People are leaving churches, period - reagardless of the reason. Smaller, conservative churches are growing because people who still want to attend church can't stand the liberalism, but the overall trend is that for every ten people quitting a liberal church, two or three join conservative churches and the rest choose to remain unchurched.
Well .. that may be partly true .. but unless people are totally soured on "church" - many of them are eventually drawn in through friends, or a ministry they see on TV.
Since our Pastor went on the radio, we have drawn in a lot of people who were looking for that type of message.
