I had a moment of confusion when i didn’t catch the change in perspective, but that was just my reading – nicely done!

I agree with Mark, though your tense is perfect. Keep it that way and work on your transition.

It is a confusing perspective. It’s what Emilea is hearing, not us. She’s not the target either, he’s not talking to her, he’s essentially background noise. In that case, I would italicize.

“Someone soon will turn the world around with her words; will reset the calendars and chase the beasts out of Bethlehem! She will remind everyone that to be human is not a small thing, and that the universe and all of eternity are blank maps waiting for us to sketch something in!”

As a personal preference, try cutting the preachers speech off, street preachers don’t stop talking. Emilia could be on a bus, walking by, crossing a street, or she could be the street preachers wife?

_and that the universe and all of eternity are blank maps waiting for us to—”

Emelia smiled and ran a hand over the curve of her belly.

Edited! Thanks for the feedback!
