Everything, every choice and every action has a reason for happiness or pleasure.Following our desires we can choose something that could be harmful to other or could be a waste to our own self.But Laws are the only things to follow that have no motivations from likeness or dislike.These are the only path which have a genuine reason for their presence and that is "just because they are".In every time we can find a messenger from GOD to put before us the laws which we call the "Religion".GOD has made them.So that we can follow and guide a life in a manner to ensure peace and harmony in the world so that the love grows forever.If this is the only reason for the laws than Islam is the best religion.
