Do you understand your worship in the Mass as a form of sacrifice?

Try preparing for Sunday Mass by reading some of the todah psalms (for example, Psalms2269; and 116). See if this helps to deepen your appreciation of the Mass.

Do you understand life as an offering of obedient sacrifice to God?

Read and pray over Psalms 40 and 50 and the story of the Maccabeean martyrs (see 2 Maccabees 6:12-7:40). Ask for the strength to make yourself an ever more acceptable offering to the Lord.
