Every nation, if it is to be considered not to be a rogue nation, is a nation filled with laws. However, these laws must not be arbitrary or capricious in nature; they must be instead of a reasonable nature, equally applied to all and consistent with natural law as well as the reasoned revelation of God's law. The invoking of God when it comes to law, is something that brings unease to certain peoples along with people and countries having different interpretations of what God's law is in the first place, but know this that God in His essence is always a force for the common good and no respecter of persons. It is of vital importance to understand too, that law must have its foundation in a principle that is unchanging, immutable, and correct, for that law to be of truth. This means that those that believe that mankind is the measure of all things, will never be able to bring true justice and law into the courts of life, because mankind devoid of any divine light, is unable to correctly and thoroughly comprehend just law because he reasons from error to error.
Islamic Sharia law at its core uses both the Quran and the Sunnah to render legal judgments in accordance with the interpretations by Islamic judges of these writings, for familial as well as criminal proceedings. The legality of Sharia Law varies from country to country, to which in some countries it is not considered law at all, to those countries that have a blended system or special circumstances that allow Sharia law, as well as to nations that Sharia law is indeed the law of the land. As might be expected, many opinions and articles have been written about Sharia law, its dangers, its misinterpretation, its intolerance and so forth, of which there is much controversy and debate.
The thing is, though, that many nations have many laws that are considered to be offensive or inhumane or just plain wrong; on the other hand there are also many nations that have good laws and a valid rule of law that protects its citizens, and provides justice for all. If the point of the criticism of Sharia law is to point out the inconsistencies and unfairness within the law, that has its merit; if on the other hand, the point is simply to demonize Islam, and Islamic Sharia law, in and of itself, without a thorough vetting of Sharia law, that is an unworthy attack upon another culture and belief.
There are many people that believe that where Islam goes, Sharia law soon follows right behind it, and they fear Sharia law and its effects, without taking the time to comprehend it. Further to this point, too many people believe that somehow Sharia law will crowd out constitutional law, and will become either the law of the land, or to somehow create dual laws within that land. All of this speaks to one very large point, which is the necessity to understand what law is in the first place and how it works within your country, and subsequently to know that good law comes both from the consent of the governed as well as in accordance with eternal law which never will change.
