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.

Preachers Sent by God Have Beautiful Feet 21.05.2020

Rev. Philip Hoppe, pastor at Peace Lutheran Church in Finlayson, MN and St. Paul’s Lutheran Church in Bruno, MN, joins host Rev. Timothy Appel to study Romans 10:14-21. The Lord promises to save all those who call on His name, and He provides for the creation of that saving faith. St. Paul lays out a step-by-step sequence of events. God sends the preacher. The preacher proclaims the Word. The Word...

Listen to the Righteousness Based on Faith 20.05.2020

Rev. Dr. Adam Filipek, pastor at Holy Cross Lutheran Church and Immanuel Lutheran Church in Lidgerwood, ND, joins host Rev. Timothy Appel to study Romans 10:5-13. The righteousness based on the law and the righteousness based on faith speak two different words. The righteousness based on the law says: “Do this! Don’t do that!” This is not an evil or sinful word; it is holy and good. However, becau...

True Zeal Pursues Righteousness through Faith 19.05.2020

Rev. Sam Wirgau, pastor at Bethlehem Lutheran Church in Ossian, IN, joins host Rev. Timothy Appel to study Romans 9:30-10:4. What shall we say then? In this text, St. Paul summarizes what he has said concerning Israel’s rejection of Christ and transitions to the importance of faith. Although Gentiles had not pursued righteousness, even pursuing unrighteousness, they attained God’s righteousness th...

God Acts with Righteousness and Mercy 18.05.2020

Rev. Dan Speckhard, pastor at Faith Lutheran Church in Godfrey, IL joins host Rev. Timothy Appel to study Romans 9:14-29. God has not shown any unrighteousness in His dealings with people. His mercy and compassion were on full display for Israel in the aftermath of their gross idolatry with the golden calf. Pharaoh’s calloused heart could not stand in the way of God accomplishing His merciful purp...

God’s Righteousness Has Not Failed 15.05.2020

Rev. Sean Kilgo, pastor at the Northeast Kansas Lutheran Partnership, joins host Rev. Timothy Appel to study Romans 9:1-13. On the heels of the glorious conclusion of Romans 8, this text may seem like a step backward. Yet St. Paul is here continuing his proclamation of God’s righteousness in Christ. Though this glorious gift has largely been rejected by those physically descended from Abraham, tha...

The Most Beautiful Text in the Bible 14.05.2020

Rev. Stephen Preus, pastor at Trinity Lutheran Church in Vinton, IA, joins host Rev. Timothy Appel to study Romans 8:31-39. With this glorious text, St. Paul draws to a grand conclusion all that he has laid out so far in the epistle to the Romans. He asks and answers multiple questions for the comfort and certainty of Christians. Considering the truth of justification by grace through faith for th...

The Cosmic Hope of Redemption 13.05.2020

Rev. David Appold, pastor at St. Paul Lutheran Church in Paducah, KY, joins host Rev. Timothy Appel to study Romans 8:18-30. Jesus came for you, but He didn’t come just for you. Jesus came for His whole creation. The whole creation is groaning under bondage to corruption due to mankind’s sin. That is why creation eagerly longs for the revealing of the sons of God, that fully restored mankind would...

Adopted as Heirs of God without Distinction 12.05.2020

Rev. AJ Espinosa, pastor at St. Paul’s Lutheran Church in Irvine, CA and host of Thy Strong Word on KFUO Radio, joins host Rev. Timothy Appel to study Romans 8:12-17. The indwelling of the Holy Spirit in Christians has profound implications. Now that the debt of sin has been forgiven in Christ, Christians no longer owe allegiance of sin to the flesh but rather give the due of love in service to Go...

Now No Condemnation in Christ 11.05.2020

Rev. Zelwyn Heide, pastor at St. Peter Lutheran Church in Hannover, ND and Zion Lutheran Church in New Salem, ND, joins host Rev. Timothy Appel to study Romans 8:1-11. St. Paul reaches one of the high points of the epistle, drawing together all that he has said concerning the unrighteousness of man and the righteousness of God. For those who are in Christ, there is now no more condemnation. The re...

The Struggle Is the Sign of Life 08.05.2020

Rev. Dr. Adam Koontz, assistant professor of exegetical theology at Concordia Theological Seminary in Ft. Wayne, IN, joins host Rev. Timothy Appel to study Romans 7:14-25. St. Paul describes his own struggle against sin as a Christian; this is the struggle of every Christian. Such a realistic description keeps us from self-justification. Even St. Paul the Apostle, upon self-examination and reflect...

My Evil Sin Takes Advantage of God’s Good Law 07.05.2020

Rev. Dr. Phil Booe, pastor at Christ Lutheran Church in Hebron, CT, joins host Rev. Timothy Appel to study Romans 7:1-13. Christians are under grace; they are no longer under the law. How did this happen? St. Paul uses the human example of the law of marriage. All Christians can understand this truth from God’s Word. Marriage, the good gift of God before the fall into sin, unites one man and one w...

Free Slaves of God 06.05.2020

Rev. Clint Poppe, pastor at Good Shepherd Lutheran Church in Lincoln, NE, joins host Rev. Timothy Appel to study Romans 6:12-23. God’s gracious action in Christ delivered in Holy Baptism means that sin is no longer the Christian’s king or lord. Therefore, St. Paul commands that we must not live in our bodies as if sin is our king. Though we think sin is under our control, sin quickly progresses to...

