The description we have seen so far in Revelation is beyond anything we could imagine or get or mind around; however, there is more to come during this period that apparently surpasses what we have heard so far. Fortunately, or unfortunately, depending on how you look at it; we are not told what is next in God’s plan immediately following what was described in chapter 9. Whatever it may be is so horrific that John is told not to even write it down.
Revelation 10:4 Now when the seven thunders uttered their voices, I was about to write; but I heard a voice from heaven saying to me, "Seal up the things which the seven thunders uttered, and do not write them."
One thing we do know is that God (at this point in the Tribulation Period) is still giving people the opportunity to repent. However, their hardened hearts and lust of the flesh has murder, drugs, sexual immorality and theft running rampant.
Revelation 9:21 And they did not repent of their murders or their sorceries or their sexual immorality or their thefts.
If you thought these things were rampant today, imagine how intense it will be in a world of people seeing the Wrath of God poured out and they still refusing to repent. It seems that although God’s Goodness leads many to repentance today (just as His Word says); in this period there will be an entire population of people that did not repent in light of God’s goodness, and they will not repent in view of God’s Wrath. When they realize the finality of their eternal torment in hell they will be without excuse which is why I think the Bible talks about “gnashing of teeth”. I liken it to doing something that was out of stupidity and was completely your fault….you can’t point the finger or complain….all you can do is grind your teeth in hopelessness.
Matthew 8:12 But the sons of the kingdom will be cast out into outer darkness. There will be weeping and gnashing of teeth."
Luke 13:27-30 But He will say, 'I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.' 28 There will be weeping and gnashing of teeth, when you see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, and yourselves thrust out. 29 They will come from the east and the west, from the north and the south, and sit down in the kingdom of God. 30 And indeed there are last who will be first, and there are first who will be last."
