Will Christ Do All of the Fighting Or Will We Have a Part? Battle of Armageddon. Revelation 19:21 -- And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh. Will HE do all of the fighting or will we have a part in it too? After HE comes down and has destroyed the rebelling armies at Armageddon, where does HE walk on this earth? What does HE do after that? What does GOD do beyond the Battle of Armageddon?
