Sunday School is the oldest of Oak Grove Baptist Church's education programs. Since its beginning in March 1889, Sunday School has grown. In the early days the roads leading to the church would become muddy in the winter causing Sunday School to close often in January, February and March. Originally all the Sunday School classes met in the church's auditorium.
Sunday School is the basic organization for the Bible teaching. The organization teaches the Bible and its application to life, and its relevance for today; and reaches persons for Christ and church membership.
In addition to its weekly classes the Sunday School department offers a January Bible Study on January Sunday nights. The Sunday School department oversees the church's Vacation Bible School each summer.
Sunday School meets every Sunday morning at Oak Grove. Literature from LifeWay Christian Resources of the Southern Baptist Convention is used by all classes.
