I find this to be an interesting discussion....While, I am decidedly of the opinion that God never "learns" anything, and therefore take the position that his Omniscience is indeed exhaustive...I do not find the position of those who disagree to be mere "heresy" etc...Consider: Christ himself indeed "emptied" himself of some of his Divine attributes (at least in certain circumstances, and only at will). This is not to say that he didn't Posses them....nor is it to say that he COULD not have taken them back up at any point...He did indeed raise himself by his own power no? That being said...he did not in fact, "know" when his return would be....only the Father knew that.
Mat 24:35 Heaven and earth shall pass away, but my words shall not pass away.
Mat 24:36 ¶ But of that day and hour knoweth no [man], no, not the angels of heaven, but my Father only.
This tells me, (as do other Scriptures) that God is at least capable of placing certain limits upon himself in certain circumstances and only at will.
It would be nice if those who maintain exhaustive Omniscience as I do, would at least entertain some of the ideas presented by our noble opposition and learn from them.
I suppose that the better way to view it is this...it is not as though suggesting that God can "learn" should necessarilly be relegated to some imputation upon his Omnipotence...but rather, at least, the possibility that he is indeed capable of imposing his own limits at will. I do not specifically argue that he does, but that it is at least not impossible. Similarly...there are those who feel that to exhaustivley foreknow all outcomes of creaturely volition or "choices" is to render them "determined" or not, in fact, "real" choices...I believe a lot of O.T's think this way...I patently disagree with them about that....inasmuch as I maintain that all choices can be known and also not determined. I do not think that makes them "heretics" though.
While we hold differing views, this post is spot on. That God knows what He has chosen to know, rather than everything imaginable is fully consistent with all scripture. The name calling folks deny the obvious.
It is important to believe what scripture actually says, rather than the doctrines of men which do not fit with all scripture, in order to say we believe in the God of the Bible, rather than the god of man's invention.