Baptized into Christ 05.05.2020

Rev. Steve Andrews, pastor at St. Matthew Lutheran Church in Lee’s Summit, MO, joins host Rev. Timothy Appel to study Romans 6:1-11. If God loves to forgive and we love to sin, should we just keep on sinning? St. Paul answers in clearest terms: “Absolutely not!” Sin no longer is the defining reality for Christians because Christians have died to sin. God has accomplished this in Holy Baptism. When...

The Life in Christ is Greater than the Death in Adam 04.05.2020

Rev. David Vandercook, pastor at Trinity Lutheran Church in North Little Rock, AR and Shepherd of Peace Lutheran Church in Maumelle, AR, joins host Rev. Timothy Appel to study Romans 5:12-21. The unrighteousness of all can be traced to one man, Adam, just as the righteousness of God freely given to all can be traced to one man, Jesus Christ. Sin invaded God’s good creation through Adam. Through th...

Justification’s Past, Present, and Future 01.05.2020

Rev. Andrew Preus, pastor at Trinity Lutheran Church in Guttenberg, IA and St. Paul Lutheran Church in McGregor, IA, joins host Rev. Timothy Appel to study Romans 5:1-11. St. Paul begins to expound upon the fruit of justification through faith in the life of the Christian. Because God has declared sinners righteous through faith in Jesus Christ, we have peace with God. This present reality is grou...

Righteous-ified through Faith in Jesus 30.04.2020

Rev. Peter Ill, pastor at Trinity Lutheran Church in Millstadt, IL, joins host Rev. Timothy Appel to study Romans 4:13-25. St. Paul continues to expound upon Abraham as the example of the righteousness of God that comes through faith. The inheritance given to Abraham and his offspring depended not on works, but upon a promise. The background of Israel’s inheritance of the land shows quite clearly...

God Credits Faith in Jesus as Righteousness 29.04.2020

Rev. Joel Heckmann, pastor at St. John’s Lutheran Church in Okarche, OK, joins host Rev. Timothy Appel to study Romans 4:1-12. Justification by grace through faith is nothing new. Abraham, who stood as the greatest example of righteousness among Jews, was declared righteous by God through faith. St. Paul quotes from Genesis 15 to make his point. “Abraham believed God, and it was counted to him as...

The Gospel Turn 28.04.2020

Rev. Harrison Goodman, pastor at Mount Calvary Lutheran Church in San Antonio, TX, joins host Rev. Timothy Appel to study Romans 3:21-31. The tiny conjunction, “but,” makes all the difference. Our works according to the Law cannot make us righteous, but God has manifested His righteousness apart from the Law. This righteousness is seen clearly in the crucifixion and resurrection of the Lord Jesus...

The Climax of Unrighteousness 27.04.2020

Rev. Jeremiah Johnson, pastor at Glory of Christ Lutheran Church in Plymouth, MN, joins host Rev. Timothy Appel to study Romans 3:9-20. St. Paul builds to his climax of preaching that all people are unrighteous. Jews and Gentiles alike are under sin; they are slaves bound to this terrible master. The Apostle strings together a rapid fire list of one Old Testament passage after another in order to...

The Christian’s Struggle Between the Old Self and New Self 25.04.2020

Rev. Dr. Rick Marrs, associate professor of practical theology at Concordia Seminary, St. Louis and author of Making Christian Counseling More Christ Centered, joins host Rev. Timothy Appel to study the distinction between the old Adam and new Adam. In distinguishing the old Adam and new Adam, God’s Word lays out an important distinction that Christians daily experience. The old self is the corrup...

The Proper Distinction Between Law and Gospel 23.04.2020

Rev. Ryan Ogrodowicz, associate pastor and headmaster at Grace Lutheran Church and School in Brenham, TX, joins host Rev. Timothy Appel to study the proper distinction between Law and Gospel. The proper distinction between Law and Gospel is a glorious light that opens the Holy Scriptures to us; apart from this distinction, the Bible remains a closed book. The Law is the revealed will of God for Hi...

Let God Be God 22.04.2020

Rev. Brady Finnern, pastor at Messiah Lutheran Church in Sartell, MN, joins host Rev. Timothy Appel to study Romans 3:1-8. As St. Paul preaches that all men are unrighteous, objections arise, but the Apostle will not let any of them stand. If all stand condemned by the Law, Jews questioned the importance of having been a part of God’s people under the covenant of circumcision. The advantage was no...

Confidence in the Law Won’t Save from Sin and Death 21.04.2020

Rev. Tim Koch, pastor at Emanuel Lutheran Church in Milbank, SD, joins host Rev. Timothy Appel to study Romans 2:12-29. St. Paul continues to strip away from sinners all confidence apart from Christ. The problem is sin and death. Those who sin die, with or without the Law. The Law requires action, not only hearing, from both Gentiles and Jews alike. Though the Gentiles did not have the Law written...

God’s Righteous Judgment 20.04.2020

Rev. Gaven Mize, pastor at Augustana Evangelical Lutheran Church in Hickory, NC joins host Rev. Timothy Appel to study Romans 2:1-11. St. Paul’s “they” of Romans 1 becomes “you” in Romans 2. Those who have heard the proclamation of God’s wrath against the unrighteousness of man are left with no excuse. To pass judgment on “them” is to recognize the justice of judgment upon oneself. Comparison to a...

God’s Righteous Wrath against Man’s Unrighteousness 17.04.2020

Rev. Dustin Beck, pastor at Holy Cross Lutheran Church in Warda, TX, joins host Rev. Timothy Appel to study Romans 1:18-32. Having proclaimed that the Gospel is God’s power to save, St. Paul begins to lay out why humanity needs salvation at all. God’s righteousness to save sinners goes hand-in-hand with His wrath against man’s unrighteousness. The unrighteousness of man expresses itself in the sup...
