jesus can cure: asperger's, autism, other forms of retardation, arthritis, the common cold, allergies, and cripples.
jesus refuses to cure: aids, cancer, any form of sexually transmitted disease, alzheimer's, or parkinson's.
jesus doesn't cure those because only evil wicked people get such diseases and as such is why they get such diseases and conditions. those who don't accept jesus christ are also doomed to forever have asperger's, autism, retardation, arthritis, the common cold, allergies, and will never walk.
those who accept jesus...well you still won't be cured but you'll imagine you feel better and feeling good about yourself is what counts in the end anyways. because you're already dead by the end so how you feel after that point doesn't mean jack.
