SAN ANTONIO -- The Book of Genesis says God uses the sun, moon, and stars for signs and seasons. Examples can be found throughout the Bible.
Think of how a star led the wise men to Jesus or how the sun stood still as Joshua led Israel to victory over its enemies.
According to Pastor John Hagee, God is getting ready to speak this way once again.
"There's a sense in the world that things are changing and God is trying to communicate with us in a supernatural way," Hagee told CBN News.
"I believe that in these next two years, we're going to see something dramatic happen in the Middle East involving Israel that will change the course of history in the Middle East and impact the whole world," he predicted.
Four Blood Moons
In his latest book, Four Blood Moons: Something Is About to Change, Hagee lays out what he calls celestial signals. He describes how a series of blood moons in 2014 and 2015 will have great significance for Israel.
Although single blood moons happen fairly regularly, four appearing so closely together is extremely rare. There have only been a series of blood moons a handful of times over the past 500 years.
So what exactly is a blood moon and what is the biblical significance?
"A blood moon is when the Earth comes between the sun and the moon," Hagee explained. "And the sun is shining through the atmosphere of the Earth and casts up on the moon a red shadow. And so the moon appears to be red."

Such moons appear several times in scripture.
In the book of Joel, God says there will be "wonders in the heavens and in the earth, blood, and fire…the sun will be turned to darkness and the moon to blood before the coming of the great and dreadful day of the Lord."
In Acts, the Apostle Peter repeats that verse from Joel. And the book of Revelation says that during the Great Tribulation, "the moon will become like blood."
Blood moons are set to appear in April 2014, on Passover, and then again in October 2014 during the Feast of Tabernacles, or Sukkot.
The timing is the same for 2015 -- a total of four blood moons, all appearing on Jewish feast days.
"The sun and the moon and the Earth are controlled by God almighty," Hagee said. "He is the one that is getting them in a direct alignment on a certain day at a certain time -- but each time, it's a Passover or Sukkot.
In the past, the rare appearance of four blood moons on these feast days has coincided with major events for Israel and the Jewish people.
In 1492, Spain expelled the Jews. Columbus also discovered America, which became a safe haven for the Jewish people.
"In each of these blood moons, you have something that begins in tragedy and ends in triumph," Hagee explained.
For instance, in 1948, Israel was reborn as a nation.
"After 2,000 years, God supernaturally brought them from 66 nations and a nation was born in a day," Hagee noted. "That again was a supernatural something that happened following the tragedy of the Holocaust."
In 1967, Israel won the Six-Day War and recaptured Jerusalem.
"For the first time in 2,000 years, Jerusalem and the State of Israel were together again," Hagee said.
Two blood moons have already appeared in 2014 and they coincided with major events in the Middle East and the world:
- A war between Israel and Hamas in the summer of 2014
- The rise of ISIS and the emergence of a new caliphate in Syria and Iraq
- Terrorism increasing around the world
- And anti-Semitism on the march in Europe
Then, there are continued attempts by the world to strike a deal with Iran, which promise to only increase in 2015.
"The only reason that Iran will not acquire a nuclear bomb will be that Israel chooses a military solution to that crisis," Hagee told CBN News.
"I believe that if that happens, it will start a series of events that will change the course of world history," he said. "If Israel does not, then it will still change the course of world history."
Hagee has been warning of the Iranian nuclear threat through his work with Christians United for Israel, which he founded in 2006. It is now the largest pro-Israel organization in America, with some 1.3 million members.
He holds nights to honor Israel across the country and at San Antonio's Cornerstone Church, where he serves as senior pastor. The first event, in 1981, drew bomb threats and vandalism from anti-Semites.
Yet Hagee continues his mission.
"If there was ever a time for the Christians of America to stiffen their spine and stand up and speak up, it's now," Hagee admonished. "To see evil and not call it evil is evil. Not to speak is to speak. We cannot be silent and receive God's approval at a time like this."
He said it's still unclear what the coming blood moons will bring, but he is certain of one thing.
"When all is said and done, the flag of Israel will be flying over the walls of the city of Jerusalem when Messiah comes, and it's going to be forever," he said. "And every nation that rises up in judgment against Israel God will punish and punish severely."
