This week for our Community Gathering for Worship, we welcomed Dr. Roger Olson to the pulpit. Dr. Olson currently serves as the Foy Valentine Professor of Christian Theology and Ethics at George W. Truett Theological Seminary. We were also pleased to welcome Christian musician and composer Bill Gaither. The title for Dr. Olson's sermon is: "Certainty Not," and it is drawn from Proverbs 3:5-6
