Before we get back to what's going to happen between the Antichrist and the Jewish people, it's probably a good time to talk about the cosmic disturbances that are going to hit the globe during the seven year Tribulation period. Actually it's never a good time to talk about that, because it's not going to be pretty. In fact it's going to be awful.
First of all the Bible predicts that there are going to be global wars, and in this day and age that can only mean one thing: nukes. There will undoubtedly be fallout as a result of bombs, and that of course will be horrible in itself. The Bible also describes large objects hitting the earth, and many people who have studied this sort of thing for a living see asteroids and/or meteorites as being the culprits. We know from watching the History Channel and Bruce Willis movies that one large asteroid could do us all in, but the Bible is clear that although these space invaders do a lot of damage, they don't end life on the planet for everyone. But yes, billions will die during the Tribulation, due in no small part to the cosmic disturbances.
The Bible predicts that some of the effects of these disturbances during the Tribulation are: the sun being darkened (possibly from ash and dirt flying up in the air, not to mention fires), the moon turning blood red (not sure what that means), the sea turning blood red (that has actually happened in some parts of the world), fish dying by the billions (and probably washing up on shore--yuk!), searing heat (global warming advocates will finally have their day), famine, diseases, plagues, and sky rocketing inflation, which obviously will be the least of anyone's worries.
After it gets done describing these horrific environmental catastrophies, the Bible makes it clear that many people on the earth still do not repent (which just means to change your mind) of the moral failings in their lives. It's as if to say, "what is it going to take to get you to turn from the evil that you are following, and follow God?"
Many reasons have been put forth as to why many of the people living on earth during this Tribulation period don't repent of their sins, even while the world is unraveling around them. One that makes sense to us is what is known as "Cultural Relativism." Relativism says that there are no rights and wrongs, that what is wrong for you may be OK for me. Relativism says "I've got to do what's right for me." It says, "anything I do is OK as long as I don't hurt anybody." Relativism says that what was wrong 20 years ago is probably OK now. Just look at how the standards have changed on TV and movies and you'll get the picture.
So, if I don't know that what I'm doing is morally wrong, then why would I think about changing? If I look at evil as good and good as evil, then it's actually impossible for me to turn my behavior around. Why would I? What we need is a standard, a standard by which to measure our behavior, a standard that can tell us right from wrong. We put forth that the Bible is that standard, and that without it, there is little hope of us changing our minds about our behavior, even when all the signs are there that we should.
Another thought on why some people in the Tribulation will not change their mind about their behavior is an even bleaker one..........for them it has become too late.
