The Incompatibility of a Lifestyle of Sin and the New Life in the Savior
Main Idea of 1 John (The Central Thesis):
1 John is a pastoral letter written to provide believers with absolute assurance of their salvation and fellowship with God. It serves as a definitive guide to distinguishing truth from error by applying the “tests” of sound doctrine, righteous living, and sacrificial love, all rooted in the historical reality of Jesus Christ.
The Logical Bridge (The Contextual Link):
In the previous lesson (3:1–3), John focused on the staggering basis of our sonship: the Father’s extravagant love, which motivates us to purify ourselves as Christ is pure. Now, in 1 John 3:4–6, John moves from the motivation for holiness to the nature of sin itself. He provides a stark, absolute contrast between the nature of sin and the nature of Christ. By defining sin as “lawlessness” and reminding us of Christ’s mission to “take away sins,” John demonstrates that a life characterized by habitual sin is fundamentally incompatible with a true relationship with the Savior.
The Text: Sin is Lawlessness:
“Everyone who commits sin practices lawlessness; and sin is lawlessness. You know that he was revealed so that he might take away sins, and there is no sin in him. Everyone who remains in him does not sin; everyone who sins has not seen him or known him.”
— 1 John 3:4–6 (CSB)
Observations (What the Text Says)
The Identity of Sin (v. 4): John explicitly equates committing sin with the practice of “lawlessness”.
The Divine Purpose (v. 5a): Christ was “revealed” (appeared) for a specific judicial and redemptive purpose: to take away sins.
The Character of Christ (v. 5b): John affirms the absolute sinlessness of Jesus: “there is no sin in him”.
The Result of Abiding (v. 6a): Remaining (abiding) in Christ results in a life that “does not sin”.
The Mark of Falsehood (v. 6b): Continuing in a lifestyle of sin is evidence that a person has neither seen nor truly known Christ.
Interpretation: Lawlessness vs. The Lamb (Understanding the Meaning)
The Nature of Sin as Rebellion (v. 4)
“Sin is Lawlessness”: Sin is a fundamental rejection of God’s authority. It is a state of living as if there were no law—placing oneself as the final authority instead of God.
“Practices Lawlessness”: This indicates a lifestyle or a direction of thinking that contradicts the clear Word of God.
The Honest Reality of the Believer (The 1:8 Balance)
John is not teaching that believers reach a state of sinless perfection in this world. In fact, he previously stated, “If we say we have no sin, we deceive ourselves, and the truth is not in us” (1:8). So what do we make of this?
Capable of Sin: True believers are still capable of sinning and do so in many ways—whether in mind, speech, action, or the failure to do what is right. But we are often guilty of focusing on the “speck of dust” in the eyes of others while ignoring the “log” in our own. We must honestly examine ourselves, not just against the outward “crimes” or “big sins” of others in society, but in light of a general lack of love for the Lord in our own hearts—the root cause that produces all sin.
The Habitual Distinction: There is a massive difference between a believer who stumbles into sin—or is temporarily caught up in it—and someone who “practices lawlessness” as a continuous lifestyle. When we think of sin, we often jump to “major” things like sexual immorality or murder; however, we must pause and consider our very own “smaller” or what Jerry Bridges calls “respectable sins” too. These are often rooted in a lack of love for God and a failure to do what we know is right (James 4:17):
Ungodliness: Living daily life with little or no thought of God, or without reference to Him (lip service, but practical atheism).
Anxiety and Frustration: A failure to trust in God’s sovereignty and a subtle form of rebellion against His providence.
Discontentment: An inability to be satisfied with one’s current circumstances.
Unthankfulness: Failing to maintain a grateful heart toward God in all circumstances.
Pride and Judgmentalism: A judgmental spirit toward the sins of others while overlooking our own “subtle” transgressions.
Gossip and Slander/Reviling: Often masked as “prayer requests” or concern, but recognized as a highly destructive sin.
Anger, Irritability, and Bitterness: Frequently directed at those closest to us.
Worldliness: Being overly attached to or preoccupied with the things of this temporal life.
Selfishness and Lack of Self-Control: Even in how we manage our time.
The Necessity of Repentance: A lack of love for the Lord is the engine behind every one of these behaviors. While it is possible that a believer may fall into these, they cannot live in a state of continuous, habitual practice of them without eventually being brought to real, heart-felt repentance by the Holy Spirit.
