Luke 18:18 – “A certain ruler asked him, ‘Good teacher, what must I do to inherit eternal life?’”
Extended Explanation
This verse introduces a conversation between Jesus and a man often referred to as the “rich young ruler” (as described in Matthew 19:22 and Mark 10:22). The man approaches Jesus with a seemingly sincere question: what must he do to inherit eternal life? This question reveals his desire for something beyond his wealth and status. He recognizes that Jesus is a spiritual authority, calling Him “Good teacher,” and asks a question that goes to the heart of human longing—how can someone secure eternal life with God?
However, the way the ruler phrases the question reveals a common misunderstanding. He asks what he must do, suggesting that he believes eternal life can be earned through good works. This sets the stage for Jesus’ response, which will challenge the man’s assumptions and expose the deeper issue in his heart—his attachment to worldly possessions and his lack of true faith.
Historical Context
During Jesus’ time, many Jews believed that righteousness and eternal life could be achieved by following the law of Moses and performing good deeds. The religious leaders, particularly the Pharisees, emphasized strict adherence to the law and viewed material blessings as signs of God’s favor. Wealthy individuals, like this ruler, were often seen as being in good standing with God because of their perceived blessings.
The man’s title as a “ruler” suggests that he was likely a leader in the synagogue or a member of the local council, giving him social and religious influence. His question shows that despite his wealth and status, he felt something was missing. This interaction reflects a larger theme in Jesus’ ministry: outward success or religious performance is not enough to enter God’s kingdom.
Theological Implications
This verse addresses a core theological question: Can eternal life be earned through human effort? The ruler’s question assumes that it can, but Jesus will soon show him that salvation is not about checking off a list of good deeds—it’s about surrendering to God completely.
Theologically, this passage highlights the doctrine of grace. Eternal life is not something we earn but something we receive through faith in God’s mercy. The ruler’s focus on doing reveals the human tendency to rely on personal achievements for righteousness. But the gospel teaches that salvation comes through trusting in God’s provision, not in our own efforts (Ephesians 2:8-9).
Literary Analysis
This verse serves as the opening to a larger dialogue where Jesus will challenge the ruler’s understanding of goodness, obedience, and the nature of salvation. The man’s respectful address to Jesus as “Good teacher” sets the tone for the conversation, but it also gives Jesus an opportunity to redefine what true goodness is—something only God possesses.
The phrase “what must I do” highlights the central tension in the story: the contrast between human effort and divine grace. The man’s question reflects a works-based mindset, which Jesus will gently correct by pointing him to the deeper issue of his heart—his attachment to worldly possessions.

What This Verse Means for Today’s Christian
This verse is a reminder that many people, even those who appear successful and religious, are searching for meaning and assurance about their eternal future. Like the rich young ruler, Christians today can be tempted to base their security on good works, moral behavior, or material blessings. But Jesus’ interaction with the ruler teaches that salvation is not about what we do but about who we trust.
For Christians, this verse challenges them to examine whether they are relying on their own efforts or on God’s grace. It also encourages believers to recognize that following Jesus often involves letting go of worldly attachments and trusting Him completely.
How This Verse Relates to a Loving God
God’s love is shown in the way Jesus patiently engages with the ruler. Instead of dismissing the man’s misunderstanding or condemning him for his misplaced confidence, Jesus meets him where he is and gently reveals the truth. God’s love doesn’t demand perfection from us—He knows that we are incapable of earning salvation on our own. Instead, His love offers salvation as a gift through Jesus Christ.
This verse also shows that God’s love is personal. The ruler’s question reflects a longing that only God can satisfy. His love reaches beyond human efforts and achievements, offering eternal life to those who humbly receive it.
How This Verse Connects to Jesus Christ
Jesus is central to the answer to the ruler’s question. The man asks what he must do to inherit eternal life, but the ultimate answer is found not in doing but in trusting Jesus. Through His death and resurrection, Jesus provided the only way for sinners to be reconciled to God and receive eternal life (John 14:6).
Jesus’ conversation with the ruler also highlights His role as a teacher who reveals the truth about God’s kingdom. While the man expected a list of good deeds, Jesus pointed him to the deeper issue—his need for a heart change and total surrender to God. This connection shows that salvation isn’t just about following rules but about following Jesus.
