Universalism(Hope I spelled this right)

In the previous post we talked about God hearing non-Christian prayers. Well, in the Chronicles of Narnia CS Lewis brings up an interesting idea in the last book. There is a guy who worships the god of his country, who is not God. Yet he worships him in devotion, boedience, and love. This guy ends up in heaven with the people from Narnia. That was the butchered version from teh book, The Last battle I think. Well, do you think that someone like this can go to heaven?
