Rocky Twyman of Washington, D.C., came to San Francisco over the weekend to stage a pray-in at a Chevron station. He is also calling on churchgoers to ask for God's intervention where he says politicians have failed.
Gas costing $4 a gallon or more has become common around the San Francisco Bay area.
The 59-year-old Twyman says people praying for cheaper fuel should also walk more and use car pools.
Twyman also works as a community organizer and public relations consultant. He has led campaigns to nominate Oprah Winfrey for the Nobel Peace Prize and to encourage African Americans to donate bone marrow.
