New Defender's Study Bible Notes
3:3 Without natural affection. The implication is that their “affections” are “unnatural.” Note Romans 1:26-27. Evidently a great and dangerous increase of perverse sexual behavior will characterize the last days.
3:3 trucebreakers. Translated “implacable” in Romans 1:31. The etymology of the word suggests people who refuse to make or honor treaties or agreements.
3:3 false accusers. The Greek for “false accusers” is diabolos, meaning “slanderers” or “devils.” Satan himself is the diabolos, the devil, the false “accuser of our brethren” (Revelation 12:10), and there are today a multitude of people slandering Bible-believing Christians, doing the specific work of the devil.
3:3 incontinent. The Greek for “incontinent” (akrates) means “without strength,” meaning, in context, powerless to do what is known to be right.
