As I mentioned earlier and/or on other threads, the eclipses by themselves causing things to happen, I agree. I think what the eclipses do accomplish is to point people to the feasts of Yahweh, and to consider end time prophecy. I don't seriously believe these are the eclipses in Joel for "the Day of the Lord". When that day comes, we will surely know, and in addition, an eclipse if not really required for a blood moon anyway. The atmospheric conditions from tribulation can accomplish that nicely. Not saying that's what will happen specifically, just sayin' that this is another way.
Certainly God knew ahead of time when these eclipses would occur, and were foreordained to warn us of end times, like setting the alarm clock to wake us up. And alarm clock isn't the reason we get up --- it's a sign for us to get up. But the action isn't because of the clock.
I have not doubt that times are more perilous than ever, and it's augmenting to that Day. If the blood moons did nothing else, at least it has people looking more at the biblical calendar, the feasts and prophecy of the end. To that end, I think just doing that the eclipses have/and will fulfill their functions.
