What is sin according to 1 John 3:4?
How does 1 John 3:4 define sin in a Christian context?

Text and Immediate Rendering (Berean Standard Bible)

“Everyone who practices sin practices lawlessness as well. Indeed, sin is lawlessness.” — 1 John 3:4


Legal–Covenantal Framework

The apostle equates sin with law-violation, anchoring morality in God’s own character revealed through His commands (Exodus 20; Leviticus 19:2). John writes to a mixed Jewish-Gentile audience steeped in the Old Testament concept that “where there is no law there is no transgression” (Romans 4:15), thereby confirming continuity between the Testaments.


Historical Setting and Polemic

Late first-century Asia Minor faced proto-Gnostic teachers who denied that bodily actions mattered. By defining sin as lawlessness, John dismantles that dualism and asserts objective moral norms (cf. 1 John 1:6, 2:4). Manuscript attestation—from 𝔓^9 (3rd c.) through Codex Sinaiticus—shows textual stability, undercutting claims that the church later fabricated ethical rigor.


Biblical Cross-References Clarifying “Lawlessness”

Matthew 7:23 — “I never knew you; depart from Me, you workers of lawlessness.”

Romans 6:19 — “Just as you once presented your members as slaves to impurity and to lawlessness leading to more lawlessness…”

2 Thessalonians 2:7 — “The mystery of lawlessness is already at work.”

These passages reinforce that lawlessness is a settled disposition antagonistic to God.


Theological Implications

a) Ontological Rebellion: Sin is not merely external disobedience but internal hostility (Jeremiah 17:9; Mark 7:21-23).

b) Holiness of God: Because God is holy (1 Peter 1:16), any breach of His law alienates the sinner (Isaiah 59:2).

c) Universal Guilt: “All have sinned” (Romans 3:23); hence every human stands condemned under lawlessness.


Christological Resolution

Immediately after defining sin, John states, “But you know that Christ appeared to take away sins” (1 John 3:5). The atonement—validated by the historical, bodily resurrection (1 Corinthians 15:3-8, attested by early creed dated AD 30-35)—meets the legal penalty demanded by divine justice (Isaiah 53:5-6).


Pneumatological Empowerment

Believers receive the Holy Spirit (Romans 8:9) who writes God’s law on their hearts (Jeremiah 31:33; Hebrews 8:10), enabling victory over practiced lawlessness (Galatians 5:16).


Ethical and Behavioral Outworking

• Continuous Sin vs. Occasional Stumble: The present tense highlights habitual sin; 1 John 2:1 assures advocacy for lapses but not license for patterns.

• Fruit Inspection: “Everyone who remains in Him does not keep on sinning” (1 John 3:6). Ongoing lawlessness evidences unregeneration.


Pastoral Application

a) Self-Examination: Test life patterns against God’s commands (2 Corinthians 13:5).

b) Confession and Repentance: “If we confess our sins, He is faithful…” (1 John 1:9).

c) Discipleship: Teach comprehensive obedience (Matthew 28:20), recognizing moral absolutes grounded in God’s nature, not cultural consensus.
