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.

St. Paul turns the Thessalonians’ attention to the right teaching concerning the coming of the Lord Jesus. The apostle does not want his beloved congregation to be deceived by any source, and so he warns them concerning the coming of the man of lawlessness, who will attempt to usurp the place of Christ in the Church. Such a spirit of rebellion is already at work, but St. Paul urges confidence on the part of the Church by proclaimin...

St. Paul and his companions begin the second letter to the Thessalonians in grace and peace from the one true God. It is right for them to be thankful for this Christian congregation because their faith is growing and their love is increasing. This remains true even as they endure persecution and affliction for the sake of Christ. The apostle assures the Thessalonians that this does not mean that they have been separated from God’s...

St. Paul concludes his first letter to the Thessalonians by commending them to the God of peace, who alone makes His people holy until the coming of the Lord Jesus Christ. Just as conversion to the Christian faith is God’s work, so is keeping us in the Christian faith God’s work, and St. Paul expresses confidence that God will do this for the Thessalonians. He asks the Thessalonians to pray for him and his team and to bring his aff...

St. Paul gives further instructions to his brothers in Christ in Thessalonica as to what their lives should look like as Christians waiting for the Last Day. Hearers respect and esteem their pastors as those men work diligently to proclaim the Gospel. Peace reigns in the congregation as those who are weak and faint are treated with patience. Forgiveness trumps vengeance. Joy, prayer, and thanksgiving abound. All of these gifts char...

St. Paul reminds the Thessalonians about the coming day of the Lord. No one knows the date. Christ’s return will be sudden, and those who have sought security apart from Him will go to destruction. Christians, however, do not live in that darkness. Christ has called us into His light, and so we live in alert, wakeful sobriety produced by attention to the Lord’s Word. His gifts of faith, love, and hope protect us from the devil’s at...

St. Paul teaches concerning the resurrection of the body so that the Thessalonians will be able to mourn with hope for those who have fallen asleep in Christ. The foundation of this certainty is the death and resurrection of Jesus, through whom God will raise the dead. The apostolic teaching on the matter comes from the Lord Himself who will return visibly and publicly on the Last Day. On that Day, those who have already died will ...

St. Paul commends the Thessalonians to continued brotherly love for each other, as they have already been taught through the Word of God. Such love should be expressed more and more not only in their local congregation, but throughout their region. In so doing, the Christian goal is not pride, but rather quiet and diligent work in service of the neighbor. This both follows the example that Paul set and gives a truthful witness to t...

St. Paul encourages the Thessalonians to abound more and more in the way that they are walking according to the word of God. His will for their lives is holiness, which He gives to His people. Such holiness manifests itself in the lives of Christians through chastity, purity, and self-control. Because we know God, we do not live as the pagans do. Instead, we live according to His call through the Gospel.

He returns thanks to God in his ongoing prayers for the Thessalonians in his time away from them, even as he longs to return to them. Paul commends the Thessalonians into the care of the Triune God, praying that He would continue to make the love of the Thessalonians abound and establi...

Paul tells the Thessalonians of his great desire to return to see them in person and notes that Satan is the one who hindered such a joyful reunion. As Paul looks forward to the Last Day, he knows that the Thessalonians are a source of great joy. That led him to send Timothy to them to check on them, even when Paul couldn’t go personally. His purpose was to help the Thessalonians remain steadfast in persecution. Still today, Satan ...

Paul gives thanks for the way the Thessalonians received his preaching as the very Word of God. That Word has brought forth fruit in Thessalonica as the congregation there was joined to the rest of the Church in suffering for the sake of Christ. Paul encourages the Thessalonians to remain faithful to the Lord even in suffering, knowing that God will bring justice and vindication on the Last Day to those who oppose Him.

Paul reminds the Thessalonians of the time he and his companions spent there. Despite previous opposition in Philippi and persecution in Thessalonica, Paul labored diligently to bring the Gospel to the Thessalonians, not to please man, but to please God. Even as he toiled night and day, he did so with the same care and affection that parents show their children. As the Thessalonians recall the way Paul ministered to them, they are ...

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 throughout the world, as they rememb...

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 was received with great joy, but t...

“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 the Last Day.

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!

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, and His steadfast love and faithfuln...

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, Jesus. We pray that He would bless u...

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 the Word fruitful in our lives now so...

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 Lord’s army through the struggles of ...
