China arrested 30 Christians. Some fear it's the start of a bigger crackdown

Last Friday Grace Jin Drexel received a text from her father in China, the prominent pastor Jin Mingri, telling her to pray for another pastor who had gone missing. The text said that the other pastor had been detained while visiting the southern city of Shenzhen."Shortly after that, I got a call from my mum. She said she couldn't contact my dad," Ms Jin Drexel, who lives in the US, told the BBC.
