The purpose of prophecy in the bible is given in Isaiah 46:9-10:
“I am God, and there is none like me, declaring the end from the beginning, and from ancient times the things that are not yet done.”
Supernatural predictions are evidence provided to us for verification.
Not a single prophecy from the Bible has been proven false. Many prophecies remain in the future, but all that have come to pass have been verified to be true. Thousand of prophecies from the Bible have been fulfilled.
An amazing prophecy is found in Revelation 11:9. In 90 A.D., the prediction was made that many nations would view the same event within a few days time. Today, billions of people from around the world simultaneously view the same event through mass communication. When the prediction was made, communication and transportation across the Roman Empire took months of time.
In 332 B.C., Alexander the Great conquered the island fortress of Tyre by building a causeway from the ruins of the old city. This fulfilled the prophecy in Ezekiel 26:4-5, written hundreds of years before. At the time of Ezekiel, Tyre was the capital of Phoenicia and the island fortress had not yet been built. Ezekiel predicted:
“They shall destroy the walls of Tyre, and break down her towers: I will also scrape her dust from her, and make her like the top of a rock. It shall be a place for the spreading of nets in the midst of the sea.”
Two hundred years later, Alexander scraped away everything, leaving bare rock.
And there are hundreds of fulfilled prophecies related to the birth, life, death and resurrection of Jesus Christ.
