Here's an image, a "visible" of human participation in the Divine, of cooperation, of union. But there is more than we can see in this image, there is the reality it points us towards, the "invisible".
"The icon summons the gaze to surpass itself by never freezing on a visible, since the visible only presents itself here in view of the invisible. The gaze can never rest or settle if it looks it on an icon; it always must rebound upon the invisible, in order to go back in it up the infinite stream of the invisible. In this sense, the icon makes visible only by giving rise to an infinite gaze." Jean-Luc Marion, "God Without Being"
