1 John 1:8-10

If we say Before Christ's blood has cleansed us; that we have no sin To be cleansed from; or if, even after we have experienced the cleansing virtue of his blood, and are acquitted through the merit of it from all past guilt, and saved from all evil tempers, words, and works; if, even after this, after we are both justified, regenerated, and sanctified, we say we have no sin, but are perfectly sinless, and that our spirit and conduct can bear the scrutiny of God's holiness and justice, as exhibited in his spiritual and holy law; we deceive ourselves And that in a very capital point; and the truth is not in us Neither in our mouth nor in our heart; we must be destitute even of that self-knowledge which, in the nature of things, must necessarily precede every other branch of experimental and practical religion. If we confess our sins With penitent and believing hearts; he is faithful Having promised this blessing by the unanimous voice of all his prophets; and just Surely then he will punish: no; for this very reason he will pardon. This may seem strange, but, upon the evangelical principle of atonement and redemption, it is undoubtedly true. Because when the debt is paid, or the purchase made, it is the part of equity to cancel the bond, and consign over the purchased possession; both to forgive our sins To take away all the guilt of them, and to give us peace with himself, and peace of conscience; and to cleanse us from all unrighteousness From all iniquity of heart and life, and to purify our souls from all vile affections and unholy dispositions, from every thing contrary to the pure and perfect love of God. 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 give it no place in our hearts.
