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.

NEW SERIES: The Post-Exilic Prophets 04.07.2024

"The Post-Exilic Prophets” is a series on Sharper Iron that goes through the books of Haggai, Zechariah, and Malachi.

Esther 9:20-10:3: The Feast of Purim 03.07.2024

In order to remember and celebrate God’s deliverance of His people, Mordecai calls for the yearly celebration of the feast of Purim. The feast’s name is a reminder of the lots that Haman had cast to find the right day to destroy God’s people, which God reversed to bring about the day He delivered His people. As the hectic events settle down, King Ahasuerus institutes a new tax as an indication tha...

Esther 9:1-19: The Deliverance of God’s People 02.07.2024

When the thirteenth day of the twelfth month arrives, two contradictory Persian decrees are both legal. On the one hand, the enemies of God’s people are allowed to slaughter them; on the other hand, God’s people are allowed to defend themselves. Through a divine reversal, the people of God ably defend themselves from those who are trying to kill them. Haman’s sons particularly are executed, and th...

Esther 8:1-17: Mordecai’s Decree 01.07.2024

After Haman’s execution, Ahasuerus gives Haman’s house to Esther, and he gives his signet ring to Mordecai. Esther risks going before the king a second time, and he extends his scepter to her again. She asks for a second decree to be made to counteract the first, since the first could not be repealed under Persian law. With the king’s authority, Mordecai writes a decree that allows the people of G...

Esther 6:14-7:10: Haman’s Cross 28.06.2024

Immediately after Haman’s shame at being forced to honor Mordecai, he is taken to Queen Esther’s second feast. There Esther reveals her request to Ahasuerus: she asks that he spare her and her people from destruction. When the king asks who is behind such wickedness, Esther names Haman as the foe. As Haman realizes his imminent demise, he pleads for his life from Queen Esther, but the king sees it...

Esther 6:1-13: And the King’s Honor Goes To... 27.06.2024

The king attempts to secure his sleeplessness by having the book of memorable deeds read to him. When Ahasuerus learns that Mordecai has received no honor for the way he had saved the king from a homicidal conspiracy, the king asks Haman for his counsel. Confident that the king means to honor him, Haman recommends the highest accolades. To Haman’s shame, he is forced to honor the man he hates, Mor...

Esther 5:1-14: The Queen's First Feast 26.06.2024

After three days and nights of fasting, Esther goes before the king without an invitation. He spares her life by extending his scepter to her, and he tells Esther to present her request. Using her God-given wisdom, Esther simply invites both the king and Haman to her feast that night. There, she promises that she will present her request when they come to her second feast the following evening. Ha...

Esther 4:1-17: Faithfully Facing the Unknown 25.06.2024

In response to Haman’s wicked plot, Mordecai and the people of God throughout Persia mourn and repent, as seen in their outward appearance and actions.

As they converse via messengers, Mordecai makes Esther aware of what Haman has decreed against the people of God and warns her that she will not escape in the palace...

Esther 3:1-15: Haman’s Plot 24.06.2024

When King Ahasuerus elevates Haman above all other Persian officials, Mordecai refuses to bow before Haman, likely due to religious realities. In fury, Haman begins to plot to destroy not only Mordecai but the entire people of God to which Mordecai belongs. At this point, however, Haman’s fury does not overwhelm him. He patiently casts lots to find just the right date for his evil plan. When the l...

Esther 2:1-23: The Bachelor, Susa Edition 21.06.2024

After a delay due to military campaigns, King Ahasuerus remembers what had happened with Vashti and decides to find a new prized queen. Among those taken into the king’s palace was a young Judean woman, Esther, an orphan who had been raised by her cousin, Mordecai. Mordecai helps Esther navigate a terribly difficult situation. Eventually, Esther is chosen as queen. As Mordecai continues to stay in...

Esther 1:1-22: Ain’t No Party Like a Persian Party 20.06.2024

When the king does not know what to do, his advisors tell him to issue a proclamation putting Vashti in her place, lest other Persian wives behave s...

NEW SERIES: For Such a Time As This 20.06.2024

"For Such a Time As This” is a series on Sharper Iron that goes through the book of Esther. Although God is never explicitly named in the book of Esther, He remains the One who directs all the events of the book. Happenings that seem coincidence, chance, or luck are truly God at work. He puts Mordecai and Esther in the right places and moments to work through them to deliver His people.   Sharper...

Nehemiah 13:1-30: Nehemiah’s Reformation 19.06.2024

After Nehemiah had gone back to the court of King Artaxerxes for a time, he returned to Jerusalem to find God’s people in need of continued instruction and correction. Although they had promised to remain faithful to the LORD by caring for His house, observing the Sabbath, and avoiding intermarriage with idolaters, God’s people had fallen into sin in each of those areas. As a faithful leader, Nehe...

