In this biblical, theological, and contextual study of prayer, Dr. Mireya Álvarez argues that Latino Pentecostals practice prayer as a way to enter into the presence of God. In the Latino community, the manifestations of the Holy Spirit are experienced in spontaneous prayers, joyful singing, speaking in tongues, and in an openness to unplanned liturgical movement. For immigrants undergoing culture shock and feelings of disorientation, the church becomes a community of acceptance and consolation where they can cry, laugh, and express unrestrained worship. Álvarez grounds her theology of prayer on a biblical study of Luke-Acts, arguing that Latino Pentecostal prayer aligns with Luke's theology of prayer. Luke-Acts reveals the redemptive-historical acts of God occurring in a context of prayer. Álvarez traces the function of prayer in Pentecostalism, focusing on Hispanic and Latino churches. She interviews Latino immigrants and learns how prayer helped them cope with hardship, grief, depression, and blatant discrimination. Álvarez concludes that Latino churches must keep prayer alive to preserve their vitality and to bring renewal to the church in America.
