Q-A: Should Christians uphold the Sabbath?

This question has been asked in the past, and as a spin-off from the content in this video regarding what 'Law' means in the Grace Dispensation, I thought I'd add it to the Q&A section of this site.

In Exodus 20:8-11, the bible defines the Sabbath law, that it was an absolutely required ordinance to keep. As a matter of fact, it carried the death penalty for anyone who broke this law. In Numbers 15:32-36 we encounter someone picking up sticks on the Sabbath and even this simple or mundane task incurred the fateful sentence.

This law (as with all the other Mosaic laws) would remain in force throughout the Old Testament, into the Gospels, and even into Acts. It was only suspended after the Jerusalem Council Meeting in Acts 15 where Paul's grace gospel and doctrine became the new and only valid instructions from God from that time on (see 1 Corinthians 14:37). Paul emphatically taught in Romans 6:14 that we are not under the law, but under grace, so this Sabbath law, as a required observance, does not apply anymore to the Body of Christ. Paul, in his epistles, clearly teaches that we do not have to keep the sabbath:

Romans 14:5 "One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind. 6 He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it ...."

Colossians 2:16, "Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days ...."

So, to summarize, keeping the Sabbath was a commandment for Israel under the law dispensation, but for us under the grace dispensation, it is not a commandment, but something that we have the liberty to practice or not, according to our personal convictions.
