Regret that you are able to do so little for the glory of the three Divine Persons in return for all that they have been to you and have done for you. Regret your past negligence and forgetfulness. Praise each Person separately for His special benefits to you.
Above all assist at the Holy Sacrifice of the Mass, in which you can unite with the Adorable Victim in rendering to God an adequate adoration, and gratitude, and reparation for your sins.
