Actually the definition of the word faith in the Greek is:
pis'-tis
From G3982; persuasion, that is, credence; moral conviction (of religious truth, or the truthfulness of God or a religious teacher), especially reliance upon Christ for salvation; abstractly constancy in such profession; by extension the system of religious (Gospel) truth itself: - assurance, belief, believe, faith, fidelity.
A primary verb; to convince (by argument, true or false); by analogy to pacify or conciliate (by other fair means); reflexively or passively to assent (to evidence or authority), to rely (by inward certainty): - agree, assure, believe, have confidence, be (wax) content, make friend, obey, persuade, trust, yield.
So I wonder who's doing the persuading, and the convincing?
