If He's Unchanging

If He's unchanging, that means He's with me today. Even if the waiting continues. Even if the answer continues to be "hold on". Or in eternity, does unchanging mean exhaustible? Does it mean that if we're there long enough, we can get to the bottom of everything? Or perhaps it means His depths are truly incomprehensible. That, actually, He's apart from infinity. If I can conceive of infinity when I am finite, what of the mind that conceived the mind that can conceive infinity? Have pity for I have uttered what I did not understand.
