These people claim to know God [as Savior], but they deny Him by their actions, so they are detestable and disobedient and unfit for doing anything good.

You should teach these things and exhort and rebuke people with full authority. Do not let anyone look down on you. [See note on I Tim. 4:12].

This saying is trustworthy and I want you [in your teaching] to affirm these things with confidence, so that those people who have trusted God will be careful to devote themselves to doing good deeds. These things [i.e., just mentioned] are good and profitable for people [to do].
