The Conversion of Matthew
Jesus calls Matthew — a despised tax collector and notorious sinner — to discipleship with two words: 'Follow me.' This sermon on Matthew 9:9–13 traces three movements: the sovereign, immediate call to Matthew at his tax office; the feast Matthew throws in honor of Christ, filling his table with fellow sinners; and Christ's threefold response to the Pharisees' complaint, in which he identifies himself as physician for the sin-sick, appeals to Hosea's rebuke of mere external religion, and declares his mission to call sinners to repentance. The passage insists that the power demonstrated in forgiving the paralytic avails equally for the greatest of sinners, and calls every hearer to respond as Matthew did — immediately, wholly, and with joy.
The First Murder
Genesis 4:1–16 records the first fratricide in human history, and this exposition reads that account as a theological document revealing the rapid escalation of sin from the fall in chapter 3. Cain's rejection is traced not to his vocation as a farmer but to his faithlessness — Abel's offering was accepted because it was offered in faith (Hebrews 11:4), while Cain's externalism and lack of genuine faith made his sacrifice an abomination. God's patient, gracious overtures to Cain before the murder underscore divine long-suffering, while Cain's murder of Abel illustrates the antithesis of Genesis 3:15 — the seed of the serpent attacking the seed of the woman — and the sermon closes by setting the blood of Abel, which cries out for condemnation, against the blood of Jesus, which speaks forgiveness.
The Calling of Matthew
The calling of Matthew in Matthew 9:9–13 is not merely a biographical interlude but a deliberate theological display of Christ's authority to save notorious sinners. Matthew's own spare account of his conversion — omitting Luke's detail that 'he left all' — directs every eye to the power of the Son of Man rather than to the sacrifice of the disciple. The sermon traces Jesus's three-fold response to the Pharisees' complaint — proverb, prophet, and purpose — showing that the physician goes to the sick, that Hosea's call for mercy over mere cultic observance still indicts externalism, and that Christ's stated mission is to call sinners, not the self-righteous, to repentance. The hearer is exhorted to respond as Matthew did: immediately, totally, with thankfulness, and with a desire to bring others to the Savior.
From Fasting to Feasting
Zechariah 8 answers the question posed in chapter 7 — whether the returning exiles should continue their fasting commemorating the exile — by redirecting attention from empty ritualism to the sovereign blessing of God under the Messianic reign of Christ. The chapter unfolds in five movements: the restoration of Zion to God's favor, an exhortation to persevere in the work of building, a call to sincere internal religion, the definitive answer that exile-fasts are transformed into feasts, and the promise of Gentile inclusion in covenant blessing. The fulfillment of these promises is grounded not in human faithfulness but in the zeal of Jehovah himself, whose determination to do good to his people drives the advance of the Gospel from Pentecost to the present day. The sermon closes with a call to carry Zechariah's vision of the nations streaming to Christ into the prayer closet and into the practical life of the church.
A Question About Fasting
Zechariah 7 records a delegation from Bethel arriving in Jerusalem to ask the priests whether the fasts commemorating the destruction of the temple should continue now that the temple is being rebuilt. Rather than answering the calendar question directly, God through Zechariah exposes the deeper problem: these fasts had been observed as empty external rites, not as genuine heart devotion to God. The sermon works through the text in three movements — the question posed, the divine answer exposing formalism, and the necessity of genuine religion marked by justice, mercy, and compassion — and closes with a call to believe the gospel before the heart becomes too hardened to hear.
