Jesus had both his public ministry to the multitudes and his personal discipleship of his own disciples. His public teaching ministry looked much like Marge’s teaching method (the history teacher in the video above) and his day-to-day discipleship looked more like Tom’s (the guitar tutor from the same video). Today’s churches try to apply this the same idea of teaching large groups and tutoring smaller ones, of lecturing to the big group and listening to one another in small group. To accommodate large group lectures, churches usually build auditoriums. To accommodate programs with smaller gatherings such as Sunday School classes and Bible studies, they often add on classrooms.
