John 9:40: Rethink sin and guilt?
How does John 9:40 challenge our understanding of sin and guilt?

Text

“Some of the Pharisees who were with Him heard this, and they asked Him, ‘Are we blind too?’” (John 9:40)


Immediate Setting

Jesus has just healed a man born blind (John 9:1–7). After a lengthy interrogation by the Pharisees, He declares, “For judgment I have come into this world, so that the blind may see and those who see may become blind” (v. 39). Verse 40 records the Pharisees’ indignant response—an incredulous question that lays bare their self-perceived moral clarity.


Narrative Irony and Rhetorical Force

John’s Gospel often uses irony: those who boast of sight are exposed as blind, while an uneducated beggar becomes the exemplar of true vision (cf. 1 Corinthians 1:27–29). The Pharisees’ question, “Are we blind too?” drips with sarcasm, yet unintentionally invites Jesus’ devastating verdict in v. 41: conscious rejection, not ignorance, cements guilt.


Spiritual Blindness versus Physical Blindness

Scripture repeatedly pairs physical impairment with spiritual reality (Isaiah 6:9–10; Matthew 13:13–15). The healed man illustrates that physical blindness, when met by divine grace, leads to worship (John 9:38). In contrast, the Pharisees’ willful blindness springs from hardened hearts (John 12:37–41, citing Isaiah 53 and 6). John 9:40 thus reframes sin: it is less a defect of intellect than a refusal to receive light (John 3:19–21).


Knowledge and Moral Accountability

Jesus’ rejoinder in v. 41—“If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains”—articulates a biblical maxim: revelation increases responsibility (Luke 12:47–48; James 4:17). Guilt is not merely the presence of wrongdoing but the conscious spurning of known truth (Romans 1:18–23). John 9:40 exposes how self-assured religiosity heightens culpability.


Old Testament Foundations

The Torah links unintentional sin with lesser guilt and intentional sin with “high-handed” rebellion (Numbers 15:22–31). Prophets decry leaders who are “watchmen … blind” (Isaiah 56:10). John positions the Pharisees within this prophetic critique, intensifying the gravity of their question.


Second-Temple Background

Qumran texts (e.g., 1QS 3.19–25) contrast “sons of light” with “sons of darkness,” mirroring John’s light–darkness motif. Contemporary Jewish writings expected Messiah to heal the blind (cf. 4Q521). Jesus’ miracle fulfills that hope, leaving the Pharisees without excuse.


New Testament Parallels

Matthew 15:14—blind guides of the blind

Romans 2:17–24—the self-styled instructor blind to hypocrisy

2 Corinthians 4:3–6—the god of this age blinds unbelievers

These passages echo John 9:40, underlining that presumption of sight can harden blindness.


Systematic Theology: Hamartiology and Soteriology

1. Hamartiology: Sin includes willful resistance to divine revelation (Hebrews 3:7–12).

2. Soteriology: Only Christ grants true sight (John 1:4–5, 9). Acknowledging blindness is prerequisite to receiving grace (Revelation 3:17–18).


Practical Application

1. Self-Examination: Ask God to expose hidden pride (Psalm 139:23–24).

2. Evangelism: Emphasize need to confess blindness; the gospel is light, not condemnation (John 3:17).

3. Discipleship: Cultivate humble teachability; spiritual growth depends on continual openness to light.


Conclusion

John 9:40 challenges any complacent view of sin and guilt by showing that the gravest danger is confident self-righteousness. Those who claim sight yet reject Christ remain under guilt; those who admit blindness find healing and illumination in Him.
