Faith, in the tradition from which it is drawn, was never a synonym for hope or sentiment. The Greek πίστις and the Hebrew אֱמוּנָה converge on one operational idea: reliable action based on demonstrated trustworthiness. A bridge engineer who walks across his own structure is exercising faith. A man who claims to trust the bridge but will not cross it is exercising nothing.
Faith
n. / πίστις (pistis) · אֱמוּנָה (emunah)
Not a feeling. Not optimism. Not belief without evidence. The question is not whether you trust — it is whether your trust moves you.
The verb form. An act. A movement of the will. Even the demons pisteuō — and it profits them nothing, because it never becomes action. James 2:19 is the proof.
Wind. Breath. Animating force. Not a feeling — something that rushes, departs, and moves on divine initiative. Never stored in objects. Including hair.
