“He would not ride in on a war horse and usher in a bloodbath.”
Biblically, Christ’s first act when He returns is to ride a white horse and slay all His enemies... It will be a very, very large bloodbath.
What makes you think it will be a bloodbath?
The final judgment talks about separating the sheep from the goats. The sheep go to heaven; the goats go to hell.
Or am I not understanding your post?
