In Cornerstone you can expect a powerful blend of Biblical teaching, modern praise and worship music, and a casual, friendly environment. Each week we’ll sing traditional hymns and contemporary songs of faith, and take an in-depth look at scripture and practical wisdom for living out our faith today. An extended and in-depth exploration of scripture or core Christian teaching is shared to help participants understand what the scriptures and the teachings of the church meant in their original context and how they might be applied to lives today. This service engages in congregational singing and praying, hearing and reflecting on God’s Word in the scriptures and preaching, and celebrating God’s loving and transforming presence in the sacrament of the Lord’s Supper. Our Munger Place campus is a unique historical venue in East Dallas with a quickly growing congregation that focuses on community and family.
