This morning at Mass, Father observed that in today's first reading from the book of Sirach, the phrase "fear of the Lord" was repeated four times. And he explained that God is not someone we are to be terrified of, like something in a horror movie. That's not what fear of the Lord is all about.
He recommended that this Lent, we all practice growing in the virtue of fear of the Lord: wondering at the mystery of God and all that He created. He said that the more you grow in this virtue, the more awesome you understand God to be.
