"And I was with you in weakness and in much fear and trembling; and my speech and my message were not in plausible words of wisdom, but in demonstration of the Spirit and of power, that your faith might not rest in the wisdom of men but in the power of God" (1 Corinthians 2:3-5 RSV).
It's hard to take this verse out of the context of verses 3 and 5. Paul is writing from Ephesus to the church he founded in Corinth. It would seem that another leader has visited them with a message different from Paul's—more logical, more intellectual. Paul's passionate reminder is that he did not speak from "the wisdom of men." His speech and message came directly from the guidance of Spirit. Paul himself was often weak and fearful, but the Spirit he shared was clear and direct. He goes on to amplify the idea that his message is not grounded in the wisdom of men, but rather "a secret and hidden wisdom of God" (v. 7) that will not make sense to the entire world, but only to "the mature" who are ready to receive its Truth.
Today we sometimes try to justify our understanding of spiritual Truth by turning to the human knowing of mortal mind. We may rely on our guidance in making life choices, but then try to defend those choices—which are not always "logical" from the perspective of mortal mind—by trying to explain them in ways that will make sense to others. That's fine, but it requires a lot of energy that could be better used in other ways. Spiritual guidance is what it is. It doesn't come from mortal mind, but from our Christ Self. Our oneness with Source is the "secret and hidden wisdom" that allows us to trust without question, and without feeling defensive, the guidance that flows from that Self.
