O God, who in a wondrous manner revealed the inexhaustible riches of your mercy to Saint Maria Faustina, grant, we beseech you, that by looking with trust upon the pierced side of your Son we may be strengthened to show mercy one to another and, at length, sing forever of your mercy in heaven. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, God, forever and ever.
