Song or music video: "Mercy" - Bad Omens

Listen/watch link: YouTube link

Lyrics:

When we fade into nothing, when we go up in the smoke
We'll beg God for a mercy that He knows we'd never show

If God came down from His kingdom, He came down from His home
And we asked Him if He'd take us back, He would surely tell us no

Additional prompt: No specific prompt, but I'd be interested no matter who the 'god' named in the song is! Any real life or made up religion! Or cult?

Warnings: Some swear words
