Every now and then I think about how grateful I am to not be blind - mostly because I'm scared. What if there was a huge spider next to me and I couldn't see it? What if there was something gross in my food and I didn't know about it? Our eyes are what interpret the light which is all around us - imagine living in darkness!
After telling us he is the bread of life, Jesus now tells us he's the light of life. Jesus is 'so rich and glorious that not a single name can describe him, and not a single metaphor can do justice to his greatness.'
