1 John 3

The chapter moves from the theological status of the believer as a child of God to the practical, visible proofs of that status, which are defined by righteousness and love.

• When he shall appear, we shall be like him, for we shall see him as he is (1 John 3:2).
• Whatsoever we ask, we receive of him, because we keep his commandments (1 John 3:22).
• He that keepeth his commandments dwelleth in him (1 John 3:24).

• Purifieth himself (1 John 3:3).
• Love one another (1 John 3:11, 23).
• Let us not love in word, neither in tongue; but in deed and in truth (1 John 3:18).

• Marvel not, my brethren, if the world hate you (1 John 3:13).
• No murderer hath eternal life abiding in him (1 John 3:15).
• He that doeth not righteousness is not of God (1 John 3:10).

• John writes in a context where proto-Gnostic influences likely suggested that 'knowing' God was an intellectual exercise divorced from moral behavior.
• The mention of the 'world' (kósmos) reflects the tense relationship between the early Christian communities and the surrounding Greco-Roman society.

• The concept of being 'born of God' (téknon) would be starkly contrasted with the polytheistic cultural background where divine sonship was often associated with heroic myth or political power.
• The reference to 'shuttling up bowels of compassion' reflects the ancient understanding of the viscera as the seat of emotions.

• This chapter functions as a central section in 1 John, bridging the discussion of the Antichrist (ch. 2) and the practical demonstration of Christian love.
• The structure is chiastic in thought: identity (1-3), nature of sin (4-10), nature of love (11-18), confidence (19-24).

• The reference to Cain (v. 12) directly alludes to the narrative in Genesis 4:1-16, characterizing Cain's action as the first instance of 'lawlessness' and 'hatred' toward the righteous.
• The command to 'love one another' draws upon the 'new commandment' given by Jesus in the Upper Room (John 13:34).

• 1 John 3:12 references Genesis 4:4-8, specifically the contrast between the works of Cain (evil) and his brother Abel (righteous).
• 1 John 3:23 echoes the commandment in John 13:34 and John 15:12, linking faith in the Son to the mandate of love.

• potapós [G4217]: 'What manner'—expresses amazement at the quality or nature of the love, indicating it is alien to the present world.
• anomía [G458]: 'Lawlessness'—John defines sin strictly as the violation of God's revealed standard, countering any view that sin is merely a temporary lapse.
• hagnízō [G48]: 'Purifieth'—refers to a continuous, active process of moral cleansing in the life of the believer, not a one-time judicial act.
• Matthew Henry observes regarding verse 9 ('cannot sin'), that the 'new nature' or 'seed' of God makes the habitual, unrepentant practice of sin contrary to the believer's new identity; it is not a claim of absolute perfection, but of a transformed nature that hates sin.

• The distinction between voluntary observation and earnest inspection in the Greek terms for 'see' (eídō vs. optánomai), highlighting that the believer's future state involves more than casual observation of Christ.
• The present tense verbs throughout the section on sin (e.g., 'sinneth not') imply a habitual, ongoing lifestyle rather than a single act.

• The interpretation of 'cannot sin' in 1 John 3:9. Historic views include: 1) The 'perfectionist' view (Wesleyan), claiming complete victory over known sin; 2) The 'habitual' view (Reformed/General), interpreting the Greek present tense to mean 'does not practice/continue in sin'; 3) The 'positional' view, arguing that the 'seed' (the new man) is incapable of sinning, even while the flesh is still present. The text itself emphasizes the incompatibility of sin with the 'seed' of God.
