How do Christians define knowledge and faith?

There have been many attempts at [defining knowledge](https://en.wikipedia.org/wiki/Definitions_of_knowledge) in philosophy. One of the most commonly used definitions is [justified true belief](https://en.wikipedia.org/wiki/Definitions_of_knowledge#Justified_true_belief) (JTB), which demands that a claim must be (1) true, (2) believed and (3) justified in order for a person to be said to *know* that claim. However, this definition has been widely challenged since the discovery of [Gettier problems](https://en.wikipedia.org/wiki/Gettier_problem) , which highlight the inherent difficulties in defining what should count as *justification*. Faith has its fair share of controversy as well as a concept: > Faith, derived from Latin fides and Old French feid, is confidence or trust in a person, thing, or concept. In the context of religion, one can define faith as "belief in God or in the doctrines or teachings of religion". **Religious people often think of faith as confidence based on a perceived degree of warrant**, **while others who are more skeptical of religion tend to think of faith as simply belief without evidence**. ([source](https://en.wikipedia.org/wiki/Faith)) **Question** How do Christians define *knowledge* and *faith*? For example, do (some) Christians claim to "know" that God exists? If so, do (these) Christians use the JTB (*justified true belief*) definition of "knowledge", and if so, what counts as "justification"? Similarly, how do Christians define *faith*? Is *faith* defined as a special kind of *belief*? If so, in what sense? And what about the relationship between *faith* and *justification*? Is faith a belief that is *justified*? Is faith a belief that is *unjustified*? If *justified*, how is it different from *knowledge*? **Related questions** - https://christianity.stackexchange.com/q/92352/50422 - https://christianity.stackexchange.com/q/91811/50422
