Division is the Evidence Satan's Kingdom (the nations of this world) has Fallen!

Mark 3:24 And if a kingdom be divided against itself, that kingdom cannot stand.

25 And if a house be divided against itself, that house cannot stand.

26 And if Satan rise up against himself, and be divided, he cannot stand, but hath an end.

We're witnessing the fall of the kingdom of Satan (typified in the Bible by Babylon). The world has fallen! The world has fallen!

What does it mean that the world has fallen? It means that Christ has risen up and taken the kingdom of Satan and has begun to rule over the nations of the world:

Luke 4:5 And the devil, taking him up into an high mountain, shewed unto him all the kingdoms of the world in a moment of time.

6 And the devil said unto him, All this power will I give thee, and the glory of them: for that is delivered unto me; and to whomsoever I will I give it.

Compared to:

Revelation 11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.

The kingdoms of this world belong to Christ. He now rules the earth. And His throne is the throne of judgment – because He is ruling the earth, not for mankind's benefit, but in order to punish the inhabitants of the earth.

Revelation 19:15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
