This is a more organized group that has regular meetings at a mission site, such as homes, coffee shops, and other available spaces. Most house churches do not have a pastor but are lay led. The main emphasis is to gather for worship, Bible study and prayer. This is an effective way of expanding the Christian faith without front-loading a mission plant with the burden of renting or owning worship space. A house church may begin with a small group of committed Christians in an area where no church exists, or it may be planted by an existing congregation branching out into a local neighborhood under the leadership of the mother congregation. The goal of a house church is not necessarily to grow into a larger congregation that requires its own building. Rather, a house church focuses on discipleship and depth.
