It is common in the Bible for people to "rise up," and it would be easy to pass over the phrase as simply describing a physical action. But in fact it represents an elevation in spiritual state, moving to a more internal frame of mind closer to the Lord. Often it has to do with understanding a new or important idea; we "rise up" to a state of greater perception and enlightenment. Obviously context is crucial to the exact meaning of the phrase in a given passage -- it matters greatly who it is that is rising up, and why.

126. LIGHT AND HEAT IN HEAVEN

People who think only from nature cannot comprehend that there is light in the heavens. Yet, such is the light in the heavens that it exceeds by many degrees the noonday light of the world. I have often seen that light even during the evening and night. At first, I marvelled when I heard angels saying that the light of the world is little more than a shadow in comparison with the light of heaven, but, having seen it, I can testify that it is so. The brightness and splendour are such as cannot be described. The things that I have seen in the heavens have been seen in that light, thus more clearly and distinctly than things in this world.
