1 John 1:10
10 If we say that we have not sinned, we make him a liar, and his word is not in us.
Chapter Context
1 John 1 is a theological epistle chapter in the New Testament that explores themes of redemption, truth, prayer. 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 6-10: Development of key themes
This chapter is significant because it demonstrates God's faithfulness despite human unfaithfulness. When studying this passage, it's important to consider both its immediate context within 1 John and its broader place in the scriptural canon.

Analysis
If we say that we have not sinned, we make him a liar, and his word is not in us. John concludes the chapter with the most serious form of denial: claiming we have not sinned at all. This differs from verse 8 (denying we have sin/sin nature); this denies any sinful acts. The present perfect tense "have not sinned" (ouch hēmartēkamen, οὐχ ἡμαρτήκαμεν) suggests denying a history of sin with continuing effects.
The consequence is severe: we "make him a liar" (pseustēn poioumen auton, ψεύστην ποιοῦμεν αὐτόν). God's Word declares that all have sinned (Romans 3:23). To deny our sin is to contradict God, calling Him a liar. This is cosmic arrogance—setting our self-assessment above God's declaration. It reverses the serpent's temptation: the serpent called God a liar; claiming sinlessness does the same.
"His word is not in us" indicates more than intellectual rejection—it means the living Word (Christ) and the revealed Word (Scripture) have not taken root in our hearts. Genuine encounter with God's holiness and truth produces conviction of sin (Isaiah 6:5, Luke 5:8). Those who claim sinlessness reveal they haven't truly met the God who is light. This sobering warning concludes the chapter's tests: walking in fellowship with God requires walking in light, confessing sin, and receiving ongoing cleansing—never claiming we've arrived at sinlessness.
Historical Context
Some Gnostic teachers claimed they'd transcended sin through their enlightenment. Others redefined sin so that their behavior didn't qualify. Some argued that actions performed by the body didn't constitute sin for the enlightened spirit. All these positions effectively called God a liar by contradicting His revealed truth about human sinfulness.
The early church faced this challenge repeatedly. Pelagius denied original sin and claimed humans could achieve sinlessness through willpower. Augustine refuted this, establishing Christian orthodoxy: all humans inherit sin from Adam, all commit actual sins, and none achieve sinlessness in this life except Christ. The Council of Carthage (418 AD) condemned Pelagianism as heresy.
Throughout history, perfectionist movements have claimed achievable sinlessness, from some medieval mystics to certain Pentecostal and Holiness groups. Reformed theology consistently maintains that believers remain simultaneously justified and sinful (simul justus et peccator) until glorification.
Reflection
- In what ways might you be minimizing your sin or comparing yourself favorably to others rather than to God's standard?
- How does growth in sanctification reveal previously unseen sin rather than leading to claims of greater righteousness?
- What would it look like practically to acknowledge that claiming sinlessness makes God a liar?
