Jesus' second coming is going to be Him personally waging war against the entire world.

Why is Your apparel red,

And Your garments like one who treads in the wine press?

I have trodden the wine trough alone,

And from the peoples there was no one with Me.

I also trod them in My anger

And trampled them in My wrath;

And their lifeblood is sprinkled on My garments,

And I stained all My clothes.

For the day of vengeance was in My heart,

And My year of redemption has come.

I looked, but there was no one to help,

And I was astonished and there was no one to uphold;

So My own arm brought salvation to Me,

And My wrath upheld Me.

I trampled down the peoples in My anger

And made them drunk with My wrath,

And I poured out their lifeblood on the earth.

-- Isaiah 63:3-6

If the first Jesus was a mild mannered carpenter, the second Jesus is more like a warlord.
