1 John 2:3
3 And hereby we do know that we know him, if we keep his commandments.
Chapter Context
1 John 2 is a theological epistle chapter in the New Testament that explores themes of truth, love, holiness. Written during the late first century CE (c. 85-95 CE), this chapter should be understood within its historical context: Early Gnostic ideas threatened the understanding of Christ's incarnation and redemption.
The chapter can be divided into several sections:
- Verses 1-5: Introduction and setting the context
- Verses 6-12: Development of key themes
- Verses 13-20: Central message and teachings
- Verses 21-29: Conclusion and application
This chapter is significant because it addresses timeless questions about faith, suffering, and divine purpose. When studying this passage, it's important to consider both its immediate context within 1 John and its broader place in the scriptural canon.

1 John 2:3
3 And hereby we do know that we know him, if we keep his commandments.
Analysis
And hereby we do know that we know him, if we keep his commandments. John introduces the first of several tests of genuine saving knowledge. "Hereby we do know" (en toutō ginōskomen, ἐν τούτῳ γινώσκομεν) provides assurance based on evidence, not feelings. The verb "know" (ginōskō) indicates experiential, relational knowledge—not mere intellectual awareness but intimate acquaintance with God. The test is simple: "if we keep his commandments" (ean tas entolas autou tērōmen).
"Keep" (tēreō, τηρέω) means to guard, observe, and obey carefully—implying devoted attention and protective custody of God's word. The present subjunctive "keep" indicates habitual, ongoing obedience as lifestyle, not sinless perfection or occasional compliance. This isn't legalism (earning salvation by rule-keeping) but evidence of regeneration. Those who genuinely know God demonstrate that knowledge by obeying His revealed will.
The phrase "know that we know him" emphasizes assurance. Believers can have confidence they truly know God—not based on mystical experiences or emotional states but on objective evidence: transformed lives marked by obedience. This test refutes Gnostic claims of superior knowledge divorced from ethics. True knowledge of God necessarily produces holy living. Those who claim to know God while habitually disobeying His commands deceive themselves—their profession is false.
Historical Context
In the Greco-Roman world, religious knowledge was often separated from ethical behavior. Greek philosophy pursued truth through reason; mystery religions offered ecstatic experiences. Neither necessarily demanded moral transformation. Gnostic teachers explicitly divorced spiritual knowledge from bodily conduct, arguing that enlightened souls weren't affected by physical actions.
John's emphasis on commandment-keeping would resonate with Jewish Christians familiar with covenant obedience. Deuteronomy 6:1-9 commands love for God expressed through keeping His statutes. Yet John transcends mere external compliance—he speaks of new covenant obedience empowered by the indwelling Spirit (1 John 3:24). This is heart transformation, not mechanical rule-following.
The early church faced antinomian threats repeatedly. Some distorted Paul's gospel of grace into license to sin (Romans 6:1). Others, like the later Marcionites, rejected the Old Testament's moral law. John's test provided crucial balance: salvation is by grace through faith alone, yet genuine faith necessarily produces obedience. James would make the same point: faith without works is dead (James 2:17, 26).
Reflection
- How can you distinguish between legalistic commandment-keeping (to earn favor) and evidence-based obedience (proving regeneration)?
- What specific areas of your life reveal whether you truly know God through obedience or merely know about Him intellectually?
- How does this verse guard against both presumption (claiming salvation without transformation) and despair (demanding perfect obedience for assurance)?
