What is the real mean of keeping the Sabbath?

Keeping the Sabbath is an agreement or convenient. When we begin to keep the Sabbath, this indicates that we have signed an agreement, a contract, that ures God that we shall be one with Him in this way. We would be one with Him by first enjoying Him and then by working for Him, with Him, and in oneness with Him. This is an eternal covenant. It is not merely for one age, dispensation, or generation. It is an eternal agreement between us and God.
