Where are all the treasures of wisdom and knowledge hidden?
All the treasures of wisdom and knowledge are hidden in God, specifically in the mystery of God the Father and of Christ, in whom they are hid. The context emphasizes that this treasure and knowledge is hidden in God Himself.
Les explains that this truth is part of the mystery Paul brings out. The context asks, 'All treasure and knowledge is hid where?' and answers, 'In God.' This hiding is connected to the mystery of God the Father and of Christ. Les notes that the Old Testament is vague about the Trinity, and that the revelation of the triune God—Father, Son, and Holy Spirit—is part of the mystery. The Hebrews and rabbis do not recognize the Trinity, but Paul reveals it. So all treasures of wisdom and knowledge are hidden in the triune God, not in human philosophy.
