The Lord Said: "It's Going to Be Crazy"

Jeremiah 25:15 Thus the Lord, the God of Israel, said to me: “Take from my hand this cup of the wine of wrath, and make all the nations to whom I send you drink it. 16 They shall drink and stagger and be crazed because of the sword that I am sending among them.” 17 So I took the cup from the Lord's hand, and made all the nations to whom the Lord sent me drink it:... 

30“‘The Lord will roar from on high,
    and from his holy habitation utter his voice;
he will roar mightily against his fold,
    and shout, like those who tread grapes,
    against all the inhabitants of the earth.
31 The clamor will resound to the ends of the earth,
    for the Lord has an indictment against the nations;
he is entering into judgment with all flesh,
    and the wicked he will put to the sword,
declares the Lord.’

In this prophecy God shows Jeremiah beyond the exile to judgment on all the nations of the world, including Babylon. The "sword" of war will fill the earth; it will consume all nations. God will show himself to be the true Lion who roars and brings about righteousness.
