3:8-9 He that
committeth sin is of the devil; for the devil sinneth from the beginning. For
this purpose the Son of God was manifested, that he might destroy the works of
the devil. Whosoever is born of God doth not commit sin; for his seed remaineth
in him: and he cannot sin, because he is born of God.
This passage continues the line of thinking John
established in the previous two verses: the contrast between habitual sinning
and habitual abstinence from sin. Those who confess Christ but have no issue
with continuing in a lifestyle of flagrant, habitual sin are of the devil, John
writes. Jude agrees: “These (false confessors) are grumblers, complainers,
walking according to their own lusts; and they mouth great swelling words,
flattering people to gain advantage,” Jude 1:16.
