It could perhaps be more helpful if we were to begin to see that all of God’s revelation to us is anthropomorphic. It is, then, essentially accomodated revelation; it is revelation accommodated to our mode of being and our mode of understanding. It is not, therefore, that God’s revelation is accommodated to us when it speaks, say, of God’s eyes or his arm or his repentance, while it is not accommodated to us when it speaks of his eternity. One quotation from Calvin may help us see the matter more clearly:
“What, therefore, does the word “repentance” mean? Surely its meaning is like that of all modes of speaking that describe God for us in human terms. For because our weakness does not attain to his exalted state, the description of him that is given to us must be accommodated to our capacity so that we may understand it. Now the mode of accommodation is for him to represent himself to us not as he is in himself, but as he seems to us. Althought he is beyond all disturbance of mind, yet he testifies that he is angry toward sinners.”
While there can be no question that there are truths given to us in God’s revelation that point to his essential character, and others that point to his covenantal character, we should be careful to note that those covenantal attributes of God’s are no less “literal” than are his essential attributes. God’s repentance, then, is not simply something that “seems to us” like repentance. It is literal repentance, he is (covenantally) changing directions because of his faithfulness to his covenant. But it is repentance of a condescended, covenant God who has come down, taking on the form of a creature, in order to glorify himself, and it is repentance that does not in any way sacrifice, undermine, or otherwise alter his essential character as a se. He repents, all the while remaining the eternal, immutable “I AM.”
