"Willful Ignorance: God knows people are praying to him, but is pretending that they are not/ or he is pretending to not know that they are praying to him.
Ignoring: God knows people are praying to him, but he is choosing to not listen."
I don't really see a difference between the 'willful ignorance' as compare to the plain 'ignoring'.
As for 'all knowing'.....that's not the same as 'all aware'.
You might have the answer to every question....but to have the response for every request...is something else.
God might know the answer to all questions...however....
with 6billion people on this Earth, each one making a request, response for each one would be chaos.
Today I might pray for sunshine, as I might desire to do things outside.
Today you might pray for rain, because your crops are in need.
I might pray my death be postponed, for I have things to do.
If we all do the same...what would that do to this Earth?
It seems needful...that we die.
A request for life...will be ignored.
