New Defender's Study Bible Notes
3:10 children of the devil. It is sobering to read that those who are not “children of God” are “children of the devil;” no middle ground is said to exist. They are also called “children of the wicked one” (Matthew 13:38), “children of disobedience” and “children of wrath” (Ephesians 2:2-3). The identification is twofold: those who do not habitually show works of righteousness, and/or those who do not habitually manifest love for other Christians. It is urgent that each one “must be born again” (John 3:3).
