"… Scripture necessarily speaks of God in anthropomorphic language. Yet, however anthropomorphic its language, it at the same time prohibits us from positing any change in God himself. There is change around, about, and outside of him, and there is change in people’s relations to him, but there is no change in God himself. In fact, God’s incomprehensible greatness and, by implication, the glory of the Christian confession are precisely that God, though immutable in himself, can call mutable creatures into being. Though eternal in himself, God can nevertheless enter into time and, though immeasurable in himself, he can fill every cubic inch of space with his presence. In other words, though he himself is absolute being, God can give to transient beings a distinct existence of their own. In God’s eternity there exists not a moment of time; in his immensity there is not a speck of space; the creature, eternity which posits time, immensity which posits space, being which posits becoming, immutability which posits change. There is nothing intermediate between these two classes of categories: a deep chasm separates God’s being from that of all creatures. It is a mark of God’s greatness that he can condescend to the level of his creatures and that, though transcendent, he can dwell immanently in all created beings. Without losing himself, God can give himself, and while absolutely maintaining his immutability, he can enter into an infinite number of relations to his creatures.

…(God), the immutable One, is himself the sole cause of all that changes. We should not picture God as putting himself in any relation to any creature of his as though it could even in any way exist without him. Rather, he himself puts all things in those relations to himself, which he eternally and immutably wills - precisely in the way in which and at the time at which these relations occur. There is absolutely no “before” or “after” in God; these words apply only to things that did not exist before, but do exist afterward. It is God’s immutable being itself that calls into being and onto the stage before him the mutable beings who possess an order and law that is uniquely their own."
