Ok... between your own enjoyment, and everyone else's blogs about this story, I'm not gonna bore you with some long post. But, we have to ask "Why is Les Miserables still important for the Church?" I will only let the testimony of the beloved priest from the story, Myriel, speak here:
As you could've guessed, this is a story of the miserable, the weak, and the low in life. It is also the story of the same miserable and weak, learning not to be strong... but to live in God's acceptance. As you probably noticed from this latest adaptation, whether it's Valjean's unjust mistreatment by society, Fantine's heart-wrenching plummet into prostitution, or Galvroche's cold execution, the story relentlessly declares the current state of our world. However, this isn't the whole story, as Hugo continues. It is the story of Yahweh's adoption of His children.
So, this timeless story is a testimony to spur His children to share the Gospel of adoption, both temporal and and eternal. Enjoy, and be blessed.
