S&H 23:21 In Hebrew, Greek, Latin, and English, faith and the words corresponding thereto have these two definitions, trustfulness and trustworthiness. One kind of faith trusts one's welfare to others. Another kind of faith understands divine Love and how to work out one's "own salvation, with fear and trembling." "Lord, I believe; help thou mine unbelief!" expresses the helplessness of a blind faith; whereas the injunction, "Believe . . . and thou shalt be saved!" demands self-reliant trustworthiness, which includes spiritual understanding and confides all to God.

S&H 488:7 The Hebrew and Greek words often translated belief differ somewhat in meaning from that conveyed by the English verb believe; they have more the significance of faith, understanding, trust, constancy, firmness. Hence the Scriptures often appear in our common version to approve and endorse belief, when they mean to enforce the necessity of understanding.
