I’m not sure of you’re just talking about one so-called Blood Moon, or the “tetrad”. If you’re just talking about one blood moon, then that may be a different matter than the tetrad.
With such tremendously apocalyptic events described in Revelation as:
astronomic judgments falling upon one third of the earth in trumpets one through four,
great earthquakes the like of which none on earth have ever seen (which would trigger major volcanic activity),
I rather doubt the sun darkened and moon turned to blood in Joel and Acts 2 is referring to mere eclipses.
Viewing the sun and moon on earth at the end of the great tribulation, through great volcanic clouds, the sun and moon would indeed look as so described in Joel and Acts 2.
But if we divorce these tetrad blood moons eclipse events from the Joel and Acts 2 "sun darkened moon turned to blood" day of the Lord prophecy, which is NOT a mere eclipse event, then, yes, I think they could very well be portents of something to happen in the near future.
The problem is, Blitz and Hagee do NOT divorce these passages of scripture, which can hardly be mere eclipses, from their tetrad blood moons theory. See my point? Like I said, something doesn't compute here.
