God has given you a gift to write, and you're doing an excellent job at pecking away your passions, thoughts, and creativity. But how do you incorporate Him? How do you keep it real, without losing your audience or come off as "preachy"?
When God inspires you, He inspires the creativity. That's the wonderful thing about being a writer. Because He is in you, you are in Him. That means that whatever you write, allow Him to shape your writing. It may not necessarily come out in verbatim scripture form, but it shines just as bright.
Remember the Word of God is to draw us closer to Him. Examine your purpose (why) and your goal (what you want to achieve) in your writing. Align those two principles with what God's word says, and watch how He will inspire and impart scripture into both your "why" and your "what."
Being a Christian writer isn't about quoting scriptures throughout your work; it is about being an agent of change to Godly living. Something written on those pages has to be a part of a change that takes place in the reader's heart and mind that causes them to turn away from their fleshly desires, and want to know God even the more.
Fictional writing isn't just about entertaining, it is about making a difference such as: Encouragement, Motivation, or even bringing Repentance to your reader. What scriptures and examples of scriptures align with your "why" and your "what?" What difference does God want you to make in your writing for Him?
To incorporate God is to incorporate truth, which is to incorporate a chance to make a difference. To incorporate Him is to seek Him during the story plot stages, the manuscript development, the character analysis, and the climactic themes. Ask Him what is it that He wants you to tell your readers? Study to show your own self approved in being a storyteller for Him. As you incorporate Him in your own daily life, He will incorporate Himself in the life of your writing.
