13. Learn, therefore, O man, duly to look into, and rightly to consider the abominable filthiness of _Original Sin_, as the sink of all abomination. For by this the hereditary righteousness of God was lost, and the hereditary unrighteousness of the devil transplanted into men. Hence the sinner was cast away from God, and doomed to an eternal death: and this he must certainly undergo, except he obtain forgiveness of sin for Christ’s sake through faith. 14. But to set the state of fallen man, both as to soul and body, in as clear a light as possibly I can, I think it well to give a fuller description thereof in this place; most earnestly entreating every one, for the sake of God and of his own eternal salvation, to ponder again and again, and seriously to revolve in his mind that original depravity which has corrupted our nature. The consequence of this will be, that as a man beholds his bodily face in a glass, and knows it, so he may also behold in himself his own wretchedness, and original sin. This will daily influence him to lament his own distressed condition, and to sigh after Him, who alone is able to heal us. 15. For the whole Christian life is indeed nothing else, than a constant wrestling with original sin, and a continual purging away of the same by the aid of the Holy Ghost, and by true repentance. For, in proportion as any one mortifies his natural propensity to evil, in that degree is he renewed after the image of God, even day by day; and they who are not inwardly mortified by the Holy Ghost, are at best no more than hypocrites, let them make ever so great a show with an external profession of the Christian faith. Neither can they expect to enter into the kingdom of God, since they are not renewed into his image: for whatsoever is not dead to itself, nor renewed into the image of God by his Spirit, is altogether unfit for that glorious state.
