Christians worship through various acts such as raising hands, clapping, singing, playing musical instruments, reading scripture and praying. Different churches (denominations) worship in different ways.
In some churches the atmosphere of worship is quiet but in others it is loud. In some churches they my use prayer books while in others they pray "as the spirit leads".
Some churches believe in the infilling of the Holy Spirit and "speaking in tongues" while other do not. The common thread among Christians is the belief in Jesus as the Savior of mankind.
