When Muslims begin the holy month of Ramadan this weekend, Christians worldwide will be praying along with them. But Muslims might not welcome the support. In a campaign called the "30 Days Muslim Prayer Focus," Christians will be asking God to help Muslims accept Jesus.

The project is organized by a loose association of evangelical groups that include Youth With A Mission, which works in about 150 countries. In the U.S., the National Association of Evangelicals is asking the thousands of churches and ministries it represents to participate.
