Oral Roberts University, based in Tulsa, Oklahoma, is the largest charismatic university in the world. The school has an enrollment of over 5,000 students from every state in the US and attracts a significant number of international students. Futuristic architecture trims the campus, with the trademark Prayer Tower in the center. The 200-foot tower is said to resemble "an abstract cross and crown of thorns" and houses the Abundant Life Prayer Group on the observation deck. The Abundant Life Prayer Group is an outreach of the Oral Roberts Ministries, where people can call in to pray with a prayer partner. Mabee Center, an arena seating over 11,000 people, is located at the southwestern edge of the campus and is home to basketball games, concerts, church services, and satellite television productions.

All students are required to live according to an honor code prohibiting smoking, drinking, gambling, illicit sexual acts, and homosexual behavior.
