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.

1 Thessalonians 1:1-10: Thanksgiving for Faith, Love, and Hope 02.12.2025

Paul, Silas, and Timothy greet the church in Thessalonica in the grace and peace that comes from God the Father and the Lord Jesus Christ. They give thanks to God for the faith, love, and hope He has given to the Thessalonians. This fruit was produced among them by the Gospel, so that they imitated the Lord Jesus and the apostles as they suffered with great joy. This set an example to Christians t...

Acts 17:1-15: Paul’s Thessalonian Fan Club 01.12.2025

Paul and Silas visited Thessalonica as a part of the 2nd Missionary Journey. As was their custom, they first went to the synagogue to preach from the Old Testament that Jesus is the Christ. Many believed, but many did not. Those that did not became jealous and caused such trouble for the Christians in Thessalonica that Paul and Silas left more quickly than they would have liked. In Berea, the Word...

NEW SERIES: Yearning for the Day of Christ's Returning 01.12.2025

“Yearning for the Day of Christ’s Returning” is a mini-series on Sharper Iron that studies St. Paul’s two epistles to the Thessalonians. Although Paul's time in Thessalonica was brief, he had great affection for the Christians there. His two letters to the Thessalonians show us the joy that God gives us together in the Church and encourage us to live faithfully in expectation of Jesus’ coming on t...

Psalms of Thanksgiving - Psalm 136: The Refrain of Thanksgiving (Rebroadcast) 28.11.2025

The antiphonal nature of Psalm 136 is seen in the repeated second half of every verse: “His steadfast love endures forever.” This psalm helps us to give thanks to the LORD for His steadfast love shown forth in His work of creation, redemption, and His ongoing care for His people. For these reasons and more, we give thanks to the LORD, for He is good!  Rev. David Vandercook, pastor at Trinity Luthe...

Psalms of Thanksgiving - Psalm 100: A Psalm for Giving Thanks (Rebroadcast) 27.11.2025

The superscription of Psalm 100 identifies its purpose: to lead us into thanksgiving of the one true God. We join our voices to all creation when we make a joyful noise to the LORD, not only in our daily vocations, but especially in the Divine Service. We sing to Him because He has created us and saved us as our Good Shepherd. All of the LORD’s work for us comes from the reality that He is good, a...

LSB 895, “Now Thank We All Our God” 26.11.2025

Martin Rinckart wrote this hymn as a mealtime prayer for his children. Despite terrible suffering from war and famine, Rinckart was able to give thanks to God for His overflowing gifts. Such Christian thanksgiving is found in the heart and shows forth into the voice and hands as well. God is the One who knits us together in our mothers’ wombs, and He is the One who guides us in the way, His Son, J...

LSB 892, “Come, Ye Thankful People, Come” 25.11.2025

In this hymn, Henry Alford helps Christians to give thanks to God not only for the earthly harvests He gives in their seasons, but especially for the heavenly harvest that we long for on the Last Day. Even as we join together to thank God for the harvest of crops, we come into His presence to thank Him for bringing us into His Church through the preaching of His Word. We pray that He would make th...

LSB 813, “Rejoice, O Pilgrim Throng” 24.11.2025

Edward Plumptre wrote this hymn as a processional hymn, inviting those who sing to consider themselves as pilgrims through this life to the eternal life in Christ’s presence. As we journey together, we sing our praises together with the whole Church, following Christ crucified as our leader. We sing with our fathers who have come before us, with saints now, and with angel choirs, toiling as the Lo...

LSB 797, “Praise the Almighty” 21.11.2025

In this hymn, Johann Herrnschmidt writes a metrical paraphrase of Psalm 146 and proclaims the work of Christ. The Lord is the Almighty whose holy name we adore for the entirety of our lives. Rather than trusting in mortal rulers who cannot save us from death, we trust in Christ who has conquered death for us. Those who have Christ as their help are blessed, for He helps the penitent, the weak, and...

LSB 791, “All People That on Earth Do Dwell” 20.11.2025

In this hymn, William Kethe provides a metrical paraphrase of Psalm 100, in which God’s people are called to give Him thanks. Together, we make a joyful noise to God as we come before Him with cheerful voices. The Lord is our God who has created us apart from our merit and strength. The Lord is our Good Shepherd who has made us members of His flock. The Triune God does all of this because of His s...

LSB 790, “Praise to the Lord, the Almighty” 19.11.2025

Joachim Neander draws from Psalm 103 and other texts to call Christians to praise the Lord as the Almighty Creator. The Lord is the One who still reigns over all He has made, as Christians have seen time and time again. Not only has God created us with intricate care, but He also bestows good gifts and rescues us from various distresses. As we ponder all that God has done for us, we are drawn toge...

LSB 754, “Entrust Your Days and Burdens” 18.11.2025

Paul Gerhardt wrote this hymn as an acrostic poem using the words of Psalm 37:5. He encourages Christians to entrust all their burdens to the true God. Because He created and sustains all things, we can rely on Him to guide us and call out to Him in prayer, trusting His love. Through trials, we continue to trust in Him, awaiting His time with patience. We know that He will keep His promise, as He...

