NASHVILLE, Tenn. (UMNS) - A nationwide prayer campaign for college students and campus ministries, "Pray 40," begins Aug. 23 when United Methodists are asked to pray for students and campus ministries for 40 days. Some 17 million U.S. students head to colleges and universities each autumn, while millions more flood campuses worldwide. The campaign will feature 40 prayers written by students, campus pastors, bishops and church leaders. The Upper Room will publish the prayers. Participants can sign up to receive a daily prayer by e-mail, download and share a prayer guide, follow the effort on Twitter or by text, commit to a 24-hour period of continuous prayer and teach about prayer. The website—ww.Pray40.com—will launch Aug. 2.
