Re: How do you want Christians to ~keep~ the Sabbath?

"I would like to keep the Sabbath," says one, "but my business will not let me." Well, if this is really the case, then get some other business that will not hinder. If you saw that your present business was greatly injuring your health, and would cause your death in a few months unless abandoned, you would lose no time in changing your occupation. But by disobeying God you lose his favor, and this will bring eternal death.

I have two questions:

1. What is a Sabbatarian?

2. Didn't the death and resurrection of Jesus Christ atone for my sins and fulfill the law? You mean that if I'm born again and living full force for Jesus Christ yet I don't keep the Sabbath I will lose God's Favor and fall into eternal death?
