Sharper Iron from KFUO Radio

Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its narrow detail, all for the sake of proclaiming Christ crucified and risen for sinners. Two pastors engage with God’s Word to sharpen not only their own faith and knowledge, but the faith and knowledge of all who listen. Sharper Iron is underwritten by Lutheran Church Extension Fund, where your investments help support the work of The Lutheran Church—Missouri Synod. Visit lcef.org.
