Two prayer services will be held at St. Louis gas stations to thank God for lower fuel prices and to ask that they continue to drop.

Darrell Alexander, Midwest co-chair of the Pray at the Pump movement, says prayer gatherings will be held Monday afternoon and evening at a Mobil station west of downtown St. Louis.

Participants say they plan to buy gas, pray and then sing "We Shall Overcome" with a new verse, "We'll have lower gas prices."

An activist from the Washington D.C. area, Rocky Twyman, started the effort, saying if politicians couldn't lower gas prices, it was time to ask God to intervene.

The group thinks the prayer is helping, saying prices are starting to fall below $4 a gallon.
