Pentecostalism is a holistic faith, and the belief that Jesus is Healer is one quarter of the full gospel. Pentecostals cite four major reasons for believing in divine healing: 1) it is reported in the Bible, 2) Jesus' healing ministry is included in his atonement (thus divine healing is part of salvation), 3) "the whole gospel is for the whole person"—spirit, soul, and body, 4) sickness is a consequence of the Fall of Man and salvation is ultimately the restoration of the fallen world. In the words of Pentecostal scholar Vernon L. Purdy, "Because sin leads to human suffering, it was only natural for the Early Church to understand the ministry of Christ as the alleviation of human suffering, since he was God's answer to sin ... The restoration of fellowship with God is the most important thing, but this restoration not only results in spiritual healing but many times in physical healing as well." In the book "In Pursuit of Wholeness: Experiencing God's Salvation for the Total Person", Pentecostal writer and Church historian Wilfred Graves, Jr. describes the healing of the body as a physical expression of salvation.
