"The saints are at the same time sinners while they are righteous: righteous because they believe in Christ, whose righteousness covers them and is imputed to them; but sinners because they do not fulfill the law and are not without concupiscence. They are like sick people under the care of a physician: really sick, yet healthy in beginning and in hope—or rather, being made healthy."

"In chapter 8, St. Paul comforts fighters such as these and tells them that this flesh will not bring them condemnation. … The Holy Spirit assures us that we are God's children no matter how furiously sin may rage within us, so long as we follow the Spirit and struggle against sin in order to kill it."
