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.

Episodes

Hosea 6:11-7:16: The Sickness Grows 26.08.2025

Even as the LORD attempts to heal His people, more of Israel's disease becomes apparent. Hosea speaks about the sin in Israel with vivid images.  As the heat of an oven that leavens dough before the blazing fire bakes it, so the treachery in Israel grows until it blazes with destruction, even as the people fail to call upon the LORD. As an aging man tragically does not realize the loss of his facu...

Hosea 6:1-10: Fleeting Repentance and Insincere Worship 25.08.2025

Having heard the LORD’s call to repentance, Hosea desires to lead the people back to their God. He calls them to return to the LORD in the certain faith that the LORD raises the dead and forgives sinners. Nonetheless, the people of Israel only display temporary repentance and hypocritical faith. Despite the preaching of the prophets and God’s available and abundant grace, the wickedness in Israel...

Hosea 5:1-15: Idolatry Won’t Cure Sin’s Wound 22.08.2025

The LORD calls the leaders of His people to account. Although Israel does not know Him, He knows Israel and sees the prideful idolatry that infects both the northern and southern kingdoms. The LORD says that the warning trumpet must sound, for He is bringing His judgment, slowly but surely. As Israel continues to look for help in the wrong places, the LORD promises to return to His place until His...

Hosea 4:1-19: Destructive Ignorance 21.08.2025

Through Hosea, the LORD indicts His people for their lack of faithfulness, steadfast love, and knowledge of Him. The last of those three charges takes center stage first. The priests of Israel have failed to teach the people to know the LORD truly, and so the whole land suffers. The idolatry of Israel, led by the priests, has failed to fulfill any of their needs, even as the people foolishly worsh...

Hosea 2:14-3:5: A Faithful Husband to a Faithless Bride 20.08.2025

Hosea’s preaching takes a Gospel turn as the LORD promises to woo Israel anew as His bride. No longer will they call upon Him in idolatrous worship, but they will call upon Him as their Husband according to His holy name. In this wedding between God and His people, He invites them to dwell with Him as He once dwelt with Adam and Eve in Eden. The LORD’s command that Hosea bring back Gomer, despite...

Hosea 2:1-13: Israel’s Spiritual Adultery 19.08.2025

As Hosea preaches from his marriage to an adulterous woman, he speaks against the spiritual adultery Israel has committed against the LORD by their idolatry. Although the LORD was always the source of all Israel’s good gifts, they failed to realize this and foolishly looked to Baal for blessing. In response, the LORD promises that He will take such blessings away and make the Promised Land a wilde...

Hosea 1:1-11: Names that Preach 18.08.2025

The LORD called Hosea to preach to the northern kingdom, Israel, during times that were prosperous economically but horrific theologically. The first part of Hosea’s book centers on the LORD’s command for Hosea to marry a wife of whoredom, Gomer. Through Hosea’s marriage, the LORD provides a living sermon of the relationship between Himself and Israel. The names given to the three children of Hose...

NEW SERIES: Majoring in the Minors 18.08.2025

“Majoring in the Minors” is a mini-series on Sharper Iron that goes through the books of Hosea, Joel, Jonah, Micah, and Nahum. Although the books of these prophets are shorter, the Word of God they preached was important in the years leading up to the coming of the Christ, and that Word remains important for the Church today. Just as we still need to listen to their call to repentance over our ido...

Psalm 148: The Song of All Creation 15.08.2025

As the Psalter draws to a close with a grand Hallelujah Chorus, Psalm 148 calls upon all creation to join together to praise the LORD. The praise starts with the heavens and the heavenly creatures. These are not to be worshiped, but rather, they join together in worship to the Creator who continues to sustain them by His Word. The praise of the LORD continues on the earth among all earthly creatur...

Psalm 142: The LORD Knows My Way 14.08.2025

Hiding from Saul in a cave, David lays his complaint fully before the LORD. He prays in confidence that although his enemies have laid a trap for him, the LORD’s knowledge of his way will prevail. When no one else seems to notice David as he is in the midst of great trouble, the LORD brings David out of the prison so that he is not actually alone. The LORD surrounds David with His righteous ones,...

Psalm 135: God’s Gracious Will Done in Heaven and on Earth 13.08.2025

In Psalm 135, the worshipers who have been ascending to the LORD’s house on Zion sing their praises to Him. All of the priests and the servants of the LORD are called upon to praise the LORD as the only true God who accomplishes His will of salvation. His praise sounds forth throughout all creation, even as His people know Him as the true God who delivered them from their enemies. All idols are no...

Psalm 131: Hearts Quietly Lifted to the LORD 12.08.2025

Psalm 131 finds its home in the psalms of ascent as a short text that takes a long time to learn. David refuses to lift his heart or eyes in pride above the LORD, recognizing that those good things which the LORD has given in His Word are a refuge for him. In God’s Word, David and all Christians have a quiet place of refuge and nourishment. In the LORD, Christians have a hope that does not disappo...

