While a critic of Open Theism, one does appreciate the intellectual honesty Randal Rauser demonstrates in his assumptions and how they colour how he exegetes and privileges certain texts over others (in this case, Isa 44:7 being the “controlling verse” of Gen 22:12 as opposed to vice versa):
But on what do I base
this assumption of divine omniscience? Like a biblicist, I could limit my case
to biblical passages which suggest that God has intimate foreknowledge of
creaturely actions (e.g. Psalm 139:16; Isaiah 44:7) and treat those as control
verses for interpreting passages like Genesis 22:12 where God is described as
learning. But that method is insufficient because it simply puts the question
back a stap: what ultimately justifies privileging passages like Isaiah 44:7 as
the interpretive control over passages like Genesis 22:12 (This point has been
effectively pressed by Open Theists)? At this point, I would argue that we can justify
a specific set of interpretive control texts by way of a prior theological intuition,
an a priori commitment to the priority of a particular concept of perfection,
a concept that includes perfect omniscience. It is because I believe God is
perfect and perfection includes comprehensive knowledge that I would prioritize
Isaiah 44:7 as a control text for Genesis 22:12. (Randal Rauser, Jesus Loves
