Most of the world is unaffected by what you call a powerful prediction.
That's the best example of a self-fulfilling biblical prophecy that we have.
Let me show you what a compelling prophecy would look like. It's fiction of course - from the movie "Frequency."
Dennis Quaid's character's son, who is communicating to him by ham radio from his father future, wants to convince his father that it is really him and really coming from the future. From 1998, he tells his father who is living in 1969 at the time, the outcome of game five of the 1969 World Series by radio, which his father is watching live in a bar :
"Well, game five was the big one. It turned in the bottom of the 6th. We were down 3-0. Cleon Jones gets hit on the foot - left a scuff mark on the ball. Clendenon comes up. The count goes to 2 and 2. High fastball. He nailed it. Weis slammed a solo shot in the 7th to tie. Jones and Swoboda scored in the 8th. We won, Pop."
The father sees it happening live on TV, and becomes convinced. That's high quality prophecy.
The specificity and unlikeliness tell you it's not a parlor trick as long as you can be sure that the game you are watching is live.
High quality prophecy is specific - that is, detailed and unambiguous. The highest quality prophecy specifies the time and place. It needs to prophecy something surprising, something unlikely or unique, something that could not have been contrived, and was not self-fulfilling.
And the prophecies need to be verified, fulfilled completely, predict something that definitely occurred subsequently, and be unaccompanied by failed prophecies.
Nothing in this world can actually do that except science.
How about a standing ovation for the scientists at CERN that found the Higgs particle? The scientific prophets told us EXACTLY where to look (at what energy and under what conditions) and EXACTLY what we would find there (the particle's mass, charge, spin, and parity).
The physicists said, "Examine matter at that very high energy, and if we're right about reality, you'll find Higgs."
The scientists already had an excellent record of prophecy:
[1] Einstein prophesied the bending of light grazing past the sun. Such was the confidence in the priests of science that a fleet of ships was sent to various locations around the world to confirm the prophecy in 1919. It made headlines.

[2] Twenty-five years later, the scientists did it again. "Quantum electrodynamics (QED) is the study of how electrons and photons interact ... The predictions of QED regarding the scattering of photons and electrons are accurate to eleven decimal places."

[3] You can read about the prophecy of the cosmic microwave background and see the same thing. The priests of science predicted the existence of previously unsuspected radiation pervading the universe in an incredibly uniform way, and predicted it's precise temperature and wavelength, also later confirmed

So, based on that excellent reputation of prophecy, billions were allocated to look for the Higgs particle, with which the scientists built a fine machine - CERN's Large Hadron Collider - to look where man had never looked before except in his rich imagination.
[4] And lo and behold! A particle was born. Higgs! The scientific prophets were correct again. Biblical prophecy just can't compete with that.
Carl Sagan said it well:
"Think of how many religions attempt to validate themselves with prophecy. Think of how many people rely on these prophecies, however vague, however unfulfilled, to support or prop up their beliefs. Yet has there ever been a religion with the prophetic accuracy and reliability of science?"
