Here is a parable for writers:
Writers are like a man whose wife has compelled him to diet. One night he wakes with a craving for chocolate. He turns softly in bed to see if his wife is deeply asleep, then slowly slides out of bed and down the hall to the kitchen. He wrestles gently with the wrapper, slides the chocolate down his throat, regrets the sweetness. Somewhat brazenly he returns to bed, only to find that all is still very quiet.
In a nutshell, writers, and specifically writers trying to create for God's glory often write hesitantly because of fears from many directions. These fears create a lack of confidence that stifles our energy and we give up, only to make another run at it some time later, with similar results.
When we think about writing, the greatest obstacle that we face is not one of flat characters, uninspired language, or any other technical element. It is not practical considerations such as how to make a living. Rather the greatest obstacle between us and God-honoring art is fear. We fear that that we would spend hours on a piece that is our soul, only to have those outpourings flutter through the world like a plastic grocery bag flung through autumn and eventually blown up against a chain link fence to trap leaves and garbage, totally unnoticed.
Even before that terror, we fear that when we sit to write, nothing will bubble up from the dark unknowns of creativity—that we will sit like a barren woman longing for a child. What would it say about us if the well of creativity has run dry? What if there is nothing left this time? Is it not better to rest on the successes of the past?
Then there is the fear that even if writing happens 'successfully' the writing itself will have no real value, that it won't matter for anything in the long run. For the Christian, there is always that question lurking in the shadows, "Is what I am doing worthwhile in an eternal sense?" And this question, while valid and important in an age wholly given over to trivialities and the desperate search for novelty, keeps us in doubt as we approach our craft. Doubt of this kind will slow our thoughts and inspiration to a trickle, and knowing this, we fear even more.
