I just really hate this, and I want to post it somewhere so I can say I hate it. I've never understood the "fill my heart with you, Lord" kind of thing... So much of that evangelical language sounds like either romantic or sexual love to me, and in the context of a relationship with God that just weirds the crap out of me. But this "empty me of me" business? What the hell?
Why would you want to be emptied of yourself? Why would God want that for you? If God didn't want you to be you, then what is the entire point of your life? I ask you.
