Context

“No true believer trusts in his own righteousness, but says with David, "Enter not into judgment with thy servant; for in thy sight shall no man living be justified." (Ps. 143:2) Again, "If thou, Lord, shouldest mark iniquities, O Lord, who shall stand?" (Ps. 130:3.) No man is to despair of salvation just because he is aware of the lust of the flesh. Let him be aware of it so long as he does not yield to it. The passion of lust, wrath, and other vices may shake him, but they are not to get him down. Sin may assail him, but he is not to welcome it.” source
