I am reminded again that God chose to be like one of us. His true form--even His existence--is beyond our comprehension, so He became like us to make it easier for us to understand Him. Even then, we still find ourselves lacking in understanding of who He is and what He means.
For that matter, we do not understand ourselves. We are more than the flesh that we inhabit. Certainly, our own transfigurations will help us better understand who we are as well.
