Inclination

I recently read "The Problem of Pain" by C.S. Lewis.
He thought there might be something like pain in heaven - not an undesirable sort of pain. I don't mind that from my earthly point of view. I derive enjoyment from some forms of pain and it would be strange to be without them. However, to think as Lewis did one would have to regard the Bible passage about there not being any pain in heaven as referring to pain sensations that are undesirable. Is that a stretch?

When deciding if an action is proper to do (when the answer is not clear according to Scripture), I should consider how my personal desires might color my opinion. In some ways it might be easier to decide about an action I don't want to do - it seems like my motives are more likely to be aligned with God's will in such an occasion.
Lewis had the following to say:
"We cannot therefore know that we are acting at all, or primarily, for God's sake, unless the material of the action is contrary to our inclinations, or (in other words) painful... Kant thought that no action had moral value unless it were done out of pure reverence for the moral law, that is, without inclination, and he has been accused of a 'morbid frame of mind' which measures the value of an act by its unpleasantnesss...Yet against Kant stands the obvious truth, noted by Aristotle, that the more virtuous a man becomes the more he enjoys virtuous actions."*

So the more I pattern my life after Christ, the more my desires should be in tune with his will. That's neat.
