Receiving messages from the future as voices in your head.
Voice of Prophecy
It is often believed that prophets receive true prophecy through voices that only they hear, indicating that such a voice might only exists in their head.
If there is any link between time travel technology and prophecy then what could we possibly say about such a communication technology, is there any way that we could know how it would work or look like?
Lets take the point of view that the technology responsible for sending messages to the past is based on sending a 'voice of prophecy' right into a prophets head.
The first thing that might be noticed, is that it reduces a prophet to no much more than a passive listener, just picking up and hearing voices in his head.
Such a technology could cause literally and verbally cause headaches. At first, it seems efficient from the point of view that the receiver does not need to do anything, just sit back, concentrate, pray or meditate.
But at the same time, it must be a very ineffective, useless communication technology as no one is going to believe the receiver without convincing proof.
Hearing voices in your head is generally an indication of a medical problem, not communication from another dimension.
Convincing people that voices in your head come from anywhere else then your own imagination will be a mayor exercise. It is hard to proof that you realy received something, and of course, if you like, it is equally hard for others to proof it did not happen.
If you have the amazing ability to convince people that you really received prophecy in your head, then you might consider to rather use this ability to convince yourself you did not receive any such message, and save yourself a lot of trouble. Hearing voices in your head is not a good 'gift' to have in nowadays society.
If prophets do receive prophecy this way, then where would the brain start and the message end? Or in other words, how would the prophet transform and interpret the message before it gets out of his mouth? How reliable is the reproduction of such a communication (Chinese whisper effect?).
It is likely that a message gets altered before it is past on. It might come down to how good is the prophet in not adding, distracting or transforming the message before it gets recorded. It might turn out to be very hard to do that and reproduce a message exactly as it was originally meant to be.
