The Mass is the best means we have:
1. To render God the highest form of worship.
2. To thank Him for all His blessings.
3. To make reparation for all our sins.
4. To obtain all the blessings we desire.
5. To release souls from purgatory and to shorten our own time there.
6. To preserve us from all dangers to soul and body.
7. To be consoled at the hour of death, for at that moment their memory will be our greatest consolation.
8. To intercede for us at the Judgment Seat of God.
9. To bring down God's blessings; therefore, try to assist at Mass
every day, or as often as possible, and, of course, on Sundays.
10. To better understand the sublimity of the Passion of Christ, and, therefore, to increase our love for Him.

Saints comments about the power of mass:
Any time my family life falls apart, I know it's time to get to confession and get the kids back to daily mass. Dear Lord help me to be a good and holy mom...and help my children love daily mass and never commit a mortal sin!
