Since the criterion of election and pre-destination are items of interest to us, it is worth noting that the knowledge people have of God is limited. That is, God has a lot of intell going on that humans aren’t aware of, such as who really is or isn’t saved and who will or will not become saved (though they are the elect). When Jesus said; “Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand (Matthew 13:13).” it was another example of how those not yet saved do not comprehend who He is. There are a lot of people in that circumstance historically prior to salvation. God knows who eventually will be saved and not of course, yet outwardly it may be challenging to distinguish the sheep from the goats.
The statement of Jesus in John 10:26 might have been taken as an admonishment by some. His statement ‘Acts 26:14″ And when we were all fallen to the earth, I heard a voice speaking unto me, and saying in the Hebrew tongue, Saul, Saul, why persecutest thou me? it is hard for thee to kick against the pricks.” indicates that Saul had not previously heard or discerned the word well enough to withhold kicking against it. On another related point, what about this- God is unchanging because He is already perfect and all that it is possible for him to be, lacking nothing. Even so he may entail every change that might possibly be, and every item that might possibly exist, inclusive of all possible spatio-temporal Universes in their appropriate phase.
