With the Winter Olympics due to get underway in February, Christians are being urged to boycott the event over the religious freedom violations carried out by host nation China.
Despite the pandemic, the Games are expected to go ahead as normal with Beijing hosting.
However human rights groups have raised concern over the persecution carried out against religious minorities there.
US President Joe Biden has already introduced a diplomatic boycott with other nations, including the UK following.
Now, Christians are being urged to play their part in standing in solidarity with persecuted brothers and sisters in China.
Religious freedom charity Open Doors and Sam Brownback, a former US ambassador for religious freedom have united in a call for action.
Writing at the website thehill.com, they said: "In the United States...most people of faith appear to be woefully ignorant of the plight of their fellow believers in China.
"The persecution of Chinese Christians is rarely if ever mentioned on Sunday mornings in American megachurches.
"Raising awareness has been a long, slow struggle for the handful of organizations dedicated to the effort of exposing religious persecution in China and elsewhere.
"President Biden’s diplomatic boycott is a chance for Americans to act. Martin Luther King Jr. once famously said, 'In the end, we will remember not the words of our enemies, but the silence of our friends'. It’s time for American Christians to break their silence and stand up for their persecuted brothers and sisters in China."
They're calling for a time of prayer and fasting as well asking believers to put pressure on sponsors on politicians to act.
"Like all of history’s great tragedies, China’s systematic repression of faith will one day come to an end.
"Until then, it is incumbent upon those who have the ability and resources to do so to take action. No country actively committing genocide should ever be given the honor of hosting the Olympics," they said.
