The Sign of our Faith

I am currently reading Pathway to Our Hearts: A Simple Approach to Lectio Divina With the Sermon on the Mount by Archbishop Thomas Collins.

I came across this quote today that seemed particularly appropriate for Lent:

Our faith does not tell us that life will be a happy, happy time. "Have a nice day" is not our prayer. The happy face is not our sign. Our sign is the cross of Christ.
