An altar call is a practice in some evangelical churches in which those who wish to make a new spiritual commitment to Jesus Christ are invited to come forward publicly. It is so named because the supplicants gather at the altar located at the front of the church building. In the Old Testament, an altar was where sacrifices were made. So, the name "altar call" refers to a believer "offering" themselves on an altar to God, as in Romans 12:1:

I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.

Most altar calls occur at the end of an evangelical address^{[citation needed]} invitation may be referred to as an "altar call" even if there is no actual altar present. Many preachers make use of the altar call; notable examples include Billy Graham, Benny Hinn, Franklin Graham and Reinhard Bonnke.^{[citation needed]} Congregations often sing a hymn, usually with a theme of invitation or decision, during the altar call. Some churches make use of the sinner's prayer, which people who come forward to be "saved" are asked to recite. It is sometimes said by the invitee that those who come forth are going to receive Jesus Christ as their Savior. This is a ritual in which the supplicant makes a prayer asking for his sins to be forgiven, acknowledges Jesus as the risen Son of God and pledges his/her devotion to Jesus and to live thereafter following Christ's teachings. This is often called being born again.^{[citation needed]}

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.

Keith Gordon Green (October 21, 1953 – July 28, 1982) was an American gospel singer, songwriter, musician, and Contemporary Christian Music artist originally from Sheepshead Bay, Brooklyn, New York. Beyond his music, Green is best known for his strong devotion to Christian evangelism and challenging others to the same. Often considered controversial for his frequently confrontational lyrics and spoken messages, he wrote some notable songs alone or with his wife, Melody Green, including "Your Love Broke Through", "You Put This Love in My Heart", and "Asleep in the Light". Green is also known for numerous popular modern hymns, including "O Lord, You're Beautiful" and "There is a Redeemer", written by his wife, Melody.

Keith took to music at a young age, beginning with the ukulele at age three, the guitar at five, and the piano at seven years of age. His talents were noted by a major newspaper by the time he was only eight years old. Following a performance of Arthur Laurents' The Time of the Cuckoo, a local review by the Los Angeles Times wrote that "roguish-looking, eight-year-old Keith Green gave a winning [character] portrayal" as "the little Italian street urchin, Mauro"; another review commented that he "stole the show". The show was Keith's first appearance in live theater, which was held in Chatsworth, California, in September 1962. According to the LA Times, Green had already "done a number of television commercials and...made a TV pilot."
