Sabbath Rest

The OT sabbath was an appropriate response at that time, to the fact that God rested on the seventh day.

But the reality now at this time, links us to that fact in a different, better and permanent way.

God didn't rest every seventh day: He entered into permanent rest on the seventh day. Mankind fell from that rest. The Law of the sabbath was later given to make fallen men see that a state of rest was yet to be obtained.

Jesus gave us that rest. It restores us to participation in God's state of rest. For us it's a rest from the works of the Law.
