Put yourselves to a test; see if you are [really] in the faith [i.e., see if you are genuine Christians]; examine yourselves! Or, do you not realize that Jesus Christ is in your hearts, unless [of course] you fail the test [i.e., unless you are counterfeit Christians].

Do not continue to be swept off your course by all kinds of strange teachings. For it is good for your hearts to be strengthened by God's unearned favor [upon you] and not by [keeping regulations about] foods, which do not benefit those who observe them.

And the tongue is [like] a fire [i.e., like that spark]. [For] the tongue, as a part of the body, is [like] the world of evil. It corrupts the entire life [of a person] and inflames the course of nature itself [i.e., it affects a person throughout his whole earthly existence], and is ignited by hell itself [i.e., the evil produced by the fiery tongue has hell as its source and destiny].
