Do Sabbath Keepers KEEP the Sabbath?
They certainly do not if they recognize Isaiah 58 as their guide.
13 If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the Lord, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:
14 Then shalt thou delight thyself in the Lord; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord hath spoken it.
Israelites failed to keep the day Holy, so why do people today believe they can do better?
One of the reasons I never really enjoyed the Sabbath is because I was honest with myself. After the Sabbath I would critique myself to see how well I "behaved". My thoughts and words and sometimes even my actions kept me from what I believed was the standard for keeping Sabbath, Is 58. In actuality, all I was doing is putting on a good front to my peers. After a while, I learned they were doing the same thing. So much for trying to cover up what in reality I could not ever do. The cover-up was the real sin. What a relief it was when I found out that Christianity isn't about keeping ritual days given only to the now-defunct nation of Israel. I still rest from my labor, but my real rest is in Jesus.
The command was not only to rest on the Sabbath, it was also about working not five but six days a week. How many who believe the 10 are their guide are working six days a week?
