Truth can be intricately connected to survival. In the case of the Christian beliefs, this is said:
14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up; 15 that whosoever believeth may in him have eternal life. 16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth on him should not perish, but have eternal life. 17 For God sent not the Son into the world to judge the world; but that the world should be saved through him. 18 He that believeth on him is not judged: he that believeth not hath been judged already, because he hath not believed on the name of the only begotten Son of God.
Like our knowledge about the truth of the workings of our technology permits us to open a car, turn the key that turns the engine on and drive to work, this way, the truth about what is real and what is a lie, can lead to life if a person follows the rules, obeys the edicts, do what we were told to do.
As my old dead father said, doing nothing will get you nothing.
