~ Words of the Church Fathers ~
Since it is likely that, being men, they would sin every day, St Paul consoles his hearers by saying “renew yourselves” from day to day.
This is what we do with houses: we keep constantly repairing them as they wear old. You should do the same thing to yourself.
Have you sinned today? Have you made your soul old? Do not despair, do not despond, but renew your soul by repentance, and tears, and Confession, and by doing good things. And never cease doing this.
