33 Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out!
“How” is a term of exclamation.
unsearchable [unfathomable] are His judgments [determinations]
“Unsearchable” demonstrates that human beings cannot exhaust their search about why God does what He does. God’s judgments are not capable of being fully investigated. Decrees are not sortable for a finite being. If God had not revealed some of His “judgments” in the Word and creation then we would even be further afield. The word “unsearchable” show how impossible it is to trace the means God used to put His decisions into place.
God’s “judgments” here pertain to His purpose or plan for creation. A judgment is the ability to make a right decision about something. His understanding is such that His decisions to formulate a plan for creation have been perfect.
In the Old Testament the term is used in the book of Job:
Job 5:9, Who does great things, and unsearchable, Marvelous things without number.
Job 9:10, He does great things past finding out, Yes, wonders without number.
“Judgments” probably refers to God’s decree or purpose. This involves His eternal decision to create and how He put it into effect. It also involves all of His decisions that have ever existed.
Ps 119:75, I know, O Lord, that Your judgments are right, And that in faithfulness You have afflicted me.
We must accept our limitations when it comes to understand an absolute, infinite God.
Since God is absolute He does not do things in succession. He is not progressive in His knowledge. He does not do things in a temporal sense (sequentially). His judgments about the universe occurred with one fell swoop. If God had to learn things in sequence then He would not be perfect but limited in some sense.
