God expects His people to avoid unholy practices (i.e., divination, observing of times, witchcraft, wizardry, necromancing) that ensnare the world.
Sin is not to be considered a light matter. In other words, it is not to be mocked. Only a fool would demonstrate this kind of behaviour toward sin.
People in the world are generally quite self-centered. Even saved people are often lovers of their own selves instead of preferring one another.
