A revival meeting usually consists of several consecutive nights of services conducted at the same time and location, most often the building belonging to the sponsoring congregation but sometimes a rented assembly hall, for more adequate space, to provide a setting that is more comfortable for non-Christians, or to reach a community where there are no churches. Tents were very frequently employed in this effort in the recent past, and occasionally still are, but less so due to the difficulties in heating and cooling them and otherwise making them comfortable, an increasing consideration with modern audiences.
