The Silmarillion

No theme may be played that hath not its uttermost source in me....
- The Silmarillion, J.R.R. Tolkien

The first chapter of The Silmarillion is the creation story, full of beautiful description and imagery. It is breathtaking. You should read it. Ilúvatar is the Creator, and he creates the Ainur who sing the songs of harmony weaving many themes that become one song of creation. A heavenly realm in sync with one another which increased beyond hearing, and flowed from depths to heights.

But as we know from our creation story, a dark theme enters into the song. In this case, it is Melkor who begins to change the music to a loud, clanging sound with intentions to distract and disrupt. A war of music ensues with Melkor seemingly winning the battle, until....
Ilúvatar stands and he seems to smile. At the raise of his left hand and then his right, a new song was created in the midst of chaos. Melkor's theme was loud and only meant to 'drown the other music by the violence of its voice, but it seemed that its most triumphant notes were taken by the other and woven into its own solemn pattern."

This is what God does in our lives and in our world. This beautiful retelling of creation by Tolkien is so enriched with imagery and depths of music with the Creator always having the final say when it seems like evil is gaining power and control. The Creator uses the darkness of Melkor's theme, interweaving it into the music, not letting it take over, but melding it all together in the whole of creation.

It is just like God to take something dark and make it into something beautiful.

That is the story of God and what He does for us. Sub-created by Tolkien.
