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. Dr. Adam Filipek, pastor at Holy Cross Lutheran Church and Immanuel Lutheran Church in Lidgerwood, ND, joins host Rev. Timothy Appel to study 2 Thessalonians 1:1-12.

Rev. James Preus, pastor at Trinity Lutheran Church in Ottumwa, IA, joins host Rev. Timothy Appel to study 1 Thessalonians 5:1-11. Though Paul has already taught the Thessalonians concerning the Lord’s return, he writes to them in order to nourish and reinforce their faith so that they will meet that Day with confidence and joy. The Day of the Lord will be unexpected, like a thief in the night. Th...

Rev. David Appold, pastor at St. Paul Lutheran Church in Paducah, KY, joins host Rev. Timothy Appel to study 1 Thessalonians 4:13-18. Only Christians have true comfort in the face of death.

Such grief acknowledges dea...

The Unity of the Church Together and Apart --- 2019/12/05 05.12.2019

Rev. Paul Pater, pastor at Shepherd of the Ridge Lutheran Church in North Ridgeville, OH and Hope Lutheran Church in Sheffield Village, OH, joins host Rev. Timothy Appel to study 1 Thessalonians 2:17-3:5. Paul’s stay with the Thessalonians had been brief, probably only a month.

Rev. Chris Hull, pastor at Zion Lutheran Church in Tomball, TX joins host Rev. Timothy Appel to study 1 Thessalonians 2:13-16. Paul’s thanksgiving for the Thessalonians continues.

Rev. Mark Barz, senior pastor at Crown of Life Lutheran Church in San Antonio, TX joins host Rev. Timothy Appel to study 1 Thessalonians 2:1-12.

Rev. Sam Wirgau, pastor at Bethlehem Lutheran Church in Ossian, IN joins host Rev. Timothy Appel to study Luke 17:11-19.

These men not only suffered greatly physically from this terrible illness. Even more than that, they were sepa...

The Joy of Thanksgiving --- 2019/11/28 27.11.2019

Rev. John Bussman, pastor at St. Paul’s Lutheran Church in Cullman, AL joins host Rev. Timothy Appel to study Philippians 4:6-20.

Disciplined for Thanksgiving --- 2019/11/27 27.11.2019

Rev. Harrison Goodman, pastor at Mt. Calvary Lutheran Church in San Antonio, TX, joins host Rev. Timothy Appel to study Deuteronomy 8:1-10. Before the LORD brings Israel into the Promised Land, Moses invites the people to reflect upon the goodness of the LORD’s commandments. This is no romanticized memory; rather, they recall the dirty details of their wilderness wanderings in which the LORD humbl...

The Gospel according to Amos --- 2019/11/26 26.11.2019

Rev. Jeremiah Johnson, pastor at Glory of Christ Lutheran Church in Plymouth, MN, joins host Rev. Timothy Appel to study Amos 9:11-15. Amos ends with two-hundred proof Gospel. Though it comes seemingly out of nowhere, Amos’ final preaching fits the LORD’s pattern of mercy throughout the Old Testament and serves as a reminder of the unmerited nature of grace. Once again, the day of the LORD comes u...

The Final Judgment --- 2019/11/25 25.11.2019

Rev. Ryan Ogrodowicz, associate pastor and headmaster at Grace Lutheran Church and School in Brenham, TX, joins host Rev. Timothy Appel to study Amos 9:7-10.

Rev. Matt Wietfeldt, director of admissions and the Christ Academy program at Concordia Theological Seminary in Ft. Wayne, IN, joins host Rev. Timothy Appel to study Amos 9:5-6.

As the Source of justice and righteousness...

Amos’ Vision of the LORD --- 2019/11/21 21.11.2019

Rev. Brady Finnern, pastor at Messiah Lutheran Church in Sartell, MN, joins host Rev. Timothy Appel to study Amos 9:1-4. In Amos’ fifth and final vision, he sees the LORD Himself. The dead heterodoxy of Israel is about to yield its terrible result. The LORD has told His people to prepare to meet Him, and now He meets them, only not in grace, but judgment. He stands beside the idolatrous altar in B...

A Famine of God’s Word --- 2019/11/20 20.11.2019

Rev. Stephen Preus, pastor at Trinity Lutheran Church in Vinton, IA, joins host Rev. Timothy Appel to study Amos 8:7-14. The LORD continues His commentary on Amos’ fourth vision. He swears by Himself as the true Pride of Jacob, in contrast to their idolatrous boasting in themselves and their accomplishments. His oath is terrifying, as He promises that He will no longer forget the sins of His peopl...

God Gets to the Heart of the Matter --- 2019/11/19 20.11.2019

Rev. Christopher Jackson, pastor at St. John Lutheran Church in Algoma, WI and St. Peter Lutheran Church in Forestville, joins host Rev. Timothy Appel to study Amos 8:4-6.
