Jacquie Hagler of Lake City said she was hosting a group of 14 women at her house Friday for a jewelry party when the gunman, who had a bandana across his face, entered the home and ordered the women to hand over their money and phones, WJXT-TV, Jacksonville, Fla., reported Monday.
Police said one woman believed the incident to be a gag and said the weapon was a "water gun," leading the robber to put the gun to her head and threaten to "shoot someone."
Hagler said she decided her faith was the answer.
"When I realized what was going on, I stood up and said, 'In the name of Jesus, get out of my house now.' And he said, 'I'm going to shoot someone.' And I said it again, real boldly," Hagler said. "Everybody started chanting, 'Jesus, Jesus, Jesus,' and he did a quick scan of the room, and ran out the door as fast as he could go."
Police said they arrested Derek Lee, 24, on suspicion of home invasion robbery. He was being held in lieu of $200,000 bond.
Investigators said they are investigating whether Lee was also involved in an attempted robbery at a nearby ATM moments prior to the incident at Hagler's home.
