To suggest illness is caused by 'sin' is a slap in the face to all those billions of people whose illnesses have nothing to do with behaving unwisely. My husband's brain aneurysm was due to no fault on his part. My osteoarthritis, which started in my 30s has nothing to do with gluttony. My badly fractured arm was caused by my stupidity in walking up the bridle path after heavy rain. Whilst that was very unwise, I doubt it could be termed a 'sin'.
