is it a sin to take off 2 days a week?

I heard something taught last week that I’d like to run by you.

Kind of out of no where, I heard a respected teacher say that if we take 2 days a week off, we are breaking God’s commandments regarding Sabbath. This was based on what Scripture says in Exodus: Observe the Sabbath day, to keep it holy. Work six days and do everything you need to do. But the seventh day is a Sabbath to God, your God. Don’t do any work—not you, nor your son, nor your daughter, nor your servant, nor your maid, nor your animals, not even the foreign guest visiting in your town. For in six days God made Heaven, Earth, and sea, and everything in them; he rested on the seventh day. Therefore God blessed the Sabbath day; he set it apart as a holy day. (MSG)

While the speaker did not elaborate, I assume that he was not teaching that we have to work on our jobs 6 days a week. The topic was productivity and prosperity and he was saying that it is no wonder that we are not more productive if we lose 1/6th of our work time. Most people I know work 5 days a week and then spend one of their two weekend days off working at home: landscaping, cleaning, cooking – the stuff that makes life flow the rest of the week.  Of course, we all know people who never take a day off which is clearly not what God planned. The speaker did not discuss the number of hours we work per week.

I almost always work 6 days a week, but I found myself a little defensive when I first heard the teaching. I’ve been processing it since then. And I can’t come up with a Biblically based argument to refute what the guy said.  If you disagree with the speaker, don’t shoot me – I’m just the delivery boy. But I’d like some input from others.

One thing I know for sure: there are lots of people who work on their job 6 days a week and then take God’s day, the Sabbath, as their day off. They can’t worship God because they need a break form their work. That, for certain, is wrong.

Any feedback?
