God is a God of prophecy (Revelation 19:10). In fact, roughly two-thirds of God's word is related to it. The Bible is the only book in the world ever written that can demonstrate its inspiration is supernatural and that it is from a Being Who exists outside this physical realm of time and space.
Prophecy is simply history written in advance of the actual event. Its fulfillment is a major proof of God's existence - and more. It attests to his authority and power to influence people's lives and foreordain the course of events here on planet earth. God not only gives prophecies in the Bible on what will happen in the future, he has the ability to cause his predictions to come to pass in every detail within a specified time frame.
Scoffers of prophecy and its claim of divine origination may state that fulfilled prophecies are nothing more than lucky guesses. Attributing successful long-term Biblical predictions (sometimes spanning several centuries or millennia) to guesswork and luck, however, is preposterous. The divine spiritual origin of prophecy means that the moral standards of the Bible, such as on sexual morality, should not be lightly dismissed. The God who destroyed the cities of Sodom and Gomorrah, and who predicted the destruction of Babylon and Nineveh, is very much alive and well.
Although the world today laughs at prophecy and the thought of a wrathful God who punishes nations for their sins, the ruins of cities scattered throughout the Middle East bear record otherwise. The God of love (1John 4:16), shown perfectly by his willingness to sacrifice His Son's life for us (1John 3:16), is the same God that hates sin. He demands that we repent of breaking His holy law (2Peter 3:9; Romans 6:12-16; 8:4). As the book of Revelation proclaims, the unrepentant during the Second Coming of Jesus will meet the same prophetic Biblical fate as ancient Babylon, Assyria and Egypt.
