Pastor John Hagee is warning members of his megachurch to prepare for the end of the world because a "blood moon" eclipse on Tuesday is signaling that the End Times could be beginning.

On Tuesday, most of the United States will be treated to the first of four complete lunar eclipses -- which scientists call a tetrad -- occurring in six month intervals. The eclipses are often referred to as "blood moons" because as sunlight shines on the moon through the Earth's atmosphere, it gives the moon a red color.

Hagee, pastor of Texas' Cornerstone Church, has written a book on the phenomenon titled Blood Moons: Something is About to Change. And he is airing a live television event on Tuesday to reveal "direct connections between four upcoming blood-moon eclipses and what they portend for Israel and all of humankind."

"Is this the end of the age?" Hagee asked during a recent sermon, before quoting Acts 2:19-20: And I will show wonders in Heaven above and signs in the Earth beneath, the sun shall be turned into darkness and the moon into blood before the coming of the great and awesome day of the Lord."

"I believe that the heavens are God's billboard, that he has been sending signals to planet Earth," he explained. "God is literally screaming at the world, 'I'm coming soon.'"

Hagee predicted that the four eclipses were signaling a "world-shaking event that will happen between April 2014 and October 2015."

"God sends plant Earth a signal that something big is about to happen! He's controlling the Sun and the moon right now to send our generation a signal, but the question is, are we getting it?"
