Below is a prayer for writing adapted from a prayer of Walter Wink found in his book Just Jesus (page 23 for those interested). I found Wink’s words a powerful reminder about our need to rely on the “muse” of the Holy Spirit when writing.
On this beautiful summer day, Lord, I bring my whole self, including my questions and confusions to you, and offer myself to be used by you in the process of writing. Deliver me from egocentric plots. Give me courage to rewrite with perfection. I do commit myself from you, O God, in life, in death. I commit myself to the truth, your truth. I will not be cowed by pain or use it as an excuse for resistance. I will not bend to laziness or ignorance. I will try to hold myself open to the depths. I ask for images and metaphors to flow as I write. I ask for help in revising this writing, to make it really readable. I ask for patience to do it right. May my writing and living honor your name and not my own. Amen.
