In a previous post, I mentioned Puritan Poet John Milton's sonnet that he wrote to the glory of God on the occasion of his going blind. For those who may be interested, here's a nice slide presentation put together by Andre Oosthuysen, a teacher. The poem, itself, is on slide #2, with the story behind it on the very next slide. Enjoy.
