2 cor. 12.
God shows perfect power in weakness. Being secure in weakness means that i show my weakness. By showing my weakness I am demonstrating that anything in me that is powerful or good is not from me, since I am constantly displaying my weakness. By showing our weakness we are showing christs strength. By showing we are incapable, we show christ’s strength.

Ecclesiastes basically bashes life and concludes life is meaningless without God. That means everything in life is meaningless without god. Everything is meaningless without god in everything. Relationships, friendships, jobs, money, all meaningless without God in the center of it.
