Small groups are essential for growing and maturing in the Lord. Some groups meet during Sunday School, before or during church on Sunday night, or on Wednesday night. Adults of all ages can always be part of a small group meeting at Oak Grove. Wednesday Night Prayer Meeting and Bible Study in the sanctuary is one of the most interesting services at Oak Grove. It is a time for in-depth study of various topics straight from the Bible plus a time to share prayer needs that are on your heart.
