That's according to the organisation, Christian Women Under Pressure for their Faith, which recently held an international conference in Belgium.
Activists from 23 nations heard the call of support for the growing problem of persecution facing Christian women.
According to the charity, 215 million Christians experience high, very high or extreme persecution in more than 50 countries.
The conference organiser, Kate Ward, said that women suffer disproportionally.
She said: "Women make up more than half the church. They are doubly vulnerable to discrimination and violence. Yet, all too often, their voices are not heard. They are silent."
Speaking through a translator, Mrs Haeyoung Park told the summit of a Christian woman caught praying in a North Korean prison.
"A prisoner reported to the guard that she was praying. So the guard took her to the investigation room and tortured her,' said Mrs Park.
"They hanged her upside down, burnt her with fire, cut her legs and beat her. And that's how she died."
The conference also addressed young girls being abducted in Egypt and Pakistan and being forced to convert to Islam.
The director of Christians' True Spirit, Katherine Sapna, gave an example of the suffering.
She said: "Twelve-year-old Naina from Lahore was abducted by Muslims because she was a Christian.
"She was held for six months, gang-raped by four men and tortured severely. She was burnt in the body and her sensitive body parts were damaged. She had two abortions because of the rape."
Attendees were urged to encourage women who have experienced persecution to speak out so they can start the healing process.
