Prayer plays an important role in Pentecostal worship. Collective oral prayer, whether glossolalic or in the vernacular or a mix of both, is common. While praying, individuals may lay hands on a person in need of prayer, or they may raise their hands in response to biblical commands (1 Timothy 2:8). The raising of hands (which itself is a revival of the ancient orans posture) is an example of some Pentecostal worship practices that have been widely adopted by the larger Christian world. Pentecostal musical and liturgical practice have also played an influential role in shaping contemporary worship trends, with Pentecostal churches such as Hillsong Church being the leading producers of congregational music.