Psalm 124: The LORD Is on Our Side 11.08.2025

Psalm 124 is among the psalms of ascent, used by worshipers going to the temple in Jerusalem. Singing antiphonally with a leader, those who come to worship the LORD bless His name for His rescue from those who would have swallowed them up and washed them away. The LORD has sprung the trap that was set against His people, for as the Creator of all things, He comes to help His people. In our Lord Je...

Psalm 113: Our God Stoops Low to Heal 08.08.2025

Psalm 113 is the first psalm in the Egyptian Hallel, which was used during the Passover celebration. The servants of the LORD are called to praise Him at all times and in all places. He is enthroned over His entire creation so that no one at all is like Him. In His almighty power, He shows incredible mercy, lifting up the poor and the needy and giving children to the barren. All of this He has acc...

Psalm 101: A King Needs Integrity of Heart 07.08.2025

Knowing the mercy of the LORD, who reigns as King over all creation, David sings the LORD’s praises and meditates on His blameless way. From that faith, David vows to reign with integrity of heart by looking to the LORD alone and rejecting the path of evil endorsed by the devil and the world. The slanderous, the arrogant, and the false have no place in David’s reign, regardless of their outward ap...

Psalm 99: Holy, Holy, Holy Is the LORD, the King 06.08.2025

The LORD reigns as the transcendent King over all the earth and all the nations, yet He comes near to His people as He rules from the place where He has promised to dwell. The peoples are called to praise Him for His just and righteous rule. He is the holy God who intends for His holiness to bless us. Moses, Aaron, and Samuel all experienced the blessing of God’s holiness as they called upon Him,...

Psalm 93: The LORD Reigns Over the Waters 05.08.2025

Just as the Anointed One of the LORD reigns in Psalm 2, so the LORD Himself reigns in Psalm 93, pointing forward to the incarnation of the Word in the person of Jesus Christ. Though the kings in the line of David have not always been faithful, the LORD is the faithful King. He has established His throne forever for the sake of His people. Although the waters may roar against the LORD, He is their...

Psalm 89: Remember, O LORD, Your Promise to David 04.08.2025

Psalm 89 begins by praying to the LORD as the incomparable Creator of all things. He stills the mightiest forces in all creation by His mighty hand, and His people are blessed. That blessedness is seen especially in the LORD’s steadfast promises to David and his son. Yet the people of God lament that the line of David seems to have withered under God’s judgment, and so they pray that the LORD woul...

Psalm 80: Stir Up Your Power, O Lord, and Come 01.08.2025

In Psalm 80, the people of God cry out to Him to stir up His might to come and save them. Calling upon God as the Shepherd of Israel who is enthroned in His temple, the people ask that God would turn them back to Himself and that He would turn His face toward them. The psalm recounts the history of God’s faithfulness to Israel as His vineyard and God’s judgment against Israel for their idolatry. T...

Psalm 73: If Thou, Lord, Wert Not Near Me 31.07.2025

Asaph knows that God is good to His people, and yet the prosperity of the wicked almost leads him to stumble from the faith. Even as he recognizes the wickedness of the arrogant, he sees that their riches increase, and he wonders if faith in the LORD is worth it. He holds his tongue from leading others astray and turns instead to the LORD’s saving presence in His sanctuary. There, he recalls that...

Psalm 67: Mission and Thanksgiving 30.07.2025

Psalm 67 leads us to pray that God would give His people the blessing given to Aaron for the purpose of making God’s salvation known among all nations. All peoples are called upon to praise the one true God who is the righteous Judge over all the earth. In His righteousness, He brings salvation so that the peoples praise Him for all His bounty, both physical and spiritual. All the ends of the eart...

Psalm 57: God Is Exalted and Glorious Above All 29.07.2025

As David hid from Saul in a cave, he cried out to God confidently for mercy. Even before God answered his prayer, David knew that the LORD would show steadfast love and faithfulness to rescue him. Though David’s enemies surrounded him, the glory of God that is over all the earth gave David courage. He knew that his enemies would fall into their own trap, and so he praised God even before the dange...

Psalm 50: True Faith in the God Who Speaks 28.07.2025

Psalm 50 begins with the LORD summoning His people before Him for a trial. He does not keep silence, but calls out so that His people will listen to Him. He acknowledges that they have made sacrifices continually, but they have done so without faith, as if God needed something from them. Instead, God calls His people to offer their sacrifices with thanksgiving, to keep their vows to Him with faith...

Psalms 42 and 43: A Hopeful Refrain 25.07.2025

Psalms 42 and 43 share a common refrain in which the psalmist recalls the comfort of the hope he has in God, his salvation, even in the midst of terrible turmoil. He thirsts to be with God, and yet, his enemies question where his God even is. He cries out to God who, at times, seems to have forgotten him. He prays that God would answer with light and truth and so bring him back to the altar of God...

Psalm 37: Fret Not 24.07.2025

Through use of an acrostic poem, David meditates on the reality that the LORD is faithful to His promises. Those who wait on Him have no need to worry over the wicked and their wickedness. When the righteous see the prosperity of the evil, falling into the same way of evil helps nothing; continued delight in the LORD who gives His children an eternal inheritance is the only answer. The wicked ulti...
