I think the issue is did God call Thorn to be a minister. What he is good at does not matter. If he doesn't have the knack for it in the natural, the Lord is more than able to make up for it as Thorn obeys Him. Those without the natural ability are the best kind, if they surrender to Christ, because they have to depend on the Lord to do the work since they can't. People who can do it on there own power can more easily do it in the flesh and can more easily start thinking that they do not need God in this ministry. Those that don't have the knack must seek the Lord for His power to do it through them. :) I would rather see the Lord's power than someone operating in the flesh.
