1. Johannes 1:10

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" (Jo1 1:8), accuses us truly; by denying it we drive it from our hearts (compare Joh 5:38). Our rejection of "His word" in respect to our being sinners, implies as the consequence our rejection of His word and will revealed in the law and Gospel as a whole; for these throughout rest on the fact that we have sinned, and have sin. Next: 1 John Chapter 2

Evidence given concerning Christ's person and excellency (Jo1 1:1, Jo1 1:2). The knowledge thereof gives us communion with God and Christ (Jo1 1:3), and joy (Jo1 1:4). A description of God (Jo1 1:5). How we are thereupon to walk (Jo1 1:6). The benefit of such walking (Jo1 1:7). The way to forgiveness (Jo1 1:9). The evil of denying our sin (Jo1 1:8-10).

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).
