You may not know what that means, but it means they had to revamp everything they did. New songs and new emphasis on style of worship, etc. The whole dynamic of worship was changed to compete with what many of the larger denominations are doing. One preacher thought changing the dynamics of a congregation was what he needed to do to build the church. They changed the format of worship, bought new song books that had new praise type songs, changed the length of the service from an hour to two hours plus.
Sermons are much longer.
Although things have changed, there really hasn't been a big burst of growth. They have lost as many as they have gained through forcing the change. You have to know what is taking place when people say a church is growing. I received an email from a church I know very well. The person sending me the email was informing others how the church there was growing.
