1 John 1:10

10. This concluding verse is added, as parallel and completing to 1 John 1:8, in order to emphasize the fact that not only is the denial of sin as a state, but of sin as an actual commission and practice in the past, flagrantly false.

Have not sinned The applying this to the Christian (as Alford and Huther) is, as above on 1 John 1:8, clearly erroneous. If the supposition be that the Christian says, I have not sinned since my conversion, no sensible Christian ever said that, and the admonition is absurd. If it be, I have not sinned in a particular case, it may be true. Clearly, John is laying the foundation of conversion of sinners to Christ in deep confession of sin both of character and act.

Make him a liar For both the universal condemnation of men and their universal redemption through Christ, is based upon the assumption that all men, of full responsible age and powers, have sinned.
