What will happen in the Righteous Gemstones series finale?

The synopsis of the episode, per Decider, reads: “A stroke of fate has left its mark on the Gemstone family. Together, they travel to Galilee Gulch. There, their faith is put to the ultimate test.”

HBO’s teaser for the episode shows family patriarch Eli (John Goodman), his brother-in-law Baby Billy (Walton Goggins) readying to reenact the crucifixion of Christ on his Teenjus TV show, and his kids Judy (Edi Patterson) and Jesse (Danny McBride) getting choked up.

“Saying goodbye is never easy,” late matriarch Aimee-Leigh (Jennifer Nettles) says via narration from beyond the grave. “Sometimes it’s easier to never say goodbye and just leave things where they lay. Even if we lose our way to each other, know I’ll always be waiting. I’m here whenever you need me.”
