A great quote from a book review by Katie Galli in the April 2008 issue of Christianity Today:
Yes, we're Americans. We multitask all day long. Efficiency is one of our top cultural values. I, too, am pragmatic. I'd like to use Sunday morning to worship God, to get a few pointers on how to improve my relationship with Jesus, and to reconnect with community. But every Sunday, the first words I hear are, "Blessed be God: Father, Son, and Holy Spirit." And I'm reminded that we gather weekly not to hear a practical talk on how to better live out our faith or to provide a venue to tell our friends about Jesus. We gather to corporately worship God, to celebrate the redeeming work of Christ on the cross, and to remember that our lives are not about us.
