One Objective First

There is an old story about Rabbi Levi Yitzchak of Berditchev who was challenged to show God's power in this world.  To do so he asked his servant to bring something the local ruler had declared as contraband.  After insisting on it the servant went out and eventually returned with the item.  After that he asked the servant to bring him some bread from a Jewish home, the caveat being that this occurred during Pesach.  Again the servant needed some pushing but eventually went out.  This time he came back empty handed.  Reb Levi Yitzchak triumphantly pointed out that a human rule with police and courts couldn't get people to follow his laws but God in Heaven could count on his nation to be obedient without anything to enforce His law.
Nowadays, of course, the story wouldn't have ended the same.  The servant would easily have found bread, nebich, and returned with it to his master.  We therefore have to look at this story and draw a different conclusion.
Before we can demand obedience to the Creator, we have to restore His position as our ruler.  Despite how obvious that seems, it's not a simple task at all.  Both within the frum community and without, God takes a back seat when it comes to our priorities.  We mumble about Him in our prayers, say Baruch HaShem instinctively and all that but when was the last time most of us were moved to talk privately with Him, or to mention Him without it being in some official context.  We struggle with "Gadol worship" and chassidish venerations of their Rebbe as a conduit between them and the Creator.  The extra level dulls our connection.
Outside the Torah observant world the situation is no better.  There God is an impotent, all-approving figure whose job is to reward us for our good deeds (and we'll subjectively decide on what those are) and refrain from judging us when we fail to meet His standard. 
Is this any surprise though?  In a famous story in the Midrash similar to the one above, one of our Chachamim tries the same thing with a Roman emperor, this time the challenge being for the emperor to ban all fires in the city.  At the end of the day the two stand on the roof of the palace, survey the city and see a single pillar of smoke in the distance.  Nowadays there would be dozens of such pillars and everyone would have an excuse as to why the law doesn't apply to them.  We live in a society when the cardinal rule for lawfulness is "It's only illegal if you don't get caught".  We are not so isolated as to be immune from this attitude.  Outside the frum world you can find lots of bread on Pesach.  Inside the ranks of the pious you can find crimes just as bad, just as easily.
If there is therefore to be a change within the Jewish nation, especially within Israel itself, we must ask ourselves what one simple change we can make to turn ourselves towards God and His expectations for us.  Bullying people into keeping Shabbos whether they want to or not, telling them how to use the mikveh or not, isn't doing it.  What would?
Perhaps all parts of the Jewish community need to be reminded that God is our King.  Stop, period, nothing more.  Until now we have failed to do that because of the implications that come with it.  If God is King, then how dare any of us tolerate disobedience, either within ourselves or from our brethren? 
I would suggest that the same way we see infractions of law from our fellow citizens wherever we live, citizens who nevertheless recognize the legitimacy of the government they live under and who, if forced, will therefore obey its laws, we approach ourselves in the same manner.
You can't force a person to keep kosher without his accepting that there is an Authority who demands it of him yet that is precisely what so often happens.  You can't expect a person to abandon secret sins if he is convinces that the all-seeing Eye in the Sky isn't watching him at certain times.
Before we worry about the little things, or frankly even the big ones, we have to work on re-establishing His authority.  Once all Jews recognize that, despite their level of observance or non-observance, there is a God in Heaven that we are all governed by then we can talk about bringing people around to a more proper form of behaviour.  Accept the government, then push the laws.