LSB 737, “Rejoice, My Heart, Be Glad and Sing” 17.11.2025

In this text from Paul Gerhardt, each Christian encourages himself to rejoice and maintain a cheerful trust in God for all things. He is our portion and treasure so that despair need not overwhelm us. As He has cared for us our whole lives long, so He will continue to care for us. His discipline comes from His love for us, the same love that has forgiven our sins in Christ. Therefore, we trust His...

NEW SERIES: Songs of Thankfulness and Praise 17.11.2025

“Songs and Thankfulness and Praise” is a mini-series on Sharper Iron that studies a variety of hymns of thanksgiving from Lutheran Service Book. Thanksgiving is a way of life for Christians as we realize that all gifts come from God’s fatherly love for us. In times of joy and sorrow, we return our thanks to Him for His never-ending goodness and mercy. Sharper Iron, hosted by Rev. Timothy Appel, lo...

Philemon 1-25: A Letter of Pastoral Care 14.11.2025

When Philemon, a prominent member of the Christian congregation in Colossae, needs pastoral care, St. Paul writes to him in humility. The Apostle gives thanks for the fruit of faith that Philemon has brought forth and appeals to Philemon to bring forth that same fruit now toward his runaway slave, Onesimus. St. Paul reminds Philemon that Onesimus is now a fellow brother in Christ who has been usef...

Colossians 4:2-18: Connected in Christ 13.11.2025

As the Apostle Paul began his letter to the Colossians by speaking of his prayers for them, so he concludes his letter by asking the Colossians to pray for him. Their prayers should be steadfast in thanksgiving and ask God to open the door for Paul to preach the Word, even though he is currently in prison. The Word of God that Christians speak is true and gracious, and Christians look for opportun...

Colossians 3:18-4:1: The Philosophy of Christ 12.11.2025

St. Paul does not leave his instruction for Christian life as vague theologizing. Rather, he instructs Christians on how to follow the Word of Christ in their closest relationships with each other. As Christians are given to live together as wives and husbands, as children and parents, and as workers and masters, we do so in Christ, that is, with the perspective that Christ has given us through Hi...

Colossians 3:5-17: Put on Christ 11.11.2025

St. Paul grounds his teaching concerning the Christian life in the reality of Holy Baptism. There, Christians die and rise with Christ. Now, Christians daily put off the old way of life as a dirty garment that no one would ever want to wear. At the same time, Christians daily put on the life given by Christ. That life is bound together in forgiveness and love that comes as the Word of Christ dwell...

Colossians 3:1-4: Your Life Is Hidden with Christ 10.11.2025

St. Paul encourages Christians to live in light of the reality that we have been raised with Christ. Rather than seeking the things of man, Christians set their minds on the things taught by Christ, because He sits at the right hand of God. We have died to the life of the sinful flesh, and our lives are hidden with Christ. We have this life truly by faith right now, waiting and praying for the Day...

Colossians 2:16-23: Hold Fast to the Body, Not the Shadow 07.11.2025

Because Christ has triumphed in the cross, no one can judge Christians based on those things that Jesus has fulfilled. The Old Testament regulations concerning food and drink and Sabbaths are a shadow of the body of Christ who has now been revealed. Although false preachers peddle practices that may look religious, any worship or piety that does not teach us to cling to Christ has no value. Only C...

Colossians 2:6-15: Christ’s Cruciform Triumph Over All Powers 06.11.2025

Because the Colossians have received Jesus, St. Paul exhorts them to walk in Him and remain rooted in the faith He has established in them. They must not be taken captive by philosophies that are only manmade traditions, for these are not from Christ. He is the One in whom the fullness of deity dwells bodily, and He has filled His Church. In Holy Baptism, He has incorporated His Church into His bu...

Colossians 1:24-2:5: Christ in You 05.11.2025

Even as St. Paul suffers in prison, he rejoices as such suffering is his participation in the Body of Christ, the Church. Because of God’s gift, St. Paul is a minister in the Church given to proclaim the mystery now revealed even to Gentiles that Christ dwells in believers. Proclaiming Christ, Paul has been struggling for the Colossians and other Christians whom he has not yet met so that they wil...

Colossians 1:15-23: In All Things 04.11.2025

St. Paul extols the person and work of Christ in a glorious hymn. Jesus does not simply have, but He is the image of God by whom all things visible and invisible were created. In Him, all things hold together. He is the Head of His Church, for the fullness of God dwells in Him. By His resurrection, Jesus reconciles all things to Himself. St. Paul proclaims the Gospel to the Colossians, that this i...

Colossians 1:1-14: From Darkness to Light in Christ 03.11.2025

Although St. Paul may have never visited the saints in Colossae, he writes to them with joy and thanksgiving for their faith, love, and hope. They are bearing fruit in the same Gospel that is preached throughout the world, as Epaphras has reported. Paul therefore prays that the Colossians would continue to walk in this faith as they are strengthened by God, who has transferred them from the domain...

Philippians 4:10-23: Contentment in Christ 31.10.2025

St. Paul concludes his letter to the Philippians by rejoicing over the support that they have given him during his time in prison. All the while, he reminds them of Christ Jesus as the source of contentment and strength, not only in times of prosperity, but especially in times of poverty. The Apostle has confidence that just as God has supplied his every need, so God will supply the Philippians’ e...
