Four Blood Moons? What's next?

Tonight I would just like to explain a little about the Moons turning to blood.  There is a scientific explanation of course.
But there is also a spiritual explanation.  

Four Blood moons do not occur often in history.  In the past 500 years it has only occurred 3 times.  And this year 2014-2015 it is the 4th time.
From John Hagee's book:

"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

1. Passover-April 15, 2014
2. Feast of Tabernacles-October 8, 2014
3. Passover-April 4, 2015
4. Feast of Tabernacles-September 28, 2015

In the Bible there are only three prophetic instances recorded:

Joel 2:31 "The sun shall be turned into darkness and the moon into blood before the great and terrible day of the Lord come."

Acts 2:20 "The sun shall be turned into darkness and the moon into blood, before that great and terrible day of the Lord come."

Revelation 6:12 "And I behld when he had opened the sixth seal, and lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood; and the stars of heaven fell unto the earth, and the heaven departed as a scroll when it is rolled together, and every mountain and island were moved out of their places."
