LAWRENCE COUNTY, Ky. (WSAZ) -- A knock on the door late at night is enough to cause anyone concern, but what if the man at the door claims to have a higher calling?

"In the Bible, it says beware of false prophets," Glenn Adkins said.

Glenn and his wife Brenda were getting ready for bed last Monday night when about 10:30, they heard a knock at the door.

"I just opened the door,” Glenn said. “It was a young man about 25, 30-years-old."

The man was holding a Bible. He told Glenn the lord had put it on his heart to come there and asked if he could come in and pray.

"We didn't know what to think about it, somebody coming so late at night," Glenn said.

"I can't see a Christian knocking on a door at 10 at night,” Brenda said. “They would know it would scare somebody."

Glenn says the man kept trying to talk his way inside their home on Bear Creek Road, and Glenn finally shut the door on him.

The couple wanted to alert their neighbors and posted about the visit on Facebook, where they found out others near the Boyd/Lawrence County line have had similar late-night encounters.

Tammy Gibson from Durbin says the following night, she heard voices outside her home, and someone knocked on her door about 10:30. She says she was too afraid to answer, and whoever knocked went away.

Glenn suspects the man may be trying to scope out homes looking for something to steal.

"You don't know if he was wanting see what kind of TVs, medication, or computers they want to steal to pay for a drug habit," Glenn said.

The Adkins have now installed new locks and security cameras.

The couple told the man he was welcome to come back and pray the next day at a decent hour, but he never showed up.

The Boyd Sheriff's Department is looking into this situation.
