Okay I just gave three reasons already, in response to this post.
(4) The biblical arguments provided by Open Theists cast doubt on infinite foreknowledge. They base their position on a few key verses. I've forgotten them (been 20 years since I read their material) but I do recall one example - God's testing of Abraham. There doesn't seem to be much point if God foreknew the outcome, and God Himself claims to have LEARNED something in that ordeal, "Now I know that you fear God, because you have not withheld from me your son, your only son" (Gen 22).
(5) As noted earlier, a realized infinity is a nonsense-concept.
(6) Perhaps my main argument against infinite attributes, however, is the following. Infinite attributes are by their nature innate/immutable rather than gradually acquired over time. This creates a couple of conflicts with Scripture:
(A) Innate attributes do not merit praise.
(B) An immutable God cannot become man. For example if His knowledge is innate - not acquired - it is not something that He can relinquish for the Incarnation and then reacquire later. Theologians try to solve this via the Hypostatic Union but that theory is incomprehensible (and thus counts as gibberish) in my view.
As for point #6, here are the links I promised earlier, see posts 850 and 856. Those posts summarize my entire metaphysics. They explain who Yahweh really is, why He created us, how He created us, what the Trinity is, and how He became man.
