As we have just seen, Sunday School develops many for the work of Sunday School, but she also equips people for the work of other ministries in the church. If you were to eliminate Sunday School, you would see a gradual decline in workers being produced in other ministries as well. Sunday School is the foundational ministry from which other ministries are able to sprout.
How effective would other ministries in the church be if there were no Sunday School? Can you imagine ministries with leaders that had never been nurtured and discipled in a Sunday School class? For example, how effective would Awana leaders, discipleship teachers, altar counselors, evangelism trainers, counselors leading devotions at children’s/youth camp, DiscipleNow Weekend, and others, be if they were not nurtured by a Sunday School class? At the least we would have to say that they probably would not be as equipped as they could be.
