Community has power. Prayer in unison with others has an efficacy greater than the sum of the individual prayers. This is true no matter how large the group, from a pair to an entire church, hall or stadium. The spiritual energy combines to enliven each member of the community and to create a bond among the members as well as to blend the voices of the congregants into the universal, eternal sound, the music that is the I AM, becoming one voice of blessing.
