Truly, mortal men are traveling worldlines "in" space and time. As such all mortal men suffer from the observer problem - only God can see "all that there is" all at once. Objective truth is knowable only to Him and can only be received by His revelation.
To God be the glory!
Cheers!
...oh, and Merry Christmas!
It seems to me God is the only objective observer there can be, for the very simple reason that He is not caught up in the net of space and time of the Creation He made; He is not Himself contingent on anything beyond Himself; that is, He is utterly, timelessly self-subsistent (i.e., uncaused) Being. He stands outside of the creation He made, and thus is the only one who can see it all "entire," from Alpha to Omega, all at once — past, present, and future — and also in terms of the purpose of His creating in the first place (i.e., "in the beginning").
How much knowledge do we human beings really think we have, when we get only partial views of reality, and those filtered through five narrow lenses of sensory perception? What can we actually say we know about something whose past is obscured to us, and whose future is yet to be actualized?
Man can't do that sort of thing!
But God can. And does. And He reaches out to us to clue us in....
To God be the glory!
