You never know how God is using you.
It's so amazing! I'm thinking so hard about my characters and their lives, why the hero and the heroine do what they do, why the adversary hates them so much, and God shows me things, shows me how what I've written mirrors His truth, though I knew it not.
My protagonist is a black lizard, a creature seething with hate, full of a rage that gives him terrible power. I realized, all of a sudden, that I didn't know why he was fighting this battle against the faeries anyway; what did he have against them? Why did ruling them and overcoming them mean so much? I have a "bad-guy", but no reason behind him.
It was when I was asking myself about this "bad-guy", that I realized, with a sudden, electrifying thought, that God was writing his own message into my writing. I was trying to understand my character, and suddenly God showed him to me, full of new meaning. How this works in my story I can't disclose, but I had to share this wonderfully heartening revelation.
God is working in us, and through us. No matter how much we fail or achieve in ourselves, in the end, He is using our efforts for His glory.
Praise be to Him!
