Instead of a spring concert, Midwestern Baptist Theological Seminary (MBTS) is inviting Missouri churches to one of the grandest traditions in Baptist life: a hymn sing. Featured guests are Matt Boswell, a modern hymnwriter who has penned hymns including “His Mercy is More,” “Christ the Sure and Steady Anchor,” “Come Behold the Wondrous Mystery,” and A.L. “Pete” Butler, a retired Midwestern professor who wrote the tune to the famous Fanny Crosby hymn, “Redeemed.”
