When I explained this to a friend of mine a few years ago, he responded with the following:
Most of the "commandments," beliefs and practices we have work really great in the positive.
-Keep the Sabbath Day holy, and you will find benefit in it.
-Obey the guidance of God, and you will see Him again someday.
-Families can be forever.
-Following the Gospel will make you a better person
Most of these same things break down quickly with problems when you use them in the negative.
-Break the Sabbath Day and you will be punished.
-You won't ever see God again if you don't obey.
-You will be separated from your family and never see them again if you are not married in the temple, one chance and it's over.
-People who don't follow the Gospel are unhappy and are bad people.
"Keep a Sabbath and make it Holy. It will bring you benefits."
is much better than:
"Don't dare break the Sabbath!!"
