Luke 3:10 records the crowd coming to John the Baptist and asking what they should actually do in response to his call to repentance. The question is practical and urgent: they have heard the warning about God’s coming judgment, and now they want to know what a changed life looks like day to day. John is the speaker’s counterpart in the question, since the crowd is the one asking, and John’s answer in the verses that follow is aimed at ordinary people who came out to the Jordan River to be baptized.
The multitudes asked him, “What then must we do?”

What Luke 3:10 Means
The phrase “the multitudes” points to a large, mixed group of people drawn to John by his preaching in the wilderness. They are not a single category of believers or a religious elite. They are simply people who have been stirred up and now feel the need to respond. Their question, “What then must we do?”, uses the word “then” to link back to John’s sharp words in the verses just before, where he warned against empty religious confidence and called for fruit that matches repentance.
The question does not ask how to earn God’s favor in some abstract sense. It asks for specific action. That is why the verse is useful: it shows people wanting to move from feeling convicted to doing something concrete. The verse does not itself promise rewards or guarantee outcomes. It records a sincere question, and the answer that follows in Luke 3:11 to 14 gives examples of what that response looks like in real settings.
The Context of Luke 3:10
Luke’s Gospel was written to a largely Gentile audience, possibly a man named Theophilus, and the author presents himself as one who carefully investigated the events of Jesus’ life and its background. Traditionally the author is identified as Luke, a companion of Paul, and that is the view most readers have held. The book opens with careful historical framing, placing John’s ministry within the reign of Tiberius Caesar and the rulers of the region, which gives the story a grounded, public quality.
Just before the verse, John has called the crowd a brood of vipers and warned them to produce fruit worthy of repentance, not to rely on being descendants of Abraham. Just after, the crowd’s question is answered with examples: sharing clothing and food, collecting taxes honestly, and treating others fairly. Read in this setting, Luke 3:10 is not a question about rituals or status. It is the moment when a warning about inner change turns toward everyday conduct.
Key Phrases in Luke 3:10
Matthew 3:8
Therefore produce fruit worthy of repentance!
(WEB)
Matthew records a parallel account of John’s preaching and his call to produce fruit in keeping with repentance. Reading it alongside Luke 3:10 shows how the same message was remembered across the Gospels, reinforcing that real change is visible in the life that follows.
Micah 6:8
He has shown you, O man, what is good. What does the LORD require of you, but to act justly, to love mercy, and to walk humbly with your God?
(WEB)
Micah offers an older summary of what God looks for in a person: justice, kindness, and humble walking with God. It fits well with Luke 3:10 because it describes the practical character behind the question of what to do.
A Short Prayer From Luke 3:10
Lord, when I feel the pull to change but don’t know where to begin, help me to ask honestly and then listen for your direction. Show me one concrete step I can take today, whether in how I treat the people around me, how I handle my work, or how I use what I have. Give me the humility of the crowd at the Jordan, willing to admit I need to change and open to your guidance. Let my choices grow out of a heart that is turning toward you, one faithful action at a time. Amen.
