Tail wags dog?
Historically, most UK churches ran a central prayer meeting at the church.
This often had a Bible talk at the centre of it (and sometimes, bizarrely, not much prayer). But what started in the 1960s as a radical experiment has now become a standard feature of the life of most evangelical churches: small groups gathering week by week in people’s homes, led by ordinary church members. They may be called Bible study groups, growth groups or a host of other titles.
