If any character in Scripture reflects American culture, maybe it's Martha. Busy, busy. Lots of activity. As Luke puts it in chapter 10: "Distracted by all the preparations that had to be made" (v. 40) and "worried and upset about many things" (v. 41). She holds to the opinion that she is such a hard worker, and her sister is a slackard.
Which brings us to Mary. What's she doing while there is so much preparation to make? She is sitting! Inactive. What a waste of time! How can you accomplish things when you're sitting?
Well, according to Jesus, there are times when that is the best thing we can do. Because Mary was sitting before the Lord. At his feet. Listening to him. And Jesus tells Martha that Mary "has chosen what is better."
Let's remember that during this busiest of times -- to chose what is better.
