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.

Matthew 2:13-23: God Brings His Son Out of Egypt 05.06.2026

God will not allow Herod to kill the Christ as a baby, so the Lord sends His angel to Joseph so that he will take Mary and Jesus to safety in Egypt. This fulfills the Word of God from Hosea 11, showing Jesus to be the people of Israel reduced to one Man. Herod’s foiled plan leads to murderous rage, and he kills the boys of Bethlehem in an attempt to kill Jesus. Even in such evil actions, however,...

Matthew 2:1-12: Who’s the Real King of the Jews? 04.06.2026

After Jesus’ birth in Bethlehem, surprise Gentile seekers come to Jerusalem looking for the newborn King of the Jews. These magi had heard the promise of the ruler’s star from the Holy Scriptures when God’s people were exiled in Babylon. Their search had a rough start when they went to the wrong place and asked the wrong king for help. Herod the Great had other plans for this boy after learning th...

Matthew 1:18-25: Joseph, Did You Know? 03.06.2026

St. Matthew explains the surprising ending to Jesus’ genealogy by relating the circumstances surrounding Jesus’ conception and birth. The Holy Spirit caused Jesus’ conception in the womb of the Virgin Mary, but Joseph did not know this. In his Christian compassion, Joseph assumed that a quiet divorce of Mary was the correct course of action, but he was wrong. The Lord sent His angel to Joseph in a...

Matthew 1:2-17: Branches of the Family Tree 02.06.2026

Matthew traces Jesus’ genealogy from Abraham through David and the Babylonian captivity. Drawing from God’s Word in 1 Chronicles, Matthew shows the way God has ordered history to keep the line of the promised Savior going until the birth of Jesus. Some surprising inclusions in the genealogy remind us that Jesus has come as the Savior for sinners of all nations. Hearing that Joseph did not beget Je...

The Reign of Heaven Stands Near - Matthew 1:1: The Genesis of Jesus 01.06.2026

Jesus called Matthew, the tax collector, to follow Him. In so doing, Jesus changed the course of Matthew’s life entirely, making him an apostle and an evangelist. Matthew’s account of Jesus’ life and ministry proclaims that Jesus has brought the reign of the heavens to earth as the fulfillment of the entire Old Testament. The book begins by introducing Jesus as the main subject. He is the Anointed...

NEW SERIES: The Reign of Heaven Stands Near 01.06.2026

“The Reign of Heaven Stands Near” is a series on Sharper Iron that studies the Gospel according to St. Matthew. The first evangelist proclaims that God has fulfilled His Old Testament promises by sending Jesus to bring the reign of the heavens among us. As the Son of David, Jesus is the gracious King we need, and as the Son of Abraham, Jesus is the blessing to all the families of the earth. Sharpe...

Psalm 150: The Hallelujah Chorus 29.05.2026

Psalm 150 brings the Psalter to a glorious conclusion. By calling upon the Church to praise the LORD, Psalm 150 calls to mind the themes of the first two psalms in which we learn to delight in the Word of God and look forward to the coming Christ. The Church praises the LORD together for His atoning sacrifice, for His work of creation, and for His victory over all enemies. The music of the Church...

Psalm 144: Blessed are the People of God 28.05.2026

David praises the LORD as his refuge and rescuer, for the LORD alone grants victory to His king and His people. This is no small wonder, that the LORD would have such regard for finite humanity, yet because of this wonder, David is bold to cry out for the LORD to come down and combat the lies of the devil with the truth of His Word. The people of God respond with a song of praise, knowing that the...

Psalm 140: The LORD is the Strength of My Salvation 27.05.2026

David cries out to the LORD for deliverance from violent men. Their violence comes primarily through their wicked words toward David and toward the LORD’s Word. Although they have laid their poisonous trap, David’s confidence remains in the LORD as his God. The LORD is the one who shields David’s head, even as the LORD also brings His fire down upon the head of the wicked. The LORD maintains justi...

Psalm 134: Benedicamus and Benediction 26.05.2026

The songs of ascents end with this brief psalm in which the people of God arrive at His holy house to bless His name. In their zeal, they arrive at night to stand watch with the ministers of His house and call upon His name in prayer. Knowing His promise to hear and answer, they continue to bless His name even before their prayer is finished. The LORD has the last word as the Creator of all things...

Psalm 132: The LORD’s Oath to David 25.05.2026

Near the end of the Songs of Ascents, the people of God call upon Him to remember David, particularly his desire to build a dwelling place for the LORD. As God’s people remember David’s desire, they share that desire to go and worship at the LORD’s footstool, and they ask that the Church would be present there together: priests, saints, and the Christ. The LORD reiterates His oath to make for Davi...

Psalm 126: Grace Isn't Just a Dream 22.05.2026

As the people of God go to worship Him, their lives are filled with joy to realize that His gracious restoration is reality. The nations see this same truth and hallow the name of the LORD, even as His own people experience the relief of His grace. God’s people pray that He would bring His restoration suddenly, so that even as they do their work in sorrow now, they will one day reap in a season of...