As the “Definition of Sin” (1 John 3:4) reminds us, sin is lawlessness—a rejection of God’s rule. To persist in a lifestyle of sin, even these “respectable” sins without eventual growth and change in conviction would be to prove that one has never truly known Christ (1 John 3:6).
The Mission of the Sinless Savior (v. 5)
“To Take Away Sins”: Christ came not only to forgive us of our sins but to save us from them. He was revealed to destroy the works of the enemy and the power of sin in our lives. We must continually remind ourselves of the truth of Romans 6:1-4, 11:
“What should we say then? Should we continue in sin so that grace may multiply? Absolutely not! How can we who died to sin still live in it? Or are you unaware that all of us who were baptized into Christ Jesus were baptized into his death? Therefore we were buried with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, so we too may walk in newness of life.
.. So, you too consider yourselves dead to sin and alive to God in Christ Jesus.“
“No Sin in Him”: Christ is our perfect Standard. Because He is perfectly pure, fellowship with Him (abiding) naturally creates a distaste for sin.
The Process of Sanctification (v. 6)
Under Construction: We will not reach perfection in this life, but we are ever-changing. The idea is the direction, not perfection, but there must be progress. If the Holy Spirit dwells in you, you truly are being transformed into the likeness of Christ.
The Holy Spirit’s Work: When the Lord brings conviction through the indwelling Holy Spirit, the true believer will change. We are growing in sanctification, moving away from rebellion and toward the “Rule” of Scripture.
Application (How We Respond)
Stop Minimizing Sin: Do not call rebellion “just a struggle.” Recognize that sin is lawlessness—a direct challenge to the King.
Expect Change: If you are “remaining in Him,” you should see a life that is practically and consistently reforming according to the Word.
Audit Your Repentance: True repentance is not just a change in vocabulary; it is a fundamental shift in the direction of one’s thinking that results in a change of behavior.
How Does This Text Point to Christ?
Jesus is the Sinless One who was “revealed” to take away our sins. He is our primary loyalty. He provides the power for our transformation through His Spirit, ensuring that we are no longer slaves to lawlessness.
Summary (Recap)
1 John 3:4–6 teaches that sin is rebellion against God’s authority. While believers still struggle with sin, they cannot remain in a lifestyle of habitual lawlessness. Because Christ came to save us from our sins, those who truly know Him will be constantly, though imperfectly, transformed into His likeness.
Be Intentional (Putting it to Practice)
The Conviction Check: Think of a recent time you sinned. Did you feel the conviction of the Holy Spirit leading you to change, or did you try to justify it?
The “Under Construction” Prayer: Acknowledge your sin to God, recognize that you often esteem yourself as higher than you ought to (Rom. 12:3), and submit to His will. Ask Him to make your growth in holiness true and observable this week.
Ask Yourself (A Deep Examination of the Heart)
The Nature of My Disobedience When I stumble into sin—whether it is an outburst of anger, a lingering anxious thought, or a “small” lie—how do I view it? Do I dismiss it as “just a struggle,” or do I see it as lawlessness—a moment where I pushed God off His throne to rule my own life?
The Root of My “Respectable” Sins Looking at the list of “subtle” sins (pride, unthankfulness, frustration, or gossip), can I trace them back to a lack of love for the Lord? If I truly loved God with all my heart in this very moment, would I still feel entitled to this bitterness or this discontentment?
The “Speck” vs. The “Log” Audit Am I more offended by the doctrinal errors or moral failures of others than I am by my own ungodliness? Do I spend more time “examining the Scriptures” to win an argument or to allow the Word to judge my own heart and motives?
The Direction of My Life If I were to look at my life over the last six months, is there any observable fruit of change? Not just a change in the words I use at church, but a fundamental shift in how I treat my family, how I spend my time, and how I handle frustration. Am I “under construction” and moving toward Christ, or am I comfortably parked in my old habits?
The Authority of the Word In my daily leadership or parenting, what is the final authority? When a conflict arises, do I rely on my “feelings,” my “subjective experiences,” or “human tradition”—or do I diligently search the written Word to see what God has commanded?
The Approval of Man Am I afraid to truly repent and change because I might lose the approval of people around me? Am I more loyal to my “tribe/tradition,” or my “ministry image” than I am to the Sinless Savior who was revealed to take away my sins?
A Closing Thought for Reflection
True repentance is not merely a change in vocabulary; it is a fundamental shift in the direction of one’s thinking and beliefs which affects everything else. If your encounter with Christ has not resulted in a life that is practically and consistently reforming, have you truly “seen Him or known Him”?
