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.

Genesis 7:6-24: Water, Water Everywhere

January 23, 2026 • 54 mins
The LORD sent the flood He had promised when Noah was six hundred years old. Waters came from below and from above, and the LORD sent rain for forty days and forty nights to cover the whole earth even above the highest mountains. All flesh on the dry land died, just as the LORD had spoken. Yet, also just as the LORD had spoken, Noah and all those with him on the ark were rescued and sustained the whole time the waters prevailed upo...

Genesis 6:9-7:5: Noah Builds an Ark

January 22, 2026 • 53 mins
Noah was righteous before the LORD through faith in the LORD’s promise. In judgment, the LORD determined to send a flood to make an end of all flesh due to the corruption and violence of sin. In mercy, the LORD promised to save Noah and his family through that same flood. The LORD gave Noah precise dimensions for the ark in which he would be saved, and the LORD gave Noah instruction about the inclusion of animals on that ark for th...

Genesis 6:1-8: On the Nephilim and Noah

January 21, 2026 • 53 mins
In the generations after Adam, sin multiplied and led to growing wickedness among mankind. Even as the mysterious Nephilim capture the attention and imagination of Christians, the reality remains that violence was multiplying in the days of Noah. In mercy, the LORD promised a limit to this wickedness, even as His grief over mankind’s evil led Him to resolve to bring destruction and judgment upon His creation. Nonetheless, the Promi...

Genesis 5:1-32: The Line of the Promised Seed

January 20, 2026 • 55 mins
After the death of Abel and the departure of Cain, Moses records the genealogy of Adam through Seth. Banned from Eden, the sons of Adam inherit his sinful image and likeness. The first generations lived for incredibly long periods of time, seeing far more generations after them than we do now. This faithful line that goes through Seth believes and passes down the promises of God throughout their lifetimes. Nonetheless, sin means th...

Genesis 4:1-26: Could This Be the Savior? NO!

January 19, 2026 • 54 mins
When Adam and Eve name their first son Cain, they naturally wonder if this is the promised Offspring of the woman. Cain's faithless offering and subsequent murder of his own brother Abel quickly reveal that Cain is not the Savior. In the aftermath of Cain's sin, the LORD remains gracious to him, placing a mark upon him. Yet Cain wanders away from the LORD's presence, and his family line only departs further from the LORD. Nonethele...

Genesis 3:14-24: Sin Breaks, God Saves

January 16, 2026 • 54 mins
The LORD does not give the serpent a chance to speak. Instead, the LORD quickly speaks concerning the defeat of the devil at the hands of the Offspring of the woman. This Savior will be the Wounded Victor. As God's people wait for the Savior to come, both woman and man will experience the brokenness they have brought into the world because of their sin. Still, Adam and Eve believe the LORD's promise. He clothes them in animal skins...

Genesis 3:1-15: God Seeks His Lost Sheep

January 15, 2026 • 56 mins
Out of God’s good order described in Genesis 2, the devil begins to work disorder in Genesis 3. He cunningly tempts the woman to question God’s Word before blatantly claiming that God’s Word is evil and false. Although the woman initially recalls God’s Word, she is deceived into believing the devil’s lie, and her husband shockingly sins right along with her. The effects are disastrous, but the LORD God is quick with His mercy. He c...

Genesis 2:18-25: One Plus One Equals One

January 14, 2026 • 55 mins
The LORD says that it is not good for the man to be alone, indicating that His work of creation is not yet complete. Although Adam relates perfectly to all the animals the LORD brings before him, none of these can be the suitable helper for Adam. This helper must be the LORD's unique gift to Adam, fashioned by the LORD from Adam's own side. When Adam sees his wife, he rejoices with singing. Moses notes that this is the LORD's insti...

Genesis 2:4-17: Eden

January 13, 2026 • 54 mins
The Holy Spirit leads Moses to zoom into the account of the sixth day of creation in Genesis 2. In creating the man, the LORD does something unique. He forms dust of the ground into a man and breathes life into him. The LORD places the man into the Garden of Eden, which is a true paradise for Adam. All the gifts that sustain life are present for the man in Eden, even as the LORD grants to him the joy of work. The Word that the LORD...

