I believe the God is a person. He looks like us (we are his children), but He is perfect. Nobody and nothing is better or more powerful. Since He is perfect, He never lies and never makes mistakes. This is why I enjoy reading his teachings, promises and prophecies in the Bible.
His whole concern is the spiritual welfare of his children. If we keep his commandments and behave according to the consciousness He has given us, we grow spiritually. In other words, we become more like him, more perfect and more happy.
So, I don't think God is concerned with the power thing. He is not trying to impress us with his might. Therefore, I don't think He would ever waste his time to create the heaviest rocks or attempt to break any other records, etc. He loves us and if we accept his invitation to follow his directions, he will give us all He has (including his character and the joy He experiences).
