Bobbi Kristina Brown's Family Holds Public Vigil

Feb. 9, 2015— -- Bobbi Kristina Brown's family is still praying for a miracle, and several hundred people gathered Monday for a vigil with that goal in mind.

The "Shining a Light for Healing" vigil began at 7 p.m. at the Amphitheater at Riverdale Town Center in Riverdale, Georgia, just outside of Atlanta, and was open to the public.

People held flashlights but attempts at lighting candles didn't work because it was too windy. A small stage held Brown family members. Bishop Donald Battle began the session, which included gospel songs, prayers, scripture, and a call for healing.

A vocalist who didn't give his name took the stage and performed "I Need You Now," Smokie Norful's soulful song calling for God's help. The crowd sang along, many raising their hands up in the air in prayer.

"It ain't over til God says it's over," Gwen Battle told the crowd.

"She thanks all of yall for your support. ""Continue to pray for us all as a people. ""We all should pray for each other. "

As of last Friday, Brown remained on life support after being found unresponsive, face-down in a bathtub last weekend. Brown, 21, the only child of the late Whitney Houston and singer Bobby Brown, was rushed to North Fulton Hospital in Roswell, where she had been treated, but sources have told ABC News that she has since been moved to the Neurology Intensive Care Unit of Emory University Hospital.

The Houston family last week released a statement about Brown's condition.

“Bobbi Kristina is fighting for her life and is surrounded by immediate family," the Houston family said in a statement. "As her father already stated, we are asking you to honor our request for privacy during this difficult time. Thank you for your prayers, well wishes, and we greatly appreciate your continued support."

Brown's cousin also asked for privacy.

"Let the detectives do their jobs," Jerod Brown told E! News last week, referring to the police investigation underway. "We all want to know what happened right now. We'd like to know what's going on."
