Because we are, each of us, the image of God, we will worship, in fact we must worship, someone or something, either our original, as we should, or, with the illusion that we are the original or our own ultimate point of reference, ourselves. If the latter, we will give ourselves over, with the full, still efficient resources of our imaging capacities, to some figment, some distorted image, focused on ourselves or on some aspect of the world, ultimately seen as an extension of ourselves. What Calvin observed long ago is no less true today: the human heart, our image-bearing and image-fashioning nature, is an idol factory.
— Richard Gaffin from “Speech and the Image of God” in The Pattern of Sound Doctrine
