“If I make a model, or a cupboard, or a computer, I do not need to keep sustaining their existence, because once I have built them, they stay there unless something destroys them— they have an existence that is independent of their maker. But if I make a sound, like singing a note, the sound stops as soon as I stop making it. The sound, in fact, only exists because of its relationship with me, and has no existence of its own. The universe is like that. If God stopped sustaining it, it would have no basis to continue being there.” -Andrew Wilson, Incomparable
