For look not now at the nature of the sin, that it is little, but that it becomes a root of great sin when neglected. For if one may say something marvellous, great sins need not so much earnestness, as such as are little, and of small account. For the former the very nature of the sin causes us to abhor, but the little sins by this very thing cast us into remissness; and allow us not to rouse ourselves heartily for their removal. Wherefore also they quickly become great, while we sleep. This one may see happening in bodies also.
