God is alerting believers of the soon return of His Son through what are called "signs of the times." These are prophecies concerning world events that we are told to watch for, prophecies that will identify the season of the Lord's return.
The Bible is full of these signs. There are about 500 prophecies in the Old Testament that relate to the Second Coming of the Messiah. In the New Testament, one out of every 25 verses is concerned with the return of Jesus.
In fact, there are so many signs that it is difficult to grasp all of them. The best way I have found to do this is to put them in categories:
1) The Signs of Nature — We are told to watch for earthquakes, famine, pestilence, and signs in the heavens (see Matthew 24:7 and Luke 21:11).
This is the least respected category of signs for several reasons. For one thing, many people simply shrug their shoulders and say, "There have always been natural calamities, so what else is new?" Note that Jesus says these signs will be like "birth pangs" (Matthew 24:8) — that is, they will increase in frequency and intensity as the time draws near for His return. In other words, there will be more intense earthquakes and more frequent ones. That is exactly what is happening today.
Another reason these signs are given little respect is because most Christians are so rationalistic that they do not really believe in the supernatural, and they therefore find it difficult to believe that God speaks to the world through signs of nature. Yet, the Bible teaches this principle from start to finish.
God dealt with the world's sin through a great flood in the days of Noah (Genesis 6). He called the nation of Judah to repentance through a terrible locust invasion (Joel 1). In like manner, He called for the nation of Israel to repent by sending drought, wind storms, mildew, locusts, famine and pestilence (Amos 4:6-10). The prophet Haggai pointed to a drought as evidence that God was calling the people to get their priorities in order (Haggai 1:10-11).
The New Testament begins with a special light in the heavens marking the birth of the Messiah (Matthew 2:2). On the day that Jesus was crucified, there was three hours of darkness and an earthquake (Matthew 27:45-51). And when Jesus returns, the earth will experience the greatest earthquake in its history as every mountain is lowered, every valley is raised, and every island is moved (Revelation 16:17-21).
God has always spoken through signs of nature, and He continues to do so today. We had better pay close attention to them.
2) The Signs of Society — Jesus said that society will become increasingly lawless and immoral as the time approaches for His return. In fact, He said it would become as evil as it was in the days of Noah (Matthew 24:12,37-39).
Paul paints a chilling picture of end time society in 2 Timothy 3:1-5. He says it will be characterized by three loves — the love of self (Humanism), the love of money (Materialism), and the love of pleasure (Hedonism). He then points out that the payoff of this carnal lifestyle will be what the philosophers call Nihilism — that is, a society wallowing in despair. Men's minds will become depraved (Romans 1:28), and people will call evil good and good evil (Isaiah 5:20).
We are seeing these prophecies fulfilled before our eyes today as we watch our society reject its Christian heritage and descend into a hellish pit of lawlessness, immorality, and despair. Even worse, we are exporting our nihilism around the world through our immoral and violent movies and television programs.
3) The Spiritual Signs — There are both positive and negative spiritual signs that we are to watch for. The negative ones include the appearance of false christs and their cults (Matthew 24:5,11,24), the apostasy of the professing church (2 Thessalonians 2:3), an outbreak of Satanism (1 Timothy 4:1), and the persecution of faithful Christians (Matthew 24:9).
These negative spiritual signs began to appear in the mid-19th Century when Christian cults started forming. First came the Mormons, then the Jehovah's Witnesses, and then a great variety of spiritualist groups like the Church of Christ Scientists and the Unity Church.
The apostasy of the mainline Christian denominations began in the 1920's when the German school of higher criticism invaded American seminaries and undermined the authority of the Scriptures, teaching that the Bible is Man's search for God rather than God's revelation to Man.
During the 1960's Satanism exploded on the American scene and has since been exported worldwide through American movies, books, and television programs. Dabbling in the occult has become commonplace in the form of astrology, numerology, crystal gazing, transcendental meditation, and channeling. The whole trend has consummated in the appearance of the New Age Movement with its teaching that Man is God.
As society has secularized, true Christianity has come under increasing attack. Judeo-Christian values, once the foundation of Western Civilization, are now openly mocked, and those who still adhere to them are castigated as "intolerant fundamentalists" by the media.
The positive spiritual signs include the proclamation of the Gospel to the whole world (Matthew 24:14), a great outpouring of the Holy Spirit (Joel 2:28-32), and spiritual illumination to understand prophecies that have been "sealed up" until the end times (Daniel 12:4,9).
As with the negative signs, we are seeing these positive signs fulfilled in our day and time. Through the use of modern technology, the Gospel has been proclaimed throughout the world in this Century, and the Bible has been translated into all major languages.
The great end time pouring out of the Holy Spirit that was prophesied by the prophet Joel has also begun. Joel called it "the latter rain" (Joel 2:23), and he said it would occur after the Jews had returned to their land. The state of Israel was re-established in 1948. In 1949 God anointed two ministries that would have a worldwide impact — the ministries of Billy Graham and Oral Roberts. Then, in the 60's, came the Charismatic Movement which prompted renewal in worship and gave emphasis to the continuing validity of the gifts of the Spirit.
