Discipleship Model Details
Each year some unbelievers attend church, the Potential Converts. Some get converted and want to go deeper into Basic Discipleship. Some get converted but decided to go no further, "stop at conversion". They keep attending church but do not progress much in the Christian life. The others are not converted, and say "no thanks". They spend a while as people now hardened to church, "dipped toe in church", but do again become open to trying church again, like other unbelievers.
Of those in Basic Discipleship, some progress no further, but other progress on to Early Mature and play a full spiritual part in the church. A fraction of those who stop leave the church each year.
Of the "Early mature", some take on lay leadership and become mature, some do not and stay at the early mature. Both early mature and mature eventually retire from active service and become inactive in the church. Although those who stopped at conversion and the basic discipleship stages are also inactive in a spiritual sense, the specific "Inactive" category represent those who were once active but are no longer.
