Let us not forget that the greatest composers were also the greatest thieves. They stole from everyone and everywhere.
Writers do much the same thing, though I do not believe it is proper to call it theft. We learn something from everything we read and everything we see. Often it is just a little impression that adds a small detail to our understanding of the things happening around us. Occasionally it is a profound thought that jars us out of the rut are thoughts have settled into.
These are the inputs into our mental processes. They all get jumbled up, then sorted out, and the output is our attempt to send out, via our writing, a glimmer of light to help someone else see something they might otherwise have missed.
Romans 12:2 warns us not to let our thinking be shaped by the zeitgeist, the prevailing attitudes in the world around us in the era in which we live. The danger for us, for me, is that I would tend to interpret that as meaning I need to remain entrenched in the zeitgeist that prevailed several generations ago when I was growing up. But the verse goes on to say that I need to be transformed by the renewing of my mind to prove the will of God for me, here and now in the era in which I am living.
The world is a place of dancing shadows. As I read, listen and observe, I become aware that everyone has a longing for truth and light. Many grasp a shadow and call it light, then are devastated when that shadow dissolves or changes shape. Those who do not give up too soon are still finding true light. Reading, listening, observing helps me understand why other people are looking for light in places where there is no light.
As a Christian, I believe the Bible and the Holy Spirit are sources of light that reveal things as they truly are. Yet, if I see, then withdraw into the wilderness I am shirking my responsibility to point others to the place where light is to be found.
