God is relation, full stop. He is like reality in this regard. Consider an electron, the fundamental unit of all matter. No one has ever seen one. They really don't "exist" until we turn our attention to them. The physicist Marcelo Gleiser says that "exist" may be too strong a word to use for an electron. I take God's existence to be much the same, though for God "exist" is too weak a word. We don't know what the existence of God is. We have no idea what the word "exist" even means in the context of God. What we do know—or what I know, I should say—is that God doesn't exist until I turn my attention to him. Relation brings him into being, or, more accurately, enables his being to be perceived, experienced, shared. My attention—and the precise quality of that attention—is absolutely involved. I realize this is unorthodox at best, heretical at worst. But it is my experience of being in the world and of being with God. "The feeling remains," as Teresa of Avila says, "that God is on the journey, too."