Nehemiah 12:1-47: The Dedication of Jerusalem’s Wall 18.06.2024

Another list of people who had returned Jerusalem includes information about the roles they fulfilled, especially within the worship life of God’s people. Because the rebuilding of the wall of Jerusalem was more than a secular construction project, the people of God dedicate the completed work with singing and great joy. Multiple choirs lead the people in worshipping God, and their joyful singing...

Nehemiah 11:1-36: The City Directory of Jerusalem 17.06.2024

Although Jerusalem’s walls had been rebuilt, few people were living in the city itself. The leaders first moved into Jerusalem, and the rest of the people willingly participated in the casting of lots to allow the LORD to determine the rest of the city’s residents. The list of the people who moved into Jerusalem, as well as those who remained in the villages surrounding the city, provided physical...

Nehemiah 10:1-39: Returned Exiles Make Their Confirmation Vows 14.06.2024

As the people prepare to renew the covenant with the LORD, they seal their names before Him. The clergy and the laity, the leaders and the people, all join to enter into a curse and an oath to walk in God’s Law given to Moses. In view of their history that led to their exile in the first place, the people particularly make promises concerning intermarriage with idolaters, keeping the Sabbath day,...

Nehemiah 9:1-38: Confession in View of God’s Mercy 13.06.2024

Having heard the Word of God, the people gathered in Jerusalem join in prayer to the LORD. They bless the LORD’s name for His acts of mercy throughout their history. He showed mercy in making a covenant with Abraham. He showed mercy in delivering Israel from Egypt. He showed mercy by providing for their well-being in the wilderness. Even when Israel rebelled against the LORD by worshiping a golden...

Nehemiah 8:1-18: The Joy of the LORD Is Your Strength 12.06.2024

With the walls of Jerusalem complete, the people of God now gather to hear the Word of God. Ezra the scribe and many helpers provided that the Word of God be read and proclaimed to the people from early morning until midday. As the people gave their attention to all that God said, Nehemiah and the Levites encouraged the people to rejoice. Not only did the people listen to the Word of God, they als...

Nehemiah 7:5-73: List of Returned Exiles, Take 2 11.06.2024

As Nehemiah prepares to take a census of the people of Judah in preparation for people to move into Jerusalem, he finds the record of those who had returned at the edict of Cyrus almost 100 years ago. Although the list had been recorded previously in Ezra 2, the list is recorded again in this place as a reminder of the faithfulness of previous generations. Now that the wall of Jerusalem is complet...

Nehemiah 6:1-7:4: Jerusalem’s Wall Is Finished 10.06.2024

As the construction of the wall of Jerusalem nears completion, opposition against Nehemiah and the people of God grows. Nehemiah wisely recognizes the plots of his enemies and refuses to yield to their threats and intimidation. Even though the enemies of God’s people find allies within Judah, Nehemiah refuses to fall into sin and prays that the LORD would remember his enemies. By the LORD’s grace,...

Nehemiah 5:1-19: Care and Generosity within the Household of Faith 07.06.2024

Trouble for the people of God never comes only from without; trouble also arises from within. In Nehemiah’s time, even as the wall of Jerusalem was under construction, members of God’s people were oppressing the poor in Israel through the exaction of usury. Nehemiah takes time away from the important building project to deal with this even-more-important matter of spiritual care. He calls the nobl...

Nehemiah 4:1-23: A Shovel in One Hand and a Sword in the Other 06.06.2024

The work on Jerusalem’s walls brings anger and mockery from the opponents of the people of God. Nehemiah and the people of Judah draw strength from God through prayer, and they refuse to stop. Such a faithful response brings about plans for a secret attack by the opposition, and morale in Israel begins to waver. Nehemiah responds with both prayer and action, trusting that God will fight for the pe...

Nehemiah 3:1-32: Workers on the Wall 05.06.2024

After Nehemiah’s inspection of the wall, the people begin to work. The list of workers shows the willingness of God’s people to do the labor needed. Although the areas of expertise of the workers varied, together they recognized the need and participated in the construction of the walls of Jerusalem. Although the various locations of gates and sections of the wall may not be known to us exactly, t...

Nehemiah 2:1-20: Faith Active in Prayer and Prudence 04.06.2024

Nehemiah spends three months in prayer and preparation for the LORD gives him an opportunity to present his request to Artaxerxes. When the moment arrives, Nehemiah utters yet another brief prayer and asks Artaxerxes to send him to Jerusalem. God answers Nehemiah’s prayer as Artaxerxes agrees. When Nehemiah returns to Jerusalem, he discreetly inspects the walls of Jerusalem before exercising prude...

Nehemiah 1:1-11: The Faithful Cupbearer Prays 03.06.2024

Like the book of Ezra, the book of Nehemiah details both the physical restoration of the city of Jerusalem and the spiritual restoration of the faith of God’s people. Nehemiah, the cupbearer to King Artaxerxes of Persia, receives word that the city walls of Jerusalem remain in ruins, even many years after the temple had been rebuilt. Recognizing the shame of this reality, Nehemiah turns to the LOR...
