The following chart is the work of Paul Grevas. Many of us have heard of the blood moon tetrad of 2014-2015. Each of the full lunar eclipses fall on a Biblical feast day. Paul Grevas studied all of the previous biblical tetrads (tetrads are simply four full lunar eclipses in a row. Biblical tetrads fall on Passover and Tabernacles) and found that this one is completely unique. The eclipses from 2010 to 2019 are all symmetrical around a midpoint. That's never happened before. I didn't do the math for every one, but the ones I did check are symmetrical within minutes, literally. If you want to check them for yourself, you need to use the time of greatest eclipse, not just the date.
This is just one of several charts on his site. I encourage you to visit and read what he has to say: http://bloodmoonscoming.com/
So, what does it mean? At the very least, these are "signs in the sun and the moon." God wants us to pay attention. The Bible says there will be these signs as the end approaches:
Luke 21: 25-26 There
will be signs in the sun, moon and stars. On the earth, nations will be
in anguish and perplexity at the roaring and tossing of the sea. People will faint from terror, apprehensive of what is coming on the world, for the heavenly bodies will be shaken.
If you study the chart, you'll see that the time from the first blood moon to the midpoint and from the last blood moon to the midpoint is 266 days. That is the average length of a human pregnancy. If you know your Bible prophecy, that should ring a bunch of bells. God uses that kind of terminology in referring to end times.
Please note that this chart does not predict anything. It is simply recording the eclipses and showing that they are exactly symmetrical. What does it mean? We won't know until it happens. It certainly is God saying, "Pay attention. Be ready." He tells us to watch and be ready for Jesus' coming. Is this chart telling us that Jesus is coming? Maybe. Is it going to be in the time period of the chart? Maybe. Maybe not.
In my opinion, it means that Jesus' coming is "at the door." But, read your Bible and pay attention to what's going on in the world, and you'll come to the same conclusion. For me, the chart just confirms it.
Is that a reason to be afraid??? Only if you're not ready. Many years ago, I went to a Lutheran church for the first time and heard a sermon on the "end of the world." It made a huge impact on me - not so much for what was said about it, but just the whole idea. The "end of the world" really was coming - it wasn't just a science fiction thing. I couldn't get the idea out of my mind. I knew I wasn't ready. I considered myself a Christian at the time, but I barely knew what that meant. I started taking it very seriously, and not long after, read the Bible from cover to cover for the first time. I finally understood what it meant to be a Christian. It wasn't what you do, it's what you believe. Like Paul says in 1 Corinthians, it means believing that Jesus completely paid for my sins:
1 Corinthians 15:2-4 By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain.
For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures.
If you are trusting in Jesus as your savior, you have no reason to be afraid when these things start to happen. On the contrary, the Bible says.
Luke 21:28 When these things begin to take place, stand up and lift up your heads, because your redemption is drawing near.
