There’s only one way to acquire the sort of deeply affecting and stunning
emotion that is the fear of G-d, and that is by taking these bold truths to
heart, as Ramchal depicts them: first, “that G-d's Presence is found
everywhere”, and second, “that He involves Himself in everything, great and
small”. That’s to say that G-d Almighty’s will and being infuses each and
person, place, and thing at every moment, and that He interacts with
everything and everyone irrespective of their station.
In fact, “nothing is hidden from Him, either because it’s vast or
insignificant. (indeed,) regardless of whether something is great or small,
scant or imposing, G-d constantly sees and understands it” and busies
Himself with it.
After all, didn’t the prophet report that, "The whole world is full of His
Glory" (Isaiah 6:3); didn’t G-d Himself say, "Do I not fill heaven and
earth?" (Jeremiah 23:24); didn’t the psalmist effulge, "Who is like G-d our
G-d, who dwells on high, who lowers Himself to look upon the heavens and the
earth?" (Psalms 113:5-6) as well as, "Though G-d is high up, He nonetheless
notices the lowly"(Psalms 138:6)?
Given, then, that “the Holy One involves Himself in everything, and that He
sees and hears everything, you can be sure that all (your) actions make an
impression” up above, so it would be wise to always have that in mind and to
Ramchal goes on from there to then suggest that, “when it (in fact) becomes
clear to you that wherever you are, you’re standing before the Divine
Presence, you’ll (indeed) arrive at the fear and dread of stumbling in
actions that would not be fitting before G-d's profound Glory” as you’ll be
infused with the fear of Him and of sinning against Him.
