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.

Rev. Steve Andrews, pastor at St. Matthew Lutheran Church in Lee’s Summit, MO, joins host Rev. Timothy Appel to study Luke 22:24-38.

Rev. Joel Heckmann, pastor at St. John’s Lutheran Church in Okarche, OK, joins host Rev. Timothy Appel to study Luke 20:41-21:4. After some of the scribes recognize that Jesus had spoken well, the Lord puts the question to them. He asks them how to interpret Psalm 110. They rightly recognize that the Christ is David’s son; how can Psalm 110 also call the Christ David’s Lord? Through His insightful...

Rev. Dr. Adam Filipek, pastor at Holy Cross and Immanuel Lutheran Churches in Lidgerwood, ND, joins host Rev. Timothy Appel to study Luke 18:15-30.

He rebukes His disciples when they attempt to stop these children from coming to Him, for only in such dependence upon t...

Rev. Ned Moerbe, pastor at Trinity Lutheran Church in Blackwell, OK, joins host Rev. Timothy Appel to study Luke 18:1-14.
