Hearing but not listening to God's word.
Anyone that makes and trusts in those idols will be likened unto them, having ears but do not hear, having eyes but cannot see. These are people, even if they hear the word of God,but to listen to it. The real meaning of to listen because the bible gives us the meaning but surely they can hear the word of God. But really, as you asked, people do not listen to it. Why? Psalm chapter 115 verse 4 says, their idols are silver and gold, the work of men's hands.
Verse 5 says, they have mouths, but they speak not:eye have they,buy they see not.
Verse 6 says, they have ears, but there hear not; noses have they, but they smell not.
Verse 7 says,they have hands, but they handle not, feet have they, but they walk not: neither speak they through their throat.
Verse 8 says, they that make them are like unto them; so is everyone that trusteth in them.
Men in out generation have been like their idols,their God's. "Their idols" according to the word of God. So, is everyone that trusteth in them. Our generation is a generation of idol worshippers,religion that worship idols. Act 17 verse 29 says, For as much then as we are the offspring of God,we ought not to think that the Godhand is like unto gold, or silver, or stone, graven by art and man's device.
We ought not to think, to even think that there is divinity in those things.
The word, "Godhead" is translated in other translations as "divinity".the light will not shine of God will not shine upon this people(the idol worshippers ) because the God to his world, which is Satan.those who do not believe in the true God of the bible, will automatically be blinded by Satan,the enemy of God that why you cannot expect them to hear and obey.
