The 31-year-old pop star has taken to social media to open up about his faith, revealing that he "wouldn't be able" to get through the day without love from Jesus.
Bieber - who is married to model Hailey Bieber - wrote on Instagram: "grateful for a new day.
"grateful for Jesus
"he meets me every morning with forgiveness and love
"that I truly don't deserveÂ
"so grateful that he gives this love so freely, so graciously
"Wouldn't be able to get thru the day without his love.
"It meets me at my lowest. (sic)"
Bieber's post featured a selfie of the pop star wearing a Toronto Maple Leafs jacket while looking into the camera.
The chart-topping singer also shared a screenshot of the post on his Instagram Stories, alongside Lord Do It For Me by Zacadi Cortez.
Bieber has been married to Hailey since 2018, but speculation has swirled in recent months about the status of their relationship.
Despite this, he insisted earlier this year that marrying Hailey is the one of the "smartest" decisions he's ever made.
The pop star - who previously dated Selena Gomez - told Vogue magazine: "I've done a lot of dumb things in my life, but the smartest thing I've ever done was marry Hailey."
Bieber also pushed back against the online criticism that Hailey often faces.
He said: "She's in the spotlight, and has the attention because of her effortless knack for style, business, art and fashion. And the way she makes being a mom and wife look easy."
Hailey, 28, has previously made concerted efforts to "correct" the online narrative. However, she's found those efforts to be futile and she's now learning from her husband's approach to life.
The model - who has enjoyed huge success with her Rhode skincare brand - shared: "I've learned so much from Justin, really.
"He's been doing this literally since he was a child and he has had to face the most scrutiny of any person that I know. He was like, 'Baby, trust me, I've been here before many, many times. You're not going to win. There is no winning.'"
