There is a common experience among artists one I have recently come up against. I defer to John Paul the Great's expression of this experience in his Letter to Artists.
"A fruitful alliance between the Gospel and art
6. Every genuine artistic intuition goes beyond what the senses perceive and, reaching beneath reality's surface, strives to interpret its hidden mystery. The intuition itself springs from the depths of the human soul, where the desire to give meaning to one's own life is joined by the fleeting vision of beauty and of the mysterious unity of things. All artists experience the unbridgeable gap which lies between the work of their hands, however successful it may be, and the dazzling perfection of the beauty glimpsed in the ardour of the creative moment: what they manage to express in their painting, their sculpting, their creating is no more than a glimmer of the splendour which flared for a moment before the eyes of their spirit.
Believers find nothing strange in this: they know that they have had a momentary glimpse of the abyss of light which has its original wellspring in God. Is it in any way surprising that this leaves the spirit overwhelmed as it were, so that it can only stammer in reply? True artists above all are ready to acknowledge their limits and to make their own the words of the Apostle Paul, according to whom "God does not dwell in shrines made by human hands" so that "we ought not to think that the Deity is like gold or silver or stone, a representation by human art and imagination" (Acts 17:24, 29). If the intimate reality of things is always "beyond" the powers of human perception, how much more so is God in the depths of his unfathomable mystery!"
How many of us have this experience: there is something burning in you and you want to create an image to capture that fleeting moment. Such a human moment! As Cardinal Stafford said once in an essay on artists that we are windows through which God's glory can shine through to the world which hungers for the vision of the infinite, the Lord.
