From the Fathers

"It is always possible to make a new start by means of repentance. 'For a righteous man may fall seven times And rise again' (Prov. 24:16). And if you fall again, then rise again, without despairing at all of your salvation, no matter what happens. So long as you do not surrender yourself willingly to the enemy, your patient endurance, combined with self-reproach, will suffice for your salvation. 'For we ourselves were also once foolish, disobedient,' says St. Paul, '...not by works of righteousness which we have done, but according to His mercy He saved us' (Tit. 3:3,5)."
