Wisdom, knowledge, understanding, The ways of God is unsearchable

When I applied my mind to know wisdom and to observe the activity that one does on the earth—though his eyes do not see sleep day or night— I saw every work of God, and that a man is unable to comprehend the work that is done under the sun. Despite his efforts to search it out, he cannot find its meaning; even if the wise man claims to know, he is unable to comprehend. Ecclesiastes 8:16-17

O, the depth of the riches
of the wisdom and knowledge of God!
How unsearchable His judgments,
and untraceable His ways!
“Who has known the mind of the Lord?
Or who has been His counselor?”g
“Who has first given to God,
that God should repay him?”h
For from Him and through Him and to Him are all things.
To Him be the glory forever! Amen.
Romans 11 33-36


Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly realms. For He chose us in Him before the foundation of the world to be holy and blameless in His presence. In love He predestined us for adoption as His sons through Jesus Christ, according to the good pleasure of His will, to the praise of His glorious grace, which He has freely given us in the Beloved One.

In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace, that He lavished on us with all wisdom and understanding. And He has made known to us the mystery of His will according to His good pleasure, which He purposed in Christ as a plan for the fullness of time, to bring all things in heaven and on earth together in Christ.
Eph 1:3-10

For this reason, since the day we heard about you, we have not stopped praying for you and asking God to fill you with the knowledge of His will in all spiritual wisdom and understanding, so that you may walk in a manner worthy of the Lord and may please Him in every way: bearing fruit in every good work, growing in the knowledge of God, being strengthened with all power according to His glorious might so that you may have full endurance and patience, and joyfully giving thanks to the Father, who has qualified youc to share in the inheritance of the saints in the light. He has rescued us from the dominion of darkness and brought us into the kingdom of His beloved Son, in whom we have redemption, the forgiveness of sins.
Col 1:9-14
