thorn was some kind of physical ailment gives Christians the excuse to believe a lie---that it is somehow God's will that His children be sick.
