As The Morning Light

Then shall thy light break forth as the morning, and thine health shall spring forth speedily: and thy righteousness shall go before thee; the glory of the Lord shall be thy rearward. (Isaiah 58:8)

And if thou draw out thy soul to the hungry, and satisfy the afflicted soul; then shall thy light rise in obscurity, and thy darkness be as the noonday: And the Lord shall guide thee continually, and satisfy thy soul in drought, and make fat thy bones: and thou shalt be like a watered garden, and like a spring of water, whose waters fail not. (Isaiah 58:10-11)

And thine age shall be clearer than the noonday; thou shalt shine forth, thou shalt be as the morning. (Job 11:17 - Zophar the Naamathite)

The quote from the book of Job may be useful to establish the idea that shining like the morning is a good thing, if we had not already. The person speaking there is one of Job's friends, I believe Job's friends were fundamentally wrong in their description of God and his ways (Job 42:7) so I don't trust anything they say. Therefore any point that rests on a quote from Job's friends is null or worse as far as I am concerned. But we don't need Zophar to imply for us that light is good; it is just worth knowing that this same language is used elsewhere as a description of great peace and security (look at context of Job 11).

So what is all this talk about light and the morning in Isaiah 58 about? I am inclined to think it makes sense as a direct word picture without need for cross referencing, though if you can think of any good references I'd be glad to see them.
Currently I see it in terms of a man who wakes up to do something outside (work or travel) before dawn, which would have been common enough in those days. It's a pity we don't rise before dawn these days, that's something I would like to do more often. The man is walking outside and it is dark enough that he stumbles a little bit. There is light, so he can see most obstacles, big things like trees and rocks. But he blunders against small branches and stones and steps on animal droppings. But gradually without him noticing, the light gets brighter. He would never be able to tell you when it happened, but suddenly it is broad daylight and he realises he has already stopped stumbling because he could see better than he realised. He is walking in the light but thinks he is walking in darkness. The man who walks and sunset has the opposite experience, the light is fading but he thinks he is walking in the light until he stumbles and falls.
The experience of having light rising like the morning is the experience of those at the end of time who will cease to stumble but not realise it until the broad daylight of Jesus' second advent comes. Do the good works that Jesus has given you and repent of your sins that your light may come as the morning.