Psalm 121: The Almighty Creator and Keeper of All 21.05.2026

In this song of ascents, the Christian lifts his eyes toward the mountain of the house of the LORD, for that is the place where God has promised to dwell as the helper for all His people. The Christian then turns and speaks this reality to all who are joining him in worship to speak of the LORD’s help. The LORD does not fall asleep on the job, but He constantly watches over His people. Day or nigh...

Psalm 117: A Short Psalm for God’s Great Love 20.05.2026

Although Psalm 117 is the shortest psalm, its call to praise goes forth to the largest audience—all nations. The LORD, the God of Israel, has steadfast love not just toward one nation, but to all the earth. His faithful acts of salvation extend to all people and for all time. In this way, the worship of God’s people serves a missionary purpose to the nations, so that all people would join together...

Psalm 116: Gracious Is the LORD and Righteous 19.05.2026

Psalm 116 finds its place in the life of the Church both on Maundy Thursday and during the Offertory in the Divine Service. Hearing the psalm first on the lips of Jesus, we hear Him pray for deliverance from death and receive comfort in knowing that the Father has answered Jesus by delivering Him into death for our trespasses and then raising Him from the grave for our justification. This helps us...

Psalm 108: The Davidic King Rejoices 18.05.2026

Even though the prayers of David, son of Jesse, are said to have ended in Psalm 72, the Psalter records more Davidic psalms. In this way, the Psalter teaches us to look for the coming King who is both David’s son and David’s Lord. In Psalm 108, this Davidic king leads the people of God in rejoicing and giving thanks to the LORD for His steadfast love and faithfulness. He has shown His steadfast lo...

Psalm 94: Blessed by the LORD’s Discipline 15.05.2026

n Psalm 94, we cry out to the LORD as the God who takes vengeance, lest we take it ourselves against the wicked. Although the wicked afflict the weak as if God cannot see, He truly is the One who sees, hears, knows, and rebukes. The righteous receives discipline from the LORD’s hand as a blessing, knowing that following God’s Word during persecution does give rest. The LORD rises against the wicke...

Psalm 82: The Divine Judge 14.05.2026

God sits in judgment above all authorities, and He calls them to account for the injustice they show against His divine mandate. He has called them to give justice to those most in need, but when they act in ignorance of God’s command, they shake the very foundations of life. Those who would set themselves over God’s authority, whether human beings or false gods, are ultimately brought into death....

Psalm 72: God Save the King 13.05.2026

Psalm 72 prays to the LORD concerning the king to whom He gives justice and righteousness and through whom He brings justice and righteousness to His people and to the world. Although our earthly kings—even David and Solomon—fall short of the ideal God gives in His Word, the Lord Jesus does not. He is the King who perfectly cares for the poor and the needy. He is the King over all kings. He is the...

Psalm 64: Ambushed by God’s Arrows 12.05.2026

David knows that his enemies are secretly plotting against him, and so he asks God to preserve his life. These enemies set an ambush for David by their words, thinking that no one can see them. Yet, the LORD sees and springs His own ambush against these enemies that brings them to ruin by their own plots. When the nations see the LORD’s actions, they fear Him and tell what He has done, even as His...

Psalm 56: What Can Man Do to Me? 11.05.2026

As David’s enemies attack him on every side all day long, he puts his trust in God. The Word of God is the Christian’s praise and trust so that there is no need to fear the power of man, which cannot conquer God and His Word. As the enemies of God persecute His people, God personally knows each of their sufferings so that His people can be certain that God is for them and live according to His Wor...

Psalm 53: What a Fool Believes 08.05.2026

In Psalm 53, David repeats much of his prayer from Psalm 14 as he speaks about the folly that infects all mankind. Even the smartest of people show their foolishness when they live in the practical atheism that acts without the fear of God. Such folly is the state of all mankind apart from the grace of God. In that grace, God’s people cry out to him to deliver them from evil and bring His salvatio...

Psalm 45: A Royal Love Song 07.05.2026

The love song of Psalm 45 points us toward the love that exists between the King, Jesus Christ, and His Bride, the Church. As true God and true man, Jesus is the beautiful and victorious King over His enemies. He rules with true righteousness, and His people join Him in the splendor of His heavenly palace. Both Jews and Gentiles through faith rejoice in the Lord Jesus Christ, who reigns forever an...

Psalm 38: Healing from God’s Arrows 06.05.2026

David feels the consequences God has brought upon him for his sin, and so he turns to God as the only Source of rescue from such consequences. The effects of sin are both spiritual and physical, and the LORD knows them already. Prayer cries out to Him in trust that He alone can help, even when friends and foes alike provide no refuge. On the LORD alone we wait, asking Him to be near quickly for ou...

Psalm 30: God’s Gracious Reversal 05.05.2026

David praises the LORD for bringing him up and giving him healing ultimately from death. Such praise belongs not only to David but to all Christians because God’s anger over our sins quickly turns to His gracious favor for the sake of Christ. Therefore, we cry to Him for help, knowing that His promise of resurrection turns our momentary mourning into eternal singing.  Rev. Philip Hoppe, pastor at...
