... learning the [new] truth can be a shattering experience.
“The truth is often disagreeable, because it fails to support prejudice or myth.” The Encyclopedia Americana
Seeing our ... [past] ... beliefs exposed as untrue can be disillusioning, especially if we were taught by trusted religious leaders. Some might liken the experience to finding out that trusted parents were, in fact, secret criminals.
But is not finding out religious truth better than living under a delusion? Is it not better to know the facts than to be manipulated by lies?
When it comes to physical realities, such as medicine, mathematics, or the laws of physics, even the staunchest relativist will believe that some things are true. Who of us would dare to ride in an airplane if we did not think that the laws of aerodynamics were absolute truths? Verifiable truths do exist; they surround us, and we stake our lives on them. ( All of above texts quoted from: 1995 The Watchtower, July 1, par. 5,7 & 8 )
Don't stake your lives on metaspiritual truths!
