We all know how Chuck-E-Cheese works: you play games, earn tickets, and then, at the end of your time, use those tickets to redeem a prize. It's a fun place, but hopefully the concept is not something we maintain in our spiritual lives. That is, hopefully we don't see our spiritual endeavors as simply means to an end.
During this season of Lent, the Church proposes to us three special devotions: prayer, fasting, and almsgiving. These are like the games at Chuck-E-Cheese. The temptation is to "do" these "things"—or anything in our faith lives, i.e., going to Mass, Confession, etc.—so we can get enough tickets to get to heaven. What a strenuous proposition! Does that mean if we eat a chicken McNugget on Friday we go to Hell?
