Pattie Mallette, mom of singer Justin Bieber and a bestselling author, is asking the Holy Spirit to reach out and enlighten her son.  The look to God for help is timely as a video appeared to show him fighting on the night of the NBA Finals in Cleveland, Ohio.

"Holy Spirit come and teach us each who you are. Amen," Mallette posted on Twitter alongside a graphic of her son. The post has been retweeted more than 9,000 times and liked by over 13,000 users.

The video, obtained by TMZ, was supposedly taken at the lobby of the hotel where Bieber was staying in Cleveland. It appeared to show Bieber and a man fighting. No charges were pressed.

Last March 1, Bieber celebrated his 22nd birthday and Mallette posted a prayer on Twitter.

"22 years ago I was 18yrs old, pregnant & scared. But God. Lord encounter @justinbieber for his bday! Give him all I couldn't, in Jesus name," she wrote.

For the past two years, Bieber has been in the limelight over his behaviour.

In 2014, he was accused of assaulting a limousine driver, egging his neighbour's house and ended up paying $80,000 in fines, and getting caught for DUI in Miami.

Bieber told Billboard last year that it was his mother who introduced him to music and religion.

"When I was 7, she wouldn't let me listen to anything but [Pastor] Judah [Smith]'s tapes falling asleep," he said.

Bieber said in the last two years, his relationship with his mom was "pretty nonexisting."

"I was distant because I was ashamed. I never wanted my mom to be disappointed in me and I knew she was. We spent some time not talking, so it takes time to rebuild that trust. She's living in Hawaii now, so it's hard, but getting better. She's an amazing woman and I love her," he said.

When he was 19, Bieber reconnected with Pastor Smith, of City Church in Seattle, Washington.

"I'd come and listen to him and try to hear him out. I had all these questions and things were not adding up. 'Well, why is this, then? How did all those animals fit on Noah's Ark, then?'" he said, adding that he now understands faith.

"That's what it's all about—not questioning it," the Canadian star said.

Smith previously said, "We text almost daily, and it's not just me sending him Bible verses anymore. He'll send them to me, along with encouraging thoughts or an encouraging emoticon. I'm committed to helping him and protecting him, but it's fair to say we're there for each other."
