Objective Truth vs. Postmodernism

"There is such a thing as objective truth. 

Jesus said, ‘I am the way, and the truth, and the life. No one comes to the Father except through me’ (John 14:6). 

But postmodernism, for example, denies objective truth. 

One example is, “What’s true for you is not true for me”. 

So maybe they should try jumping off a cliff to see if the Law of Gravity is true for them." CMI
