Verse 10: If we say that we have not sinned, we make Him a liar and His word is not in us.
This is John’s fifth and final conditional statement of verses 6-10. It is easy to mistake that this verse seems to repeat the content of verse 8. However, to be clear, verse 8 considers the sin principle—the old sin nature, “the old self” (Romans 6:6; Ephesians 4:22); whereas this verse is regarding sins in particular—deeds which violate “His commandments” (1 John 2:4).
John’s Fifth Premise
Again, the word “if” expresses the probability of someone who may believe that they no longer commit sinful deeds. And just as John stated in verse 8 that the self-deceiving one believes he is no longer controlled by the principle of sin, this is an example of the same self-deception. The Greek tense of the verb ‘sinned’ emphasizes that sinning has current consequences for the believer, specifically the loss of fellowship with God.1 Most likely this believer has been influenced by the heresy of perfectionism and is oblivious of how disastrous this false teaching will have on their spiritual life. Dr. L.S. Chafer correctly observes that:
Scripture gives no basis for the extreme doctrines of personal holiness or sinless perfection advocated by some Christians.2
Nowhere in God’s Word is credibility given to the belief that once a person believes in Jesus Christ, that their old sin nature is eradicated and that they no longer commit sins. Dr. Norman Geisler points out:
[The] belief that we can reach a point of sinless perfection (whether by eradication or not) in this life is unbiblical, unrealistic, contrary to experience—and it minimizes sin. Perfectionism is a quick-fix scheme, can lull a person into a false sense of spiritual attainment, and undermines the God-ordained gradual process of sanctification.3
What Geisler means by the “gradual process of sanctification” is the developmental process for the believer to attain spiritual maturity. Apostle Paul defined this “God-ordained” process as the work of the pastor-teacher:
For the equipping of the saints for the work of service, to the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. (Ephesians 4:12–13 [emphasis added])
The writer of the letter to the Hebrews states that “solid food is for the mature” believer (Hebrews 5:14a). This solid food is what God intended the pastor-teacher to provide the believer. For when they apply (practice) what they learn, their spiritual senses are therefore “trained to discern good and evil” (Hebrews 5:14b).
The question is: would a believer who claimed to be sinless need training to distinguish what is good or evil? Adding to this absurdity, there would also be no purpose for the “God-ordained” pastor-teacher.
John’s Conclusion
John, exercising his apostolic authority, asserts that if we dare to claim that we no longer sin, then we make God out to be a liar. This word ‘make’ means to produce, or to cause, bring about, accomplish.4 Those who claim that they “have not sinned,” they intentionally or unwittingly embrace this heresy of perfectionism. And what is worse, by their nonchalant assertion they are blasphemously declaring that the God of the universe is a liar.
Please note how John concisely explains the reason we can make God a liar if we were to embrace this heresy: “His word is not in us.” By the use of the Greek verb “is”, we have in this phrase an absolute statement of truth. If it were possible to probe the memory center and stream of consciousness of this person, the doctrine of personal sin would nowhere be found. The writer of Hebrews describes that this is exactly what the Word of God is designed to do.
For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. (Hebrews 4:12)
Therefore, if we were to say that we have not sinned, then we either have not studied God’s Word or we have not believed and have disputed and disregarded the authority of God’s Word for our lives.
As already mentioned there are no Scriptures to support this heresy; in fact there are many passages in God’s Word that dispute perfectionism. The Word clearly states “For all have sinned and fall short of the glory of God” (Romans 3:23; cf. Romans 3:9-19). Solomon also declared this:
Indeed, there is not a righteous man on earth who continually does good and who never sins. (Ecclesiastes 7:20; cf. 1 Kings 8:46)
And Solomon incredulously asked:
Who can say, “I have cleansed my heart, I am pure from my sin?” (Proverbs 20:9)
On this verse Dr. Ryrie astutely remarks that “The implied
answer is ‘nobody,’ thus teaching the impossibility of sinless perfection.”5
Who is the Liar?
Briefly looking ahead, John says that in reality the liar is the one who “does not keep His commandments” and that “the truth is not in him” (1 John 2:4). We can conclude that the phrases “His word is not in us” and “the truth is not in him” are synonymous because of the Lord Jesus’ proclamation to the Father: “Your word is truth” (John 17:17).
Notice Our Lord’s confrontation with the Pharisees when He asserted that the devil is the liar:
“You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.” (John 8:44 [emphasis added])
God is not the liar, as the Apostle Paul maintained “let God be found true, though every man be found a liar” (Romans 3:4).
