For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
'For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.' Jesus continues quoting Isaiah 6:10, explaining why seeing/hearing don't produce understanding: the 'heart is waxed gross' (ἐπαχύνθη γὰρ ἡ καρδία/epachynthē gar hē kardia)—literally 'has become fat, thick, insensitive.' Their ears are 'dull' (βαρέως ἤκουσαν/bareōs ēkousan, heavy, sluggish); their eyes 'they have closed' (ἐκάμμυσαν/ekammysan)—active voice indicating deliberate choice. This grammatical detail is crucial: they closed their own eyes. The result: they won't see, hear, understand, be converted, or be healed. Reformed theology sees both human responsibility (they closed their eyes) and divine judgment (God confirms their hardness). The verse describes willful blindness becoming judicial blindness: persistent rejection leads to inability to respond. The tragedy: they avoid conversion and healing—missing salvation through stubborn resistance.
Historical Context
Isaiah's original context: eighth-century BC Judah under Ahaz and Hezekiah, facing Assyrian threat while trusting Egypt rather than God, maintaining temple worship while oppressing poor, performing sacrifices while violating covenant. Their hearts had 'grown fat'—self-satisfied, comfortable in sin, resistant to correction. The metaphor: overfed animals become sluggish, insensitive. Similarly, Judah's spiritual obesity (prosperity, self-righteousness, religious routine) deadened spiritual perception. By Jesus's time, pattern repeated: religious establishment was self-satisfied, comfortable, resistant to prophetic challenge. They had everything—Scripture, temple, tradition—yet missed Messiah standing before them. They'd closed their eyes deliberately, refusing evidence that threatened comfortable assumptions. Church history shows this pattern continuing: Christendom's prosperity often produces spiritual obesity—comfortable religion losing vital connection to truth. Reformation was partly reaction against this. Modern Western church faces similar danger: material comfort, cultural Christianity, self-satisfied moralism blinding eyes to genuine gospel. Fat hearts can't perceive truth requiring repentance and transformation.