Genesis 1:24-2:3: Very Good

January 12, 2026 • 52 mins
On the sixth day, God created all the land animals before crowning His work by creating humanity. God's creation of male and female is deliberate, as He creates the man and the woman in His image to exercise dominion over the rest of creation. God blesses humanity to be fruitful and fill the earth, giving them to eat the fruit of the trees. In all of this, God's creation is very good, so that He finishes His work of creation on the...

Genesis 1:6-23: Separating and Filling

January 9, 2026 • 54 mins
As God continues His creation, He does the work both of separating and filling. He separates the waters above from the waters below on the second day, and He separates the dry land and the seas on the third day. God fills the light and darkness from day one with the sun, moon, and stars on day four. God fills the expanse of day two with flying creatures on day five, and He fills the waters of day three with swimming creatures on da...

Genesis 1:1-5: One Day with the Creator

January 8, 2026 • 56 mins
The opening verses of the Bible lay forth the reality that the one true God is the Creator of all creation. Seen through the full revelation of the Holy Scriptures, these verses reveal the true God to be the Triune God. His Word does what He says as He creates light and darkness on the first day, which the context indicates to be a normal, twenty-four hour period of evening and morning. God sees that His creation is good; everythin...

Introduction to Genesis: Beginning with the Beginning

January 7, 2026 • 53 mins
You can’t understand any story without understanding its beginning, and so you can’t understand the Bible without understanding Genesis. The LORD sets the tone for all of history in the first book of Moses. As the only God, He is the Creator and Sustainer of all things. When humanity brings sin and death into His good creation, God does not leave His creation without hope, but He promises that the Offspring of the woman will come a...

NEW SERIES: In the Beginning

January 7, 2026 • 2 mins
“In the Beginning” is a series on Sharper Iron that studies Genesis. The first book of Moses sets the stage for God’s entire story of salvation. As we learn the beginning of the story, God prepares us to receive the fulfillment of the story: Jesus Christ, the Offspring of the woman who has crushed our enemy’s head.  Sharper Iron, hosted by Rev. Timothy Appel, looks at the text of Holy Scripture both in its broad context and its ...

2 Thessalonians 3:13-18: Encouraged for Good Works with Peace and Grace

December 23, 2025 • 55 mins
St. Paul encourages the Thessalonians to continue in good works without growing tired. Those who do not listen to St. Paul’s instruction must be warned as brothers, in order that their shame might lead to repentance and renewed faith. Before St. Paul finishes, he signs his letter with his own hand and blesses the Thessalonians with the peace and grace of the Lord.  Rev. Ryan Ogrodowicz, pastor at Grace Lutheran Church and School...

2 Thessalonians 3:1-12: Praying and Working

December 22, 2025 • 54 mins
As St. Paul begins to conclude his second letter to the Thessalonians, he encourages them to pray for the ongoing missionary work that he and his companions are doing. The Lord is faithful, and the apostle knows that the Lord’s Word will bear good fruit. In that confidence, he commands the Thessalonians to continue to work diligently to receive their living, just as he had done while among them. This is God’s gift, that Christians ...

2 Thessalonians 2:13-17: Chosen through Sanctification

December 19, 2025 • 54 mins
St. Paul thanks God that the Thessalonians are not among those deceived by the devil. God has made them brothers in the Church by choosing them from the beginning for salvation. This has happened through the work of the Spirit in the means of grace. The apostle thus urges the Thessalonians to stand firm in this tradition. Paul prays in confidence that God will comfort and establish the Thessalonians in His grace for every good work...

2 Thessalonians 2:1-12: Don’t Be Deceived by the Man of Lawlessness

December 18, 2025 • 52 mins
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...

2 Thessalonians 1:1-12: The Righteous Judgment of God

December 17, 2025 • 52 mins
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...

1 Thessalonians 5:23-28: Wholly Holy

December 16, 2025 • 54 mins
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...
