For we must also say that a confirmed faith, or better, a well-grounded trust, is well worth embracing by the whole person. In fact, the word “trust,” rather than the now-privatized words “faith” or “belief,” better captures the understanding of commitment set forth in the Bible. The New Testament Greek word often translated as “believe” is more accurately rendered as “trust” (from the word pistis, “trust” or “believe,” rooted in the word peitho, “I persuade”). The biblical attitude is one of persuasion, a will to verify and know what is true and to respond accordingly.
