Why is "The Truth" constantly changing?

The truth never changes at all ever. But, our perception of "the truth" does constantly. So, what was normal "Truth" in the 1950s (or in 1200) is not the truth most people believe today.

For example, in Christianity many people see through elements used to manipulate and enslave people down through the ages by tyrant kings and queens to make ignorant people so terrified they were permanently enslaved in unhealthy ways.

So, over time people have become more enlightened. This has also happened not just in Christianity but also  in Islam and Hinduism and Buddhism and all religions on earth.

Often ministers and priests of these religions get very upset about the "Ages of Enlightenment" where people learn Critical thinking and develop ways to think themselves out of the blinders placed there 1000 or 2000 years ago by those interested in enslaving the masses for one reason or another.

It doesn't mean that Jesus or any leader of any religion was a bad person at all. What it means is that tyrants and despots have misused these religions against their peoples and many have died and suffered for hundreds and thousands of years because of this.

So, those that learn critical thinking in this sense save the world from further torture, death and mental and spiritual enslavement.

It's not that everyone should not believe in God or religion. It is that if they are going to be religious they should do so wisely and not in a way that they are enslaved by bad or unscrupulous people. So they aren't just swindled out of their money by charlatans who only want their money for themselves and not for any good purpose in the end.

So, like I said, "The truth never changes" but people slowly but surely through experience and education become wiser every single day around the world.

One of the tools is a smartphone.

A true statement about this is that a child with a smartphone now has more information instantly at his or her fingertips than President Clinton did when he was President of the United States from 1992 until 2000.

Children are learning how to find the truth around the world with smart phones every single day. And the statement "And a little child shall lead them" takes on new meaning now with 5 billion cellphones now on earth at this point or more.
