For in six days the LORD made heaven and earth, the sea, and all that in them is,
and rested the seventh day:
wherefore the LORD blessed the sabbath day, and hallowed it.
Exodus 20:11
"God set apart the seventh day in Paradise.
---This proves that the observance of the Sabbath is not a carnal 
ordinance, for it was instituted before sin entered our world.
---But the most remarkable fact that appears in this record is, that this memorial was needed even in the garden of God.
Though man could converse with God face to face, yet every week, by the most impressive act, Adam was called to remember and acknowledge God as his creator.
---The rest-day of God was set apart, not as a mere rest from wearisome toil, for Adam had almost as little occasion for rest from weariness in Paradise, as had the Creator from his work of infinite might, but as a day when man should desist from everything else and think of God." J.N. Andrews
