I have often wondered what the trinity represents. I can't recall where it is written in the bible -- maybe because it is just not a critical issue, and so has never meant much to me personally. But I posted this here because it was a fairly recent dream.
Dreams can sometimes lie and sometimes tell the truth, depending upon how we are doing in attempting to be truly religious: untainted by the world (NT).
So trinity is not critical. But I will tell you the interpretation of the dream: the teacher is conception, the son is execution and the holy ghost is manifestation.
So the dream is suggesting the trinity is about three parts of prayer pertinent to making anything happen. Or three parts of one's understanding of God.
