As the article below sums it up, "Clearly, the scriptures that Pastor Hagee says refer to red moons are not the result of lunar eclipses. Instead, these verses describe cosmic phenomena that tell of the moon turning red or being darkened because of comets falling and putting so much dust into the atmosphere that even the sun will be darkened. These verses tell of impact events that are to take place in the last stages of the Tribulation Period as described in the Fifth, Sixth, and Seventh Trumpet, and the Seventh Vial of the Book of Revelation. (Also, see Isaiah 13:5-13 and Isaiah 34:4)."
Keep reading the link below to see exactly why the four blood moons may be astronomically interesting, but in no way are prophetically interesting, nor are they related to any prophecy of the bible. (Correctly interpreted prophecy of the bible, that is).
Four Blood Moons
"Bottom line: the four blood red moons caused by solar eclipse that are to occur in 2014-2015 do not constitute signs of important prophetic events that will soon take place."
