I just finished reading a series by Karen Hanock called Legends of the Guardian King. The books were allegorical fantasies loaded with adventure. One take away I had from the book was my shadow versus Eidon's (God's) light. In the story, the main character Abramm often struggled with his shadow keeping him from being able to fully use Eidon's light. Fear, anger and disbelief would allow the shadow to take control and Eidon's light would be covered. Many times his life would be at stake and victory would only come as he emptied himself before Eidon allowing the light to take control.
In my own life, I often let the shadow of fear, unbelief, or even anger cloud the light of Jesus in me. Instead of taking every thought captive for obedience to Christ (IICor 10:5), the thought takes over until it has control of my emotions and I head the wrong direction. Lately I have been learning to take the advice of Is 26:3 (NLT) which says " You will keep in perfect peace all who trust in you, all whose thoughts are fixed on you." As I fight normal everyday battles, I can not do it alone. I also can not afford to let my shadow get in the way of victory. With Christ in me, it is possible to be a pure and blameless child of God without fault in a crooked and depraved generation, in which you will shine like a star in the universe. (Phil 2:25 with a bit of paraphrasing)
Dear God, Forgive me for the times that I let fear and doubt get in the way of your light shining through me. May I not quench your spirit in any way. May I trust in you fully and keep my thoughts fixed on you alone. Thank you for your perfect peace which transcends all understanding. In Jesus name, Amen
