God does not like to hear certain things. the Holy Spirit does not dwell with the wicked but with the righteous. now since God is three personas, explain to me why he can't both know all things and know some things and not know other things?
that is what I said and I would very much say that the Holy Spirit does not know evil. this would mean that all the language of the bible that seem like crude human things really have a deeper and far more innocent spirit in them.
so yeah I could say that God is not ignorant in some sense. but remember that "with God all things are possible"
the Holy Spirit is the tree of life, not the tree of knowledge of good and evil.
Luke 13:23-28 (YLT)
and a certain one said to him, `Sir, are those saved few?' and he said unto them, `Be striving to go in through the straight gate, because many, I say to you, will seek to go in, and shall not be able; from the time the master of the house may have risen up, and may have shut the door, and ye may begin without to stand, and to knock at the door, saying, Lord, lord, open to us, and he answering shall say to you, I have not known you whence ye are, then ye may begin to say, We did eat before thee, and did drink, and in our broad places thou didst teach; and he shall say, I say to you, I have not known you whence ye are; depart from me, all ye workers of the unrighteousness. `There shall be there the weeping and the gnashing of the teeth, when ye may see Abraham, and Isaac, and Jacob, and all the prophets, in the reign of God, and yourselves being cast out without;
obviously if someone could understand the underlying spiritual reality of this parable they would be forced to change their views and understanding about God and how he judges people, what hell is, what the kingdom of God is, ectect.
