He didn't say I and God live in there. He said I and my Father are one. Only one person, only God. That made me cry sometimes before. That's when enlightenment begins to inch toward us, or we're crawling toward enlightenment, or maybe we're running, flying, it depends.
Some people fly, some people walk, some people go by, maybe train.
It's because sometimes we choose to go faster, sometimes we choose to go slower. We chose that before we were born. We were one and then we became many, as God wished it to be. We partake in the grand design of the creation to play in the colorful drama of life. And now, when the time comes that our role is finished, not necessary, or we're tired, then we want to retire, we want to go back Home.
