One of the most profound aspects of Tolkien's writing is his ability to weave the themes of creation and apocalypse from Christian scripture into a rich, fantastical world. Through the figure of Eru Ilúvatar, he offers a powerful reflection of God, with Melkor as the rebellious, fallen angel. The final war, echoing the end of days, becomes the ultimate triumph over evil and the restoration of a perfected world, where the Ainur and the Children of Ilúvatar will dwell in harmony.
