Quite a few of my stories end up having a verse or two that runs through them, strengthening the characters. Or challenging them. But I don't often start writing knowing those scriptures are going to be the ones my fingers add to the writing as I type. And yes, my brain really does work that way when writing. 
That being said, however, as I plot and imagine scenes for my next story, Beauty School and the Beast, I have several scriptures that keep popping up in my head. And I love that this novel is starting with scripture instead of just allowing the Spirit to move as I compose.  The scriptures are perfect too. Because my story is about a character too focused on the outward appearance and not focused enough on the inside. Just like the original story. Too wrapped up in self and not enough in love.
First, I Peter 4:3-4. "Do not let your adorning be external—the braiding of hair and the putting on of gold jewelry, or the clothing you wear— but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious."
Can't you just see the character sitting in a church service and being hit with that one? Of course, it won't penetrate at first. We can't have the character change ways too quickly.
Then, Colossians 3:12-14. "Therefore, as God’s chosen people, holy and dearly loved, clothe yourselves with compassion, kindness, humility, gentleness and patience. Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you. And over all these virtues put on love, which binds them all together in perfect unity."
Yep. We've got to focus more on the inward than the outward. And it's not always an easy lesson to learn. My poor character is in for quite an ordeal in this book, but if these scriptures can wiggle their way into the heart, there's hope yet that that character will emerge more beautiful than beast. 
What other Scriptures can you think of that would apply well to a Beauty and the Beast retelling? I'm itching to get some words on the page for this one, but have several edits to get through first. But soon!
