Exodus 31: A Sign Forever

The Israelites are to observe the Sabbath, celebrating it for the generations to come as a lasting covenant. It will be a sign between me and the Israelites forever, for in six days the LORD made the heavens and the earth, and on the seventh day he abstained from work and rested.’” -Ex. 31:16-17 NIV

One of the things you have to say about the Israelites, or Jews as we know them today, is that they took God's commands about the Sabbath seriously.  Just like the rainbow is a sign of God's covenant with man that he will never again flood the earth, the Jews observance of the Sabbath is a sign that they have never forgotten their covenant with God.  They continue to observe the Sabbath, even as they have had to adapt it to modern   If ever you are staying in a hotel in Israel on the Sabbath, you will be aware of this when you notice that the elevators have a mind of their own from Friday sundown to Saturday sundown.  They will stop on every floor for people to board so they do not have to push the elevator buttons.  Some of us may think this is taking things a little too far, but at least they are aware of God's commands and are still, after all these centuries, trying to stay faithful to those commands.  

If remembering the Sabbath is a sign of God's covenant with the Jews, what is the sign of our covenant with him?  It might be that we are to show we love one another.  A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
By this shall all men know that ye are my disciples, if ye have love one to another. (John 13:34-35 KJV). If so, I'm not sure we have been as faithful to that covenant as the Jews have been with their observance of the sabbath.
