Evangelical Christianity is quietly flourishing among migrant groups in the Gulf as churches provide low-paid workers facing horrific abuse with aid in times of crisis.
About 30 million migrant workers live in Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates. Migrants make up most of the population in some places, with up to 80% employed in construction, hospitality and domestic jobs.
Many, including those from Hindu and Catholic backgrounds, are now converting to evangelicalism and Pentecostalism.
