The idea of a "prophet" is very closely tied to the idea of the Bible itself, since the Bible was largely written by prophets. At a lower level, prophets represent people who teach from the Bible. At a higher level, they represent the Lord as He reveals himself through the Bible. Viewed in a abstract way, prophets represent the holy parts of the Bible themselves, and also represent doctrine drawn from the Bible. The reason we say "largely written by prophets" and "the holy parts of the Bible" is that not all of the books currently included in the Bible have a complete and continuous internal sense. Some -- like Job, Ruth, and Song of Solomon -- are wonderful literary pieces that got included, but which lack the systematic meanings for words and phrases. Others -- the Acts and Epistles, primarily -- are really doctrinal works, the first attempt by others to extract meaning from Jesus' life and words.

The nature of the soul is a deep and complicated topic, but it can be summarized as our spiritual life — that is, who we are in terms of our thoughts and affections. And that, generally, is the internal sense when the Bible talks of a soul. You could be missing limbs, disfigured in the body due to illness or accident, paralyzed, but you would still be a complete human being. That's because the soul is the real you, and the soul has to do with internal things, not the state of your body.
