Never understanding

It is particularly late again. I have been listening to some Todd Agnew songs (haven't for ages) one based on Isaiah 6. I was doing something else online at the time but it's one of the few songs that really hits something home in me regarding God. It interuppted what I was doing - I'm not a super emotional person, but it definitely got there. The actual passage - "Isaiah's Commision" is actually quite disturbing. I love how it reveals some of who God is. It's quite beautiful in, "With it he touched my mouth and said, "See, this has touched your lips; your guilt is taken away and your sin atoned for." (v.7) But then this holy God goes on to tell Isaiah to let the people, "'Be ever hearing, but never understanding; be ever seeing, but never perceiving.'" I'm not sure I understand... This is really not the best of times to be thinking about theological stuff - and I'm not in a place where I can recall the story of Isaiah very well. But it is curious. There is a profound wonder and mystery about God. About his holiness and why God does what he does. At the same time I guess much of what this is about (or whether I'm being influenced by what I've gleaned through what I'm hearing) is about letting it all go and letting this Holy God be God. Who are we in light of God anyway. And more so, look at what he's done to place us in a position where we so clearly shouldn't be.
