In this sermon, we wrestle with Bonhoeffer's piercing question: "Are we still of any use?" Through his life and writings, we explore what it means for the church to be more than furniture in the background of our lives—to become Christ's visible presence in the world. Bonhoeffer's journey from academic theologian to prophetic voice shows us how the Sermon on the Mount calls us beyond theoretical faith into tangible action, challenging us to be the church that makes Christ present in times of crisis and suffering. (Matthew 5:1-16)
