Acts 13:24-25 Commentary: John’s Preparation for the Messiah

Paul is preaching in the synagogue at Pisidian Antioch, a mixed audience of Jews and God-fearers. He traces salvation history from the patriarchs through the judges, kings, and David, landing on John the Baptist as the immediate forerunner of the promised Savior. John’s ministry was set against the backdrop of Jewish messianic expectation in the first century, many Jews believed the age of the Messiah was near, and various would-be deliverers had arisen. John stood out because he did not claim to be the Christ, but pointed to another. His baptism of repentance (μετάνοια, a change of mind and life) was unprecedented: unlike the repeated Levitical washings, it was a one-time public commitment signaling a new beginning. This baptism ‘before the face of his entrance’, Christ’s public ministry, was the way God prepared a people ready to receive their King. Paul’s recounting of John’s words, especially the sandal-untie saying, would have resonated powerfully. Loosing a teacher’s sandal was the lowest task, typically done by servants. John’s claim that he was not worthy to do even that for the coming One communicated both Christ’s supreme dignity and his own proper place. In a synagogue service where the prophets were read regularly, hearing this from a respected preacher like Paul would root Jesus firmly in God’s unfolding plan.

The consulted sources note a minor textual variation in verse 25. The Cambridge Bible observes that the oldest manuscripts read ‘What think ye that I am?’ instead of ‘Whom think ye that I am?’ The variant does not affect the meaning; both forms present John’s question as a refutation of the crowd’s speculation that he might be the Messiah. No other significant variants are discussed by the commentaries provided.

From the early church onward, John the Baptist has been honored as the forerunner who prepared the way for Christ. This passage, with its double emphasis on repentance and John’s self-effacing testimony, was frequently cited in catechetical and baptismal preaching. In the Latin tradition, phrases from these verses influenced prayers used during Advent, a season of preparation parallel to John’s ministry. Protestant reformers like Calvin and Wesley drew on Acts 13:24, 25 to argue that even the most faithful ministers must always point away from themselves to Christ. The image of John ‘fulfilling his course’ has also been used as a model for Christian endurance, summed up in Paul’s later words: ‘I have fought the good fight, I have finished the course’ (2 Timothy 4:7). Across traditions, John’s humility, calling himself unworthy to untie Jesus’ sandals, remains a standard of genuine discipleship.

Three-point outline

1. Preparation through repentance. John’s preaching of a baptism of repentance prepared hearts by calling Israel to turn from sin and look for the coming One.
2. Humility that points away. John refused the title of Messiah: ‘I am not he.’ His honest self-assessment directed all attention to Jesus.
3. The coming One is worthy of total honor. John’s confession, unworthy to untie even his sandals, shows that Jesus stands above every human leader and deserves our complete trust.

Five-point outline

1. The forerunner’s role: John came before Christ to announce and prepare.
2. The message of repentance: He called all Israel to a change of heart and life.
3. The honest confession: ‘I am not the Messiah’, a vital clarification.
4. The exaltation of Christ: ‘One comes after me… whose sandals I am not worthy to untie.’
5. The invitation: Paul’s sermon continues: ‘the word of this salvation is sent out to you’ (v.26). The prepared heart now welcomes the Savior.

Illustration hooks

• A warm-up act. Think of a concert where the opening band prepares the crowd for the main act. The opening band gets the audience excited, then steps aside. John did exactly that, he stirred expectation, then pointed to Jesus.
• A good referral. When someone gives you a glowing recommendation for a doctor, you trust that doctor even before meeting them. John’s testimony gave Israel a reason to trust Jesus before he appeared publicly.
• A short race. John’s ministry lasted perhaps only a few years, a ‘course’ or sprint. His example shows that even a brief season of faithful service can have lasting impact when it points to Christ.

Questions your congregation is asking

• Why did John’s baptism matter if it wasn’t Christian baptism?
• How can we prepare the way for Jesus in the lives of others today?
• What does it look like to humbly step aside so that Christ gets the attention?

These two verses are a compact summary of John the Baptist’s role. He preached repentance, refused to take credit for himself, and pointed to the greater One coming after him. Paul uses this history to show that Jesus is the fulfillment of everything God had been doing through the prophets. Consider how John’s example shapes our own calling to point others to Christ.

Discussion questions

1. What does it tell us about God’s plan that he sent a forerunner to prepare the way for Jesus?
2. John’s message was ‘the baptism of repentance.’ In what ways does repentance prepare someone to receive Christ?
3. When John said, ‘I am not he,’ he clearly rejected the identity of Messiah. Why is it important that John did so explicitly?
4. The phrase ‘fulfilling his course’ (dromos) suggests a race. What aspects of John’s life fit that metaphor? What aspects of your own life’s calling might also be like a race?
5. John described himself as unworthy to untie Jesus’ sandals. How does his humility challenge our culture’s emphasis on self-promotion?
6. How did John’s testimony make it easier for the first hearers of Paul’s sermon to believe in Jesus?
7. What is one way this week you can point others to Jesus rather than drawing attention to yourself?
