John Calvin on 1 John 1:10

10 We make him a liar He goes still further, that they who claim purity for themselves blaspheme God. For we see that he everywhere represents the whole race of man as guilty of sin.

Whosoever then tries to escape this charge carries on war with God, and accuses him of falsehood, as though he condemned the undeserving. To confirm this he adds, and his word is not in us; as though he had said, that we reject this great truth, that all are under guilt.

We hence learn, that we then only make a due progress in the knowledge of the word of the Lord, when we become really humbled, so as to groan under the burden of our sins and learn to flee to the mercy of God, and acquiesce in nothing else but in his paternal favor.

CHAPTER 2

1 John 2:1-2

1. My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:

1. Filioli mei, haec scribo vobis, ut non peccetis; quod si quis peccaverit, advocatum habemus apud Patrem, Jesum Christum justum:

2. And he is the propitiation for our sins; and not for ours only, but also for the sins of the whole world.

2. Et ipse est propitiatio pro peccatis nostris, non pro nostris autem solum, sed etiam pro totius mundi.
