Apocalyptic -- More Than Egypt!

1. Seven Last Plagues
2. Seven seals
3. Seven vials

he 7 Thunders reference 7 vile sins; These are God's Wrathful words.

So each thunder is like a peal. And the corresponding punishment, drills down to the Seven Vials. In descending order. God does not punish good behavior, He punishes sin.

Are the sins of men referencing the 7 Deadly Sin's or Capital Sins. The Lord said as knowledge increases so does the sins of men. So they evolve.

So, all these Seven Lasts are to punish sin. And you can read them in Apocalypse, and see how men are reacting. They are so into sin, that, they cannot see anything else, and even God's punishments don't seem to serve any purpose for evolved sinners. Which Jesus calls 'spiritually wicked'.

Peace be with you always
