Every time we rest upon the seventh day, as God did at creation, we commemorate the grand event. It was given to Adam, the head of the human race. Hence through him, as our representative, to all nations. It is not a Jewish institution, for it was made 2,300 years before ever there was a jew. Men should be cautious how they stigmatize God's holy rest day.
Evident reference is made to the Sabbath all through that patriarchal age.
It was a part of God' s law before Sinai. Then God placed it in the heart of His moral law. The seventh-day Sabbath was commanded by the voice of the living God. Then He wrote the commandment with His own finger. He engraved it in the enduring stone, indicating its imperishable nature.
