The answer
St. John Chrysostom gives us a few examples of short prayers:
O Lord, of Your heavenly bounties, deprive me not.
O Lord, forgive me if I have sinned in my mind or my thought, whether in word or in deed.
O Lord, deliver me from every temptation and from eternal torments.
O Lord, enlighten my heart which evil desires have darkened.
O Lord, see the feebleness of my soul, and send down Your grace to help me, that I may glorify Your name.
O Lord, sprinkle into my heart the dew of Your grace.
O Lord, receive me in penitence and forsake me not.
O Lord, give me tears and remembrance of death, and contrition.
O Lord, give me humility, chastity, and obedience.
O Lord, give me patience, magnanimity, and meekness.
O Lord, let Your will be done in me, sinner, through the intercessions and prayers of the pure Virgin Saint Mary and all Your saints, for blessed are You unto the ages. Amen.294
