None of this is of real concern to God, Who demands only that men and women should repent immediately of their sins. If they do not, they remain in their sin and reap His anger. So, their suffering continues and the fault is entirely their own. Fellow Christians, then, should never sympathise with those who have neurotic symptoms. The same can be said for psychotic symptoms.
Sin is sin.
To seek diagnosis and treatment for these conditions is to try to find an excuse for sinning. I have been told of this or that Christian whose lives, apart from their symptoms, are Godly . Friends, all of us can be Godly in part, and yet retain and practice sin in other parts. Because, for that person, the illness provides some kind of benefit. This benefit can be a cover for sinful activity or thought.
