The "I Don't Care" singer posted two guided prayers on his social media late Thursday evening and told fans "they have really been helping me."
As The Blast reported, the 25-year-old underwent treatment for depression earlier this year and church has become a staple in the Bieber household.
"Here’s a guided prayer. When you have a quiet moment get into a comfortable position and listen," he advised his followers. "They have really been helping me and thought I would share."
Bieber's famous friends are leaving comments on his post.
Pratt, who's a religious man himself, was one of the first celebrities to send his support.
"I LOVE THIS. THANK YOU DO MUCH WHAT AN AMAZING WAY TO USE THIS PLATFORM. WAY TO GO JB WAY TO GO JUDAH," the actor wrote and added, "Best 6 minutes of my day."
Pratt and Bieber have long been followers of the same Hillsong church.
Pratt may have been the first, but there's a long list of famous friends who left Bieber some love.
"That's So Raven" star Kyle Massey wrote, "I hope everyone is listening to this entire thing like I am. This is powerful."
His pastor friend Rodney Lavoie Jr. told Bieber "you're not alone," while the singer's Dogpound trainer, Saint Yeti, commented with several heart and volcano emojis.
Bieber's recently opened up about his past struggles, which included drug abuse at an early age.
Airing out his dirty laundry, the singer said he "became a shell of a person" after he started "doing pretty heavy drugs at 19" and "abused all his relationships."
He said it made him "resentful, disrespectful to women, and angry." Justin added it took years for him to mend the relationships he had destroyed and he credited his marriage to Hailey for helping him be better.
