confidence: a settled state of trust or reliance, taking its whole character from whatever it rests on
This word names confidence as a settled condition rather than a passing feeling. It comes from the family of words for being persuaded and trusting, and it points to the state you are left in once you have come to trust something: you are now sure of it, and you rest your weight on it. Every one of its six appearances is in Paul's letters, and four of them fall in 2 Corinthians, where Paul is defending the trustworthiness of his own ministry.
The key to the word is that it is neutral in itself. Its worth is decided entirely by what it leans on, which is almost always spelled out by a small word like "in," "toward," or "through" that follows it. Pointed toward God and grounded in Christ, it is the quiet assurance of someone truly welcome in God's presence. Placed in a friend or a fellow worker, it is trust in a relationship. Rested on one's own achievements, it is the folly Paul mocks. The same word carries all three, sometimes within a single letter.
Paul draws a sharp line between this settled trust and self-reliance. In one breath he can claim great confidence toward God, and in the next insist that none of it comes from his own adequacy. So the word sits close to two of its neighbors: it is the inward assurance that lies behind the outward openness of παρρησία, and it is the firm resting-place that faith, πίστις, settles into once it has taken hold.
