How does Luke 18:18 challenge the concept of salvation by works? Canonical Location and Synopsis Luke 18:18 : “Then a certain ruler asked Him, ‘Good Teacher, what must I do to inherit eternal life?’” The verse introduces the well-known encounter between Jesus and the “rich young ruler” (cf. Matthew 19:16-22; Mark 10:17-22). A socially prominent Jew approaches Jesus with a works-oriented question: “What must I do…?” The episode functions as a narrative exposition of the impossibility of earning salvation and the absolute necessity of divine grace. Immediate Literary Setting Verses 15-17 depict Jesus blessing helpless infants, saying, “Whoever does not receive the kingdom of God like a little child will never enter it” (v. 17). Luke deliberately juxtaposes child-like dependence with the ruler’s achievement-oriented inquiry, heightening the contrast between faith and works. Jesus’ Initial Rebuke of “Good” “Why do you call Me good? No one is good except God alone” (v. 19). 1. Jesus redirects the ruler’s attention from human virtue to divine perfection, exposing the faulty premise that a merely human agent can perform sufficient works. 2. The statement echoes Psalm 14:3 and 53:3—“There is no one who does good”—and prepares the ground for sola gratia (grace alone). Citation of the Decalogue and the Missing Command Jesus lists commandments five through nine (v. 20) but omits the tenth (coveting) and the first four (God-ward). The omission is strategic: • Covetousness is the sin that will shortly be unmasked (v. 23). • The God-ward commands center on wholehearted love and worship, which the ruler lacks. Christ’s selective citation allows the man to profess external compliance (“All these I have kept since my youth,” v. 21) while leaving the heart exposed. The Impossible Demand “Sell all you have, distribute to the poor…then come, follow Me” (v. 22). The call is not a universal poverty mandate; it is the diagnostic that uncovers the ruler’s idol. Perfect law-keeping demands perfect love of God and neighbor (Deuteronomy 6:5; Leviticus 19:18). By highlighting the idol of wealth, Jesus proves the man’s inability to fulfill the law’s true intent. Key Theological Pivot: Luke 18:26-27 “Those who heard this asked, ‘Then who can be saved?’ But He replied, ‘What is impossible with man is possible with God.’” The onlookers perceive correctly: If the socially blessed and outwardly moral cannot be saved by obedience, no one can. Jesus confirms their conclusion, relegating human effort to impossibility and locating salvation entirely in God’s initiative. Systematic Cross-References • Romans 3:20—“Therefore no one will be justified in His sight by works of the law.” • Ephesians 2:8-9—“For it is by grace you have been saved through faith…not by works, so that no one can boast.” • Titus 3:5—“He saved us, not by works of righteousness we had done, but according to His mercy.” Luke’s narrative anticipates and undergirds these later apostolic formulations. Patristic and Reformational Witness Augustine, Sermon 50: “He who made you without you will not justify you without you; therefore He bids you consent to Him who works, that you may escape the punishment of works done by yourself.” The father’s emphasis on consent, not contribution, mirrors Luke 18. During the Reformation, the pericope served as a prime text for sola fide defenses; it exemplified the bondage of the will by exposing even the best moralist as spiritually bankrupt apart from grace. Pastoral and Evangelistic Application 1. Expose idols gently: Like Christ, identify the unique barrier each person clings to for security. 2. Redirect to God’s character: Emphasize divine goodness and human deficiency. 3. Present the impossibility of self-salvation as the doorway to embracing the risen Christ, whose atoning death and victorious resurrection (1 Colossians 15:3-4) secure the “possible” for the impossible. Conclusion Luke 18:18 challenges salvation by works by (1) revealing the inadequacy of human goodness, (2) demonstrating that perfect law-keeping reaches beyond external compliance to heart allegiance, and (3) declaring that only God can accomplish the salvation humans cannot. The passage is therefore a narrative proclamation of grace, anticipating the full gospel of the crucified and risen Lord, and compelling every reader to abandon self-reliance and entrust eternal destiny to Christ alone. |
