The Adult Sunday School classes are designed to continue to mature the saints. There are often two or more classes offered. Topics alternate between foundational classes (membership, bible survey, etc), Bible books, practical classes (marriage, worldview, Christian living, etc), and systematic theology (doctrine, confessions, etc). We throw in things like Church History to round things out.
Our current Adult Sunday school class, "New Hope's Vision: Where are We Going?" is being held in the sanctuary. This class runs for 12 weeks (January 11-March 29) and is being taught by the elders of the church.
