Relative truth creates chaos and anarchy on every level.  The firmness of the Laws of nature is evidence that there is firmness in the Laws of good and evil.  Every police department enforces laws of behavior based upon what it has determined to be destructive, because, in practice no one is actually a moral relativist. No one has ever really lived by moral relativism because every human, by nature, realizes injustice is evil, especially when someone they love is treated unjustly.

It is illogical to think that in a universe governed by laws as mathematically mind boggling and artistic as ours has no absolute moral laws. Every day the laws of nature are so predictable we can send people into space. Everyone acknowledges Newton's law of universal gravitation and every other physical scientific law. This universal acceptance of physical scientific comes in handy moment by moment, for example around the standards of measure and weight. Because of our all acknowledging truth in the physical world, we are able to trade fairly. No one says “What is a pound to you?” “How long do you feel your inch is?” On a planet like this, certainly there also exists absolute moral truths, especially given the fact that when we disregard the moral laws given by the Creator of the universe,  peace and beauty with sexually transmitted diseases, cruelty, addictions, drunk driving, stealing, laziness, murder, violence, adultery, divorce, lying, abortion, cheat, greed, pollution, rape and more.  

To the degree a culture lives life according the Bible, virtually every social problem evaporates. The collective result of living by the New Testament would be that crime would disappear, healthcare would be more unburdened to fund finding more cures, the economy would soar because productivity would go through the roof, security systems would be obsolete, the Internet safe, prisons emptied, children cherished, the earth kindly stewarded. Our national budget, freed from the financial costs created by social problems that result from sin, could use the savings to accomplish more benevolent humanitarian efforts all over the world.
