True fire
But seriously in some versions of the Bible, such as King James, the verse continues past saying amen. And because the Bible was originally in Hebrew and the Hebrew language is weird to say the least, having no vowels or spaces, and translations can be awkward, so there’s conflicting evidence to suggest that John did actually write Amen as the last word. Most likely it was widely agreed upon that putting Amen at the end of Revelation was a choice made by the church to end off the Bible. It fits with John’s writing, the book ends with a prayer, but he didn’t specifically say Amen so likely the church filled that in so this meme is inaccurate.
Still, fire.
