Luke 5:4
What does Luke 5:4 mean?
When he had finished speaking, he said to Simon, “Put out into the deep, and let down your nets for a catch.”
The short answer
Luke 5:4 comes at the end of a long, fruitless night. Simon Peter and his partners have fished until dawn and caught nothing. Jesus has just finished teaching a crowd from Simon's boat, and now he turns to the fisherman with a simple instruction: "Put out into the deep," and let the nets down again. On its face it is fishing advice from a carpenter's son to a professional — advice that runs against everything Simon's experience tells him. The fish were not biting in the dark; they will hardly bite at midday.
But Luke has arranged his story so that this command lands differently than it would in Matthew or Mark. In Luke's Gospel, Simon already knows something about Jesus. Jesus has taught in the synagogues, his reputation has spread through the region, and he has healed Simon's own mother-in-law. So when the command comes, it is not a stranger's whim. It is a test of trust from someone Simon has real reason to trust — and Simon's answer, in the next verse, is essentially: we've tried all night, but at your word, I'll do it.
The deep water is where the story turns. The nets fill to breaking, and Simon's reaction is not triumph but awe. He falls at Jesus' knees and says, "Depart from me, for I am a sinful man." Obedience has carried him past the shallows of his own competence into an encounter with someone holy, and the abundance in the boat exposes the poverty in the man. That is where Jesus meets him — not with condemnation, but with a commission: from now on, Simon will be catching people. Luke 5:4, then, is the hinge between an ordinary working morning and a whole new life.
What scholars say
The first excerpt explains how Luke's version of the call of the fishermen differs from the other Gospels — Luke prepares the ground with Jesus' growing fame and the healing of Peter's mother-in-law before the miraculous catch. The second reflects on Peter's response, "Depart from me, for I am a sinful man," as the humility that comes from measuring ourselves against Jesus rather than against our neighbors.
“Luke’s very different version of the event is placed by him at a different point on the story line. In Luke 5:1–11 Simon, James, and John (Andrew is not mentioned) are overwhelmed by Jesus’ fish miracle and are thus moved to leave everything to follow the master. Moreover, there is preparation for the event; Mark’s story of the healing of Peter’s mother-in-law is placed by Luke before the call story (Luke 4:38–39) and Jesus is already famous for his miracles (Luke 4:37) before he challenges Peter with the announcement, “From now on you will be catching people” (Luke 5:10, REB ). Similarly, preparation is evident in John’s version; Andrew is induced to follow Jesus by the testimony of John the Baptist, and he in turn convinces his brother by announcing, “We have found the Messiah” (John 1:35–41).”
“If a man measures himself against a low standard he may be well pleased with himself. And that is precisely what many people do. They claim that they are as good as their neighbours. No doubt they are, but that is not the point. The Christian comparison is with the goodness of God as revealed in the life of Jesus; and when we compare ourselves with that there is nothing left to say except what Peter said when he realized who Jesus was, “Depart from me, for I am a sinful man, O Lord” (Luke 5: 8). If ever we feel pride in our own goodness, a moment’s comparison with the life of Jesus will reduce us to the humility we ought to have.”
What it means for you
Most of us prefer the shallows — the work we already know how to do, the standards we can comfortably meet. Luke 5:4 suggests that Jesus' call often begins exactly where our own efforts have run out: after the long night with empty nets. The invitation is to act on his word even when experience argues otherwise.
And notice where obedience leads. Simon's full nets don't make him proud; they make him honest about himself. When we measure our lives against Jesus rather than against our neighbors, self-congratulation gives way to humility — and humility, in this story, is precisely where the call to follow begins.
Luke 5 in context
Luke 5 opens with crowds pressing in to hear Jesus by the lake of Gennesaret. He borrows Simon's boat as a floating pulpit, then issues the command of verse 4. The miraculous catch follows, along with Simon's confession and Jesus' promise that he will now catch people; Simon, James, and John leave everything to follow him. The rest of the chapter continues the theme of Jesus' authority — cleansing a leper, forgiving and healing a paralyzed man, and calling Levi the tax collector — as opposition from the religious leaders begins to stir.
