Have you not known? have you not heard, the everlasting God, the LORD, the Creator of the ends of the earth, faints not, neither is weary? there is no searching of his understanding. (Isaiah 40:28)
Mankind is made in God's image, but the similarity ends there. He is infinite in every possible way while we are finite. He is Spirit. We are flesh and blood. He is the beginning and the end of all things. We came from nothing and we return to nothing.
"HIS UNDERSTANDING IS INFINITE." (Psalms 147.1/5) How deep is infinite? It is endlessly deep. How wide is infinity? It is endlessly wide. How high is the infinite? It is endlessly high. Infinity has no boundaries. There is no end to God's understanding. He understands all things in their relationship to the totality of all reality past, present and future in his Universe from their beginnings to their ends whereas humanity is usually stuck in the finiteness their five senses provide.
All of the incredible knowledge stored up in the computers of the world is nothing to God. It represents what man has been able to gather corporately from the finite understanding of millions of individuals. What is in mankind's computers is localized primarily to the last hundred years, then it diminishes as man attempts to gather information further into the past; and I think you already know there are very few humans who know anything about the future, so our computers are blind in many ways.
There is no searching out God's understanding. (Isaiah 40:28) Mankind tries to search out things God has created, going deep into the oceans to see what God has done while sending missions deep into outer space to photograph what they can of the Universe God created, yet with such ignorance they deny His existence while doing it.
Mankind wants to know the truth without knowing the essence of all Truth in God Almighty, so the search goes on without any hope of success except for those who seek His Face.
God is the Light of the world. Any understanding in a man is provided by God.
It is the inspiration of the Almighty that gives a person understanding. (Job 32:8)
Darkness is like the noon day sunlight to God. He sees in darkness just the same as he sees in the daylight. (Psalm 139:11)
God sees all of mankinds goings with infinite understanding and the power to make it all happen. (Job 34:21) (Psalm 33:13)
The Prophet in Psalms writes: "OH LORD, HOW GREAT ARE YOUR WORKS! AND YOUR THOUGHTS ARE VERY DEEP." (Psalm 92:5) God knows everything. (1 John 3:20) He knows everything taking place in the universe in the moment we are in. He knows your every thought before you think it. He knows the beginning and end of your life before you live it. He knows the past, present and future of all mankind individually and historically.
Here is God's advice to mankind: "LET NOT THE WISE MAN GLORY IN
HIS WISDOM, NEITHER LET THE MIGHTY MAN GLORY IN HIS MIGHT,
LET NOT THE RICH MAN GLORY IN HIS RICHES: BUT LET
HIM THAT GLORIES GLORY IN THIS, THAT HE UNDERSTANDS
AND KNOWS ME, THAT I AM THE LORD WHICH EXERCISES
LOVING KINDNESS, JUDGMENT, AND RIGHTEOUSNESS, IN
THE EARTH: FOR IN THESE THINGS I DELIGHT," SAITH
THE LORD. (Jeremiah 9:23/24)
