From Calvin’s Commentaries, Vol. 1 – Genesis, Vol. 1, pg. 64:
The invisible kingdom of Christ fills all things, and his spiritual grace is diffused through all. Yet this does not prevent us from applying our senses to the consideration of heaven and earth, that we may thence seek confirmation in the true knowledge of God. For Christ is that image in which God presents to our view, not only his heart, but also his hands and feet. I give the name of his heart to that secret love with which he embraces us in Christ: by his hands and feet I understand those works of his which are displayed before our eyes. As soon as ever we depart from Christ, there is nothing, be it ever so gross or insignificant in itself, respecting which we are not necessarily deceived.
