We cannot grow alone and we need each other.
This is why the Bible encourages us to spend time with one another, encouraging each other, praying for one another, learning from each other, and loving one another. It is impossible to adequately do these things together in a large group like Sunday morning.
Therefore, we have many ministries and smaller groups that meet on Sundays and during the week. These groups provide a context for you to get to know others in the church better and for you to grow in your faith.
