Ears to hear

I'm reminded (too frequently, it seems) that not everyone who listens to the teaching of God's Word (at least my teaching) gets it.  Either by words or actions, I'm often baffled by behavior or sentiment that is clearly contradicted in Scripture.

Jesus uttered these words on several occasions as He taught His disciples. "He who has ears to hear, let him hear", implying that hearing alone doesn't translate into comprehension.  I expect that from new disciples.  But I'm ever frustrated by mature believers who miss it.

Then again, I'm sure the Lord has some similar frustrations with me.

"Open our ears, Lord, and help us to listen."
