Anything that knows everything also knows how it knows everything, and how it knows that, etc. ad infinitum. Infinite protraction is impossible; therefore omniscience is impossible.
There are those who will say it's possible, But then what do they know, When they are only told by someone else it's possible to know everything.
But then there's nothing in the Bible that says God is all knowing.
The closest the bible does come is in the book of Revelation 19:6, But then this only says God is Omnipotent, Which only means that God is all powerful.
But nothing about God as being all knowing as alot people are taught, Which is nothing more than a false teaching of man's.
You will find in the book of Matthew 28:18, Where Jesus said--"All power is given unto me in heaven and in earth"
But nothing about as being all knowing.
So where do people get this from, No other place but from their pastors, and then their off running with what ever their pastors tell them and then they go about telling other people that God is all knowing, Unto which they themselves do not even know if God is all knowing only what their Pastor's have told them. Without even checking it out if the Bible even supports such a teaching.
But then people will go about trying to twist the bible into what they would like it to say, just to support their agenda.
But upon searching it out, the bible makes no such claim, as they would like the Bible to do.
That's like people with their Rapture Theory, When in fact there's no place in the Bible to support this claim either.
Their Rapture can not happen until the last Prophecy of the book of Revelation happens first, But then by the time the last Prophecy of Revelation happens, the Tribulation is over,
So what good is the Rapture going to do.
The whole point of their Rapture Theory, is to Rapture people out before the Tribulation and not after the Tribulation is over.
But anyway, just like their Rapture Theory, there is no where in the Bible that supports God as being all knowing, As they could only wish the bible did.
Oh they'll try to pick out a verse here and there and try to imply that it means God is all knowing. But upon closely examination of the said verse, it doesn't say at all,
that God as being all knowing.
