Isaiah 56

It took me about 2 minutes to read this chapter. There was one phrase that God used twice in this chapter that caught me attention. It is "who keep my Sabbath...". Both times that it is used it is connected to a group of outsiders of God's covenant with Israel. In both cases God uses this test to show a people approved by God. So what does it mean to keep God's Sabbath? The simplist definition is to weekly suspend that activity which gives you your livelihood for one day as an expression of honor and dependance on God. While was this such a vital test? I think that such an action would be an outward display of a persons complete dependance upon God. In Isaiah's day not earning money on one day of the week could mean no food the next day. So to give up a day of work was a powerful statement of a person's faith that God would provide for their needs.
