Your Father Who Sees in Secret

But you, when you pray, go into your inner room, close your door and pray to your Father who is in secret, and your Father who sees what is done in secret will reward you. (Matt 6:6)

There is a sense in Christianity that thoughts matter and "improper" thoughts (e.g., coveting and lust) are sinful and morally wrong. Now, my understanding of Buddhism (and I make no claim to be an authority on the subject) is that thoughts are random and unavoidable and it is best not to get caught up in them. So, under one system these thoughts are crimes requiring a system of justice to mete out punishment and under the other, the thoughts themselves are in a sense their own punishment. Is there some way to reconcile these two positions?

I've often thought that the external, personal deity of Christianity is a metaphor for the actual thing. On one level this makes sense because God being outside of creation is probably not bound by the rules of creation and any attempt to define Him would probably define Him as an entity less than He actually is. This reminds me of a statement my freshman year roommate made to justify his non belief in an omnipotent god. "Can God make a rock so heavy that he can't lift it?" This question, I think, points out the limited nature of speech to describe the divine more than it offers an insight into the divine. So, what we cannot define with words, we describe with symbols.

The question then becomes, who is this Father that sees in secret? Is it an external entity sitting on a throne? Is it a deeper part of the self? Is it something else entirely? I think the answer to this question might serve to reconcile the Christian and Buddhist concepts of thought. But I really can't be any more specific than that. It's a cop out, I know.
