And God blessed the seventh day, and sanctified it: because that in it He had rested from all His work which God created and made. Genesis 2:3
"The Ten Commandments uses the Sabbath to show that Creator and creature, God and mankind, share something.
They share action in a continuity of time;
that is, God’s action is linked to our history.
---It demonstrates the basis for real fellowship.
Also pivotal is that Creator and creation are separate.
---It is in the creation done within real history that God shows He is distinct from but present and active in the world we live in.
