For 2,000 years Jesus and His kingdom have remained unseen by this world, manifested only in the hearts and lives of those who love and receive Him by faith. But the day is coming when this present age will be over and all the world will "see the Son of Man coming in the clouds with power and great glory" (Matthew 24:29-31).
The Bible warns us that a powerful world government will arise in the final days of man's dominion on Earth, led by a demonic dictator—the Antichrist—who will be possessed by Satan. The last three and a half years of his rule will be a time that the Bible calls the "Great Tribulation" (Matthew 24:21; Revelation 7:14).
