Rest, Joy, and Holiness

Sabbaths come once each week. After 6 days of working and cleaning and all my commitments, the Sabbath comes.

Hebrew4Christians provides a wonderful summary of the Sabbath. Even if one were to brush off the more Jewish side to the Sabbath (which I don't recommend), there are benefits to it. There are three component parts to the Sabbath:
1. Rest
2. Holiness
3. Joy

We are commanded to remember the Sabbath day and to keep it holy. It is one of the 10 commandments. I reserve Saturday as my Sabbath. On Saturdays, I can sleep in (a blessing), take a break from my academic and domestic pursuits, and delve more into the Word.

I make an effort to rest (sleeping in and not studying/completing chores).

I make an effort for holiness (reading the Word...or working on Biblical blog posts). I put aside things that don't direct my thoughts toward God.

I make an effort of joy (candles, and tea, and bubble baths, and leisure reading). The Sabbath is not a restrictive list of "Don't do_____," but rather it's permission to rest and a celebration.

Do you keep a Sabbath?
What do you consider to be integral/core to celebrating the Sabbath? i.e. what are the key components?
