“A: We were all judged conditionally, “for unless you believe that I am he you will die in your sins.”
So then God either does not know the future but waits to see how things turn out or when God says “whosoever believeth in Him”, He already knows who they are and is speaking to them.
Which is it?
God knows who will or will not believe. He does not by a secret act give life to some, and give those belief. Some reject him, others accept him.
