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.

9. A man who has thoroughly confirmed himself in the faith and doctrine of the present-day Church, may make no account of repentance, of the law of the Decalogue, nor of works and charity. For he can say, "I cannot do good from myself; these things are included in faith, whence they proceed one by one without my knowing it;" and so forth. This, also, is the source of the naturalism which prevails at the present time.
