Evangelical Christians are using social networking sites like Facebook and Twitter to encourage people to pray for -- and help the victims of Japan's earthquake and tsunami.

"That's one of the great advantages of social networking sites -- whether it's Facebook or Twitter," said Dr. Thom Rainer, president of LifeWay Christian Resources. "This is one case where we evangelical Southern Baptists are using these resources to help Japan."

Rainer said Southern Baptists are mobilizing to send food and medical supplies to Japan.

"They will also be seeking to minister not only to their physical need, but their spiritual needs as well," Rainer said.

Rick Warren, the pastor of of Saddleback Church in California, tweeted Saturday night, urging people to pray. Warren said he lived in Nagasaki as a missionary.

"YOU can give to help earthquake victims in japan. 2,100 of our members serve on PEACE Relief Teams," he tweeted, according to Christian Post.
