Evangelicalism is a Protestant Christian movement which began in the 17th century and became an organized movement with the emergence around 1730 of the Methodists in England and the Pietists among Lutherans in Germany and Scandinavia. The movement became even more important—drawing far more members than in Europe—in the United States during the series of Great Awakenings of the 18th and 19th century. It continues to draw adherents globally in the 21st century, especially in the poor nations of the Third World.

It is a religious movement that de-emphasizes ritual and emphasizes the pietism of the individual, requiring him or her to meet certain active commitments, including:

David Bebbington has termed these four distinctive aspects conversionism, biblicism, crucicentrism, and activism noting, "Together they form a quadrilateral of priorities that is the basis of Evangelicalism."

The term evangelical has its etymological roots in the Greek word for "gospel" or "good news": ευαγγελιον (evangelion), from eu- "good" and angelion "message". In that sense, to be an evangelical would mean to be a believer of the Gospel, that is the message of Jesus Christ.

Paul David Washer (born 1961) is the Founder/Director & Missions Coordinator of HeartCry Missionary Society which supports indigenous missionary work. He is also a Southern Baptist itinerant preacher. Washer's sermons tend to have an evangelistic focus on the gospel and the doctrine of the assurance of salvation, and he frequently speaks against practices such as the sinner's prayer, and a focus on numerical church growth.

Washer had a born again experience while studying to become an oil and gas lawyer at the University of Texas. Upon graduation, he attended Southwestern Baptist Theological Seminary and achieved a Master of Divinity degree. He then moved to Peru to become a missionary for 10 years, after which he returned to the United States. Washer resides in Radford, Virginia, where he lives with his wife and three children.

Washer's sermons often focus on the character of Christ and how a person is saved from hell. According to Washer, a person is saved through faith alone, but the evidence of a person's repentance is by walking with Jesus. Washer claims that most people who profess a belief in Christianity aren't truly saved. Washer blames preachers, as he claims many preachers often say a person is saved without looking for evidence of repentance in that person's life.

William Franklin "Billy" Graham, Jr. (born November 7, 1918) is an American evangelical Christian evangelist, ordained as a Southern Baptist minister, who rose to celebrity status with national media backing of William Randolph Hearst and Henry Luce in 1949. His sermons were broadcast on radio and television, with some still re-broadcast today.

Graham is notable for having been a spiritual adviser to several United States Presidents; he was particularly close to Dwight D. Eisenhower and Richard M. Nixon. During the civil rights movement, he began to support integrated seating for his revivals and crusades; in 1957 he invited Rev. Martin Luther King, Jr. to jointly preach at a huge revival in New York City, where they appeared together at Madison Square Garden, and bailed the minister out of jail in the 1960s when he was arrested in demonstrations.

Having built an evangelical empire and organized huge events worldwide, Graham has personally preached the Gospel to more people than any other person in history. His institutions include a variety of media and publishing outlets. According to his staff, more than 3.2 million people have responded to the invitation at Billy Graham Crusades to accept Jesus Christ as their personal Savior. As of 2008, Graham's estimated lifetime audience, including radio and television broadcasts, topped 2.2 billion.
