conversations with God

I have been learning a lot about changing the person you are being in order to experience different results, and as I lay on my bed this morning two very distinct thoughts were given to me about the true nature of things. At some point we have to realize that this page, computer, house or where ever you are is temporal. That is widely accepted and recognized in Christendom. But what about...

Thought 1: Who you are is a lie; it changes.
Thought 2: The truth is that you are.

The point being that you will wear many hats during this lifetime and you will be thought of in many different ways. None are true because they are passing. But, the fact that you are remains. You will be for all eternity. Does that change the way you play your cards?
