Most arguments against impassibility/immutability seem to be of the following form: ‘if God didn’t experience what we experience how we experience it, he wouldn’t be God at all.’ It probably isn’t meant to sound so self-refuting, though. But the core of it seems to be making how we experience what we experience the criterion for how/what God experiences – our experiences of love, pain, regret have to map on to the experience of God. To which I answer:
(1) there’s a absolute qualitative distinction between us and God – God is uncreated, we are created (2) As a result of this, God talk has to be apophatic (3) all our knowledge of experience is of created things, and God is uncreated, so we can’t really import how we experience onto how He experiences (4) going along with that, all of our knowledge of humanity and experince is also from the perspective of our fallen state, and so even moreso cant be imported to God. The overall point being, one cant simply go from our own experience and conclude that God has to share those kinds of experiences in order to live up to his name as God, because it’s importing fallen and created categories to the unfallen and uncreated God.
