Prophet
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.
Matthew 7:24-27
24
"Everyone therefore who hears these words of mine, and does them, I will liken him to a wise man, who built his house on a rock.
25
The rain came down, the floods came, and the winds blew, and beat on that house; and it didn't fall, for it was founded on the rock.
26
Everyone who hears these words of mine, and doesn't do them will be like a foolish man, who built his house on the sand.
27
The rain came down, the floods came, and the winds blew, and beat on that house; and it fell--and great was its fall."
