How does Mark 10:18 challenge the concept of human goodness? Canonical Text “‘Why do you call Me good?’ Jesus replied. ‘No one is good except God alone.’” – Mark 10:18 Immediate Narrative Setting Mark 10:17–22 recounts a wealthy young ruler kneeling before Jesus and asking, “Good Teacher, what must I do to inherit eternal life?” (v. 17). Jesus first corrects the ruler’s understanding of goodness before exposing his idolatry of wealth. The exchange sets goodness, eternal life, and discipleship in direct relationship to the character of God. Jewish and Greco-Roman Concepts of Goodness Second-Temple Judaism reserved “Good” (טוֹב, tov) as an attribute of Yahweh (Psalm 34:8; 100:5). In the Hellenistic milieu, philosophers like Plato spoke of “the Good” as the highest form; yet in practice “good man” was a relative compliment. Jesus bypasses cultural gradations to anchor goodness exclusively in the divine nature. Systematic Theology: God Alone Good Divine goodness is communicable only by grace, never intrinsic to fallen humanity. God’s goodness is: • Immutable (James 1:17) • Intrinsic (Exodus 33:19) • Expressed supremely in Christ’s atoning death and resurrection (Romans 5:8) Anthropology: Human Fallenness Scripture consistently indicts humanity: • “There is no one righteous, not even one” (Romans 3:10). • “All have sinned and fall short of the glory of God” (Romans 3:23). • The heart is “deceitful above all things” (Jeremiah 17:9). Mark 10:18 therefore confronts any self-assessment of inherent virtue. Behavioral research likewise confirms pervasive moral biases, aligning empirical observation with biblical anthropology. Christological Claim Embedded in the Question Jesus does not deny His deity; He forces recognition. If only God is good and Jesus is good, the ruler must conclude Jesus is God incarnate (cf. John 10:30). The text thus simultaneously challenges human goodness and affirms Christ’s divine identity. Biblical Cross-References • Psalm 14:3; 53:3 – universal corruption. • Isaiah 64:6 – righteousness as “filthy rags.” • Ephesians 2:8–9 – salvation by grace. • Titus 3:5 – “not by works of righteousness.” • 1 John 1:8 – self-deception regarding sin. Historical Reception • Early Fathers (e.g., Irenaeus, Adv. Haer. IV.12.5) cited the verse to underscore Christ’s divinity. • Augustine leveraged the passage against Pelagian claims of innate human goodness. • Reformers employed it to defend sola gratia. Ethical and Behavioral Psychology Perspective Empirical studies on moral self-licensing, altruistic punishment, and implicit bias reveal that perceived goodness often masks self-interest. These findings corroborate Mark 10:18’s diagnosis that true, unalloyed goodness is absent apart from God. Practical Application for Believers and Evangelism 1. Begin gospel conversations by defining goodness via God’s standard, not cultural comparison. 2. Use the commandment inventory (vv. 19–20) to reveal hidden idols. 3. Point to Christ’s resurrection as historical proof that the only truly Good One conquered death, validating His authority to grant eternal life. Objections Considered • “Jesus denies His deity.” Answer: He invites recognition by linking Himself with the divine attribute exclusively. • “Humans perform altruistic acts.” Answer: Relative goodness exists, but Jesus speaks of absolute moral perfection. • “The verse is hyperbole.” Answer: The context shows a deliberate theological assertion, not exaggeration. Summary Mark 10:18 dismantles the notion of inherent human goodness, redirects moral evaluation to God’s perfect character, and implicitly reveals Jesus as the incarnate Good One. It thus prepares the heart to abandon self-reliance, embrace grace, and glorify God through faith in the risen Christ. |
