Why we have wars   Part 2

In Isaiah chapter 14, God's rebuke of Satan.

How you have fallen from heaven, O morning star, son of the dawn.

You have been cast down to earth, you who laid low the nations.

     You said in your heart, I will ascend to heaven. 

     I will raise my throne above the stars of God. 

     I will sit enthroned on the utmost heights of the sacred mountain. 

     I will ascend above the tops of the clouds. 

     I will make myself like the Most High. 

But you are brought down to the grave, to the depths of the pit.

Is this the man who shook the earth and made kingdoms tremble? 

The man who made the world a desert, who overthrew its cities? 

You are cast out of your tomb like a rejected branch.

Satan's last war 

He will be imprisoned during the Millenium, then released to march across the earth, attempting war on Israel. Fire from heaven will stop him, and he will be thrown into "the lake of burning sulfur with the beast and false prophet, tormented forever and ever." - Revelation 20:7-10
