1 John 1:10

“, &c.] Have never sinned, in time past as well as now; deny original sin, and that men are born in sin, but concupiscence is not sin; and so not regarding internal lusts and desires as sinful, only what is external, fancy they have so lived as to have been we make him a liar: that is, God, who in his word declares that the wicked speaking lies; that his own people are transgressors from the womb; that all have sinned and come short of his glory; and that there is none that does and become filthy by it, and so obnoxious to the wrath of God: and his word is not in us word of God which declares these things; no regard is had unto it; it “is not with us”, as the Ethiopic versions render it; it…”

“Parallel to Jo1 1:8. we have not sinned--referring to the commission of actual sins, even after regeneration and conversion; whereas in Jo1 1:8, "we have no sin," refers to the present GUILT remaining (until cleansed) from the actual sins committed, and to the SIN of our corrupt old nature still adhering to us. The perfect "have . . . sinned" brings down the commission of sins to the present time, not merely sins committed before, but since, conversion. we make him a liar--a gradation; Jo1 1:6, "we lie"; Jo1 1:8, "we deceive ourselves"; worst of all, "we make Him a liar," by denying His word that all men are sinners (compare Jo1 5:10). his word is not in us--"His word," which is "the truth"…”

“If we say that we have not sinned - In times that are past. Some perhaps might be disposed to say this; and as the apostle is careful to guard every point, he here states that if a man should take the ground that his past life had been wholly upright, it would prove that he had no true religion. The statement here respecting the past seems to prove that when, in 1 John 1:8, he refers to the present - “if we say we have no sin” - he meant to say that if a man should claim to be perfect, or to be wholly sanctified, it would demonstrate that he deceived himself; and the two statements go to prove that neither in reference to the past nor the present can anyone lay claim to perfection. We make…”

“Yet still we are to retain, even to our lives' end, a deep sense of our past sins. Still if we say, we have not sinned, we make him a liar - Who saith, all have sinned. And his word is not in us - We do not receive it; we give it no place in our hearts. Next: 1 John Chapter 2”

“1:10 If we claim we have not sinned, we are calling God a liar: God’s word emphasizes the permeating and penetrating nature of sin (see study note on 1:8).”

“we say: Jo1 1:8; Psa 130:3 we make: Jo1 5:10; Job 24:25 his word: Jo1 1:8, Jo1 2:4, Jo1 4:4; Col 3:16; Jo2 1:2 Next: 1 John Chapter 2”
