Our Byzantine rite brothers and sisters will use this prayer every day during Lent. It is attributed to an early Church Father, Saint Ephrem of Syria.
O Lord of my life, take away from me the spirit of laziness, faintheartedness, ambition and idle talk. But grant me rather the spirit of chastity, humility, patience and love. Yes, O Lord and King! Grant me to see my own sins and faults and not to judge my neighbor, for you are truly blessed forever. Amen.
