There are many classes in which to learn and study the Bible at Good Shepherd. On Sunday mornings between the worship services each pastor leads a Bible Class on a different topic. The children's Sunday School also takes place at this time. Several times throughout the year the pastors conduct evening adult inquiry classes to study the basic teachings of the Christian faith and Lutheran theology. The classes are primarily designed for those who want to become confirmed, communicant members of Good Shepherd, but they are open to anyone.
Some members also have Bible study groups in their homes.
The main campus of Good Shepherd is located on 13 acres in northern Collinsville. It consists of the School, Gymnasium and old sanctuary complex which is connected to the new sanctuary by an enclosed, windowed walkway. The new sanctuary is a contemporary design with traditional features. Each floor is approximately 12,000 square feet. The lower level includes a walkout fellowship hall which is also used for Bible Classes with the help of a soundproof folding wall.
