All the joys and sufferings in one's vocation (Holy Orders, Single Life, Religious Life or Married Life)
A deed that one has done through the use of one's talents
The joyful and sometimes tedious aspects of human life (going to school, going to work, cleaning the house, going shopping, going to a doctor appointment, spending time with family and friends, etc.)
The time spent prayerfully studying one's faith
The time spent piously praying devotions
The time spent in a Holy Hour with the Eucharistic Christ
The time spent worshiping Jesus during the pious devotion of Benediction
The deed of doing penitential acts, such as abstinences, fasts, reparations and charitable giving
An example of a prayer you could offer in the silence of your heart to Jesus when offering yourself to Him at Mass
Jesus, I offer to You at this Mass my words and actions. Please accept my offering and use it as a means for the clergy to be increased in holiness. Amen.
