No one ever said "God wants me to have incurable tumors." It's always someone else who should suffer. This is the opposite of the early Christian message. I would almost say, if you are not helping people to the point of discomfort, you are missing the point of Christianity.
So much for "Whatever you did for the least among you, you did also for me". Remember they now say that the Sermon on the Mount is too liberal. They don't agree with Jesus's message because they have people they don't like. They have enemies they want to hurt.
