A great many skeptics have defined “faith” as “a belief that is ​not ​based on evidence,” and for some reason, many evangelicals accept this definition. But is this the way “faith” is used in the New Testament when Paul, Peter, or Jesus use it? Is this definition accurate in relation to the way the word was used in other works of ancient Greco-Roman literature? How do writers like Aristotle, Herodotus, Diodorus, and others who wrote in Koine Greek use the same word? Do they use it to mean “belief without evidence”? Or do they mean something entirely different. In this article we will explore these questions and clarify what is really meant by “faith.”
