I've been reading John Frame's The Doctrine of the Knowledge of God, which I'm enjoying very much. I had one bit fairly early on I was particularly struck by and wanted to excerpt here. Frame is discussing how God's thoughts are different from ours:
2. God's thoughts ultimately determine, or decree, what comes to pass. God's thoughts cause the truths they contemplate; ours do not. This is the Lordship attribute of control in the realm of knowledge.
3. God's thoughts, therefore, are self-validating; they serve as their own criteria of truth. God's thoughts are true simply because they are his. None of us can claim to have such self-attesting thoughts. Our thoughts are not necessarily true, and when they are true, it is because they agree with the thoughts of someone else, namely God, who furnishes the criteria for our thinking...
8. God possesses knowledge in a different way from us. He is immaterial and therefore does not gain knowledge from organs or perception. Nor does he carry on "processes of reasoning," as understood as temporal sets of actions.
I don't have a lot to add to what he said, but I found point 8 very striking. It's easy to anthropomorphize God and start thinking that he must be reasoning about things, responding to my decisions, etc. While God does act in time, he is eternal and omniscient, and, as Frame points out, doesn't carry out processes of reasoning like I do. When I start thinking of God in anthropomorphic terms, I reduce him in my thoughts to less than he really is.