The acceleration in the understanding of Bible prophecy began in 1970 with the publication of Hal Lindsey's book, The Late Great Planet Earth. It seemed to open up to popular understanding many prophecies that had been "sealed up" until the end times (Daniel 12:4, 9). Remarkably, it became the number one best seller in the world — with the sole exception of the Bible — for the next ten years!
4) The Signs of Technology — The book of Daniel says that there will be an explosion of knowledge in the end times and that people will move about quickly (Daniel 12:4). There are many Bible prophecies that cannot be understood apart from modern technology. For example, how can the whole world look upon two bodies lying in the streets of Jerusalem (Revelation 11:8-9)? Modern television satellite technology makes it easy. How can the False Prophet build an image of the Anti-Christ that appears to be alive (Revelation 13:15)? The answer, of course, is the science of robotics. How can the False Prophet require all people on earth to take the mark of the Anti-Christ in order to buy and sell (Revelation 13:16-17)? It would not be possible apart from computers and lasers.
Jesus said that the Tribulation will be so terrible that all life on earth would cease to exist if He did not cut the period short (Matthew 24:21-22). How could all life be threatened prior to the advent of nuclear weapons? Another reference to nuclear power is likely contained in Luke's statement that men in the end times will "faint from fear" because "the powers of the heavens will be shaken" (Luke 21:26). That certainly sounds like a reference to the splitting of the atom.
5) The Signs of World Politics — The Bible prophesies that there will be a certain pattern of world politics that will characterize the end time geopolitical map.
The focus will be the re-established state of Israel (Zechariah 12:2-3). It will be besieged by a menacing nation from the "remote parts of the north," the nation of "Rosh" — or modern day Russia (Ezekiel 38:2,6). There will also be a threatening nation to the East that will be capable of sending an army of 200 million — namely, China (Revelation 9:13-16 and Revelation 16:12-13). A third source of danger to Israel will be the Arab nations that immediately surround it. They will covet the land and will try to take it from the Jews (Ezekiel 35:10 and 36:2).
Another key player on the world political scene in the end times will be a coalition of European nations that will form a confederation centered in the area of the old Roman empire (Daniel 2:41-44, Daniel 7:7,23-24, and Revelation 17:12-13). This confederation will serve as the political base for the rise of the Anti-Christ and the creation of his worldwide kingdom (Daniel 7:8).
Other international political signs include wars and rumors of wars (Matthew 24:6), civil wars (Matthew 24:7), and general international terrorism and lawlessness (Matthew 24:12).
6) The Signs of Israel — The signs related to the state of Israel are prolific and very important.
The most frequently repeated prophecy in the Old Testament is the prediction that the Jewish people will be regathered from the "four corners of the earth" in the end times (Isaiah 11:10-12). The Bible states that a consequence of this regathering will be the re-establishment of the state of Israel (Isaiah 66:7-8). The Scriptures say that once the Jews are back in their land, the land itself will experience a miracle of reclamation (Isaiah 35). The desert will bloom and people will exclaim, "This desolate land has become like the garden of Eden" (Ezekiel 36:35).
Another end time miracle will be the revival of the Hebrew language (Zephaniah 3:9). Most people are not aware of the fact that when the Jews were dispersed from their land in 70 A.D., they ceased to speak the Hebrew language. The Jews who settled in Europe developed a new language called Yiddish — a combination of German and Hebrew. The Jews who migrated to the Mediterranean basin created a language called Ladino — a combination of Hebrew and Spanish.
Other significant signs of Israel that we are told to watch for in the end times include the re-occupation of Jerusalem (Luke 21:24), the resurgence of Israeli military strength (Zechariah 12:6), and the re-focusing of world politics on Israel (Zechariah 12:3).
All these signs have been fulfilled in this century. The nation has been re-established, the land has been reclaimed, the ancient language has been revived, the Jews are back in Jerusalem, and Israel is the focal point of world politics.
Jesus says in Luke 21:28 that when these signs begin to happen, we should "straighten up and lift up our heads" because "our redemption is drawing near."
The Key Signs
The most important signs are the ones that relate to Israel because God uses the Jews throughout the Scriptures as His prophetic time clock. By this I mean that very often when the Lord is revealing an important event that will take place in the future, He will point to the Jewish people and state that when a certain thing happens to them, the important event will also occur.
A good example of this principle can be found in Daniel 9 in the famous "Seventy Weeks of Years" prophecy. The prophet tells us to watch for a decree to be issued that will authorize the rebuilding of Jerusalem. He then says that the Messiah will come sixty-nine weeks of years (483 years) after that decree is issued to the Jewish people.
There are two key prophecies which relate the return of Jesus to events that have occurred in Jewish history since 1948. These two events clearly established the period in which we are now living as the season of the Lord's return. http://lamblion.com/articles/articles_rapture1.php
