The book of Job, Chapter 38-42.
God flat-out tells us that we will never understand. How could we?
Indeed, we cannot say that particles or fields which have no measurable direct or indirect affects therefore do not exist. Likewise, we cannot presume to know the total number of, and types of, dimensions based on our ability to measure their direct or indirect affects.
That logic applies in our assurance that God's keeps His promises. Every. Single. One. For instance,
Thus saith the LORD, which giveth the sun for a light by day, [and] the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts [is] his name: If those ordinances depart from before me, saith the LORD, [then] the seed of Israel also shall cease from being a nation before me for ever.
Thus saith the LORD; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD. - Jer 31:33-37
We do not need a logical reason for the blessed assurance that God keeps all of His promises and yet He provides that comfort.
As another example, God is Truth. When He says a thing, it is. It is because He says it. For instance,
In the same thought, neither time nor space are properties of the Creator of them. In Scripture, the word "light" is used to describe His glory. And the metaphor is perfect as quantum mechanics confirms, i.e. the photon travels a "null path" - which is to say for the photon as observer, no time elapses at all.
Sheepherders thousands of years ago - to whom the academics love to attribute authorship for ancient Scripture - would have had no concept of quantum mechanics.
Even now, as science learns more and more, the creation itself confirms the words of the Creator, e.g. In the beginning, God created (Gen 1:1)
Truly, the most theological statement to ever come out of modern science is that there was a real beginning of space and time. (Jastrow)
God's Name is I AM.
