Paul & Sabbath Glue in Hebrews 4: Inverse Relationship

Paul is talking about both Justification & Sanctification
The TWO go hand in hand as True Righteousness by Faith

*In Exodus 20:8-11
SANCTIFICATION/Obedience - (For in six days the LORD made heaven and earth,...But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work,..) 

Physical Rest.
---Or--- as Paul says For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. Hebrews 4:4

* In Deuteronomy 5:12-15 

JUSTIFICATION/Grace - (And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.) 

Spiritual Rest.
---Or--- as Paul says For he that is entered into his rest, he also hath ceased from his own works, as God did from his. 

Hebrews 4:10

SUMMARY: 
Sabbath is the Glue of God's Law....the Inverse Relationship of Justification & Sanctification
