The order of service is similar to other Pentecostal churches, for example the Assemblies of God. There is no formal order of service, but most churches follow a routine of congregational singing, an offering/tithe collection, prayer, a sermon and an altar call. During the service, congregants may operate in various spiritual gifts, such as a message in tongues, a prophecy and words of wisdom or knowledge, as inspired by the Holy Spirit. During the congregational singing part of a service, a believer's attitude of worship is often expressed through raising their hands in the orans posture.
