How important is truth in our society today?

I've been reading Truth Triumphs by Bible teacher John McArthur, and have really gained some new insights into this, which kind of helped open the door to this study.

MacArthur believes that all of life is about the truth. In fact, he believes it's the most important reality in the universe. Think about how the issue of truth is so important in all of life. Not only do we have moral, spiritual and theological truth, we also have fixed truth in the physical world that we live in.

Most rational people care about the laws of nature and science, and they realize the harm that violating those laws bring into their lives. But some of these same people are willing to split the reality of physical laws with the spiritual moral laws. 

So we have to ask, how do reasonable people do this?

The Lord gave this reply to the Israelites through the prophet Isaiah, "Because you have said, 'We have made a covenant with death, and with Sheol we have made a pact. The overwhelming scourge will not reach us when it passes by, for we have made falsehood our refuge and we have concealed ourselves with deception.'" - Isaiah 28:15

And in John 8:31-32, "To the Jews who had believed Jesus, He said, 'If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.'” >>Watch On YouTube
