If we say that we haven't sinned, we make him a liar, and his word is not in us.
(11) there is no sin so great that it may not be removed by the blood of the atonement, 1 John 1:7, “last clause.” This blood has shown its efficacy in the pardon of all the great sinners who have applied to it, and its efficacy is as great now as it was when it was applied to the first sinner that was saved. No one, therefore, however great his sins, needs to hesitate about applying to the blood of the cross, or fear that his sins are so great that they cannot be taken away!
