In times past, most of us knew the difference between right and wrong. Today, many think that they can decide what's right or wrong for themselves.
We know it as Moral (or Ethical) Relativism. It's defined by Oxford Reference as “The doctrine that knowledge, truth, and morality exist in relation to culture, society, or historical context, and are not absolute.“ In other words, anything goes.
“This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil.” (John 3:19 NIV
“Faith teaches that there is a right and wrong beyond mere opinion or desire. Most importantly, it teaches us that freedom is not an end in itself, that how freedom is exercised matters as much as freedom itself.“ Stephen Harper
When moral relativists are told that what they're doing is wrong, they answer, “Says who?” They believe they are the final authority of their life, that there's no higher authority over them.
“Therefore whatever you have said in the dark shall be heard in the light, and what you have whispered in private rooms shall be proclaimed on the housetops.“ (Luke 12:3 ESV)
A society that allows individuals to make up their own rules, and insist that sin isn't sin, is a society on the brink of moral collapse.
“If there is no absolute moral standard, then one cannot say in a final sense that anything is right or wrong. By absolute we mean that which always applies, that which provides a final or ultimate standard. There must be an absolute if there are to be morals, and there must be an absolute if there are to be real values. If there is no absolute beyond man's ideas, then there is no final appeal to judge between individuals and groups whose moral judgments conflict. We are merely left with conflicting opinions.“ Francis Schaeffer
“Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” John 8:12 ESV
“Christianity seems at first to be all about morality, all about duties and rules and guilt and virtue, yet it leads you on, out of all that, into something beyond. One has a glimpse of a country where they do not talk of those things, except perhaps as a joke. Every one there is filled full with what we should call goodness as a mirror is filled with light. But they do not call it goodness. They do not call it anything. They are not thinking of it. They are too busy looking at the source from which it comes.“ C.S. Lewis
