Observation: The apostle Paul continues his explanation of the power of God rooted in the Spirit of God. God's wisdom cannot be found in human wisdom. God is a mystery to be explored.
Application: As humans we want definitive answers. Yet God is not expressed in definiatives but through mystery. When I was in deep kairos around the age of 22, I remember talking to my mother (the best theologian I know) about the deep divide I felt within my life; a divide between faith and reason, head and heart. After exploring this pain with her for 45 minutes sobbing through it. My mother in great compassion looked at me and said "Son, sit back and enjoy the mystery." Those words still rattle my philosophic desire to know God more closely but it serves me to know more God intimately not through rational.
Kallistos Ware, an Eastern Orthodox Bishop said it well - "It is not the task of Christianity to provide easy answers to every question, but to make us progressively aware of a mystery. God is not so much the object of our knowledge as the cause of our wonder.
