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.
There are many things in this life that are not sinful in and of themselves, but when they are misused they can be deemed as sinful or harmful.
Thrones and empires are terminated because of the unruly evil of sin. As such, they rise or fall based upon their choice to sin or their refusal to partake therein.
