Luke 5:8 records Simon Peter’s reaction to a miraculous catch of fish: he falls at Jesus’ feet and asks him to leave, because he sees himself as a sinful man standing before something holy. The verse shows a person overwhelmed by the presence of God, who responds not with pride or excitement but with humility and a sense of his own unworthiness. Peter speaks these words to Jesus, in the boat on the Sea of Galilee, right after the net fills with more fish than he and his partners can handle.
But Simon Peter, when he saw it, fell down at Jesus’ knees, saying, “Depart from me, for I am a sinful man, Lord.”

What Luke 5:8 Means
The phrase “fell down at Jesus’ knees” describes a gesture of reverence and submission. Peter is not simply stepping back in surprise. He drops to the floor of the boat, placing himself low before the one he has just recognized as more than an ordinary teacher. The posture says something before a single word is spoken.
The words “Depart from me” can sound like rejection, but they come from fear rather than dislike. Peter feels the gap between his own life and the holiness he has encountered, and he wants Jesus to leave because he believes he cannot survive being that close. Scripture elsewhere shows people responding the same way when God draws near, as though nearness to holiness exposes what is wrong in them.
Peter names himself as “a sinful man,” which is a plain, honest confession rather than a vague feeling of guilt. The verse does not promise that Peter will be comforted in that moment, and it does not say what Jesus will do next. What it does show is that an honest admission of need is where the story starts to turn toward grace, as the verses that follow make clear.
The Context of Luke 5:8
Luke wrote this Gospel as a carefully ordered account of Jesus’ life, probably for a Gentile audience and traditionally attributed to the companion of Paul who also wrote Acts. In the verses just before this scene, Peter has been fishing all night without success, and then he obeys Jesus’ instruction to let down the nets again. The large catch is a sign that Jesus’ word carries authority over the natural world, and it prompts Peter’s startled confession.
The verses that follow are essential for reading Luke 5:8 correctly. Jesus does not leave Peter, as Peter asked. Instead he says, “Don’t be afraid,” and calls him to a new task of catching people. The request to depart is answered with a call to draw closer, so the confession of sin is met with a commission rather than condemnation.
Key Phrases in Luke 5:8
Isaiah 6:5
Then I said, “Woe is me! For I am undone, because I am a man of unclean lips, and I dwell among a people of unclean lips: for my eyes have seen the King, the LORD of Armies!”
(WEB)
Isaiah responds to a vision of God’s glory with the same sense of being unclean, cry out that he is ruined, and then receives cleansing before he is sent out. The pattern of confession followed by commission mirrors what happens to Peter in the boat.
Romans 5:8
But God commends his own love toward us, in that while we were yet sinners, Christ died for us.
(WEB)
Paul writes that God demonstrated love toward people while they were still sinners. This verse explains why Peter’s confession does not lead to Jesus walking away, since the Gospel rests on God’s initiative toward those who fall short.
A Short Prayer From Luke 5:8
Lord, I come before you aware of how often I fall short of what you deserve. Like Peter, I sometimes feel that my sin makes me unfit to be near you, and I want to hide rather than stand exposed in your presence. Thank you that you do not turn away from honest confession. Help me bring my failures to you plainly, trust that you welcome me, and listen for the call you give to those you have forgiven. Amen.
