sick & healthy

Had a teeny revelation in the Jeep on my drive home from school. A sick person does would not know he is sick unless he has been healthy, or seen someone else who is healthy. In the same way, there would be no right or wrong--no morality, no set of universal moral laws--unless there was a greater morality, a morality-maker (God). And someone wouldn't know the full extent of how sinful or terrible he or she is until they see God face-to-face, until they dwell in God's presence.

I'm no theologian, so if I've made any mistakes in my ideas (in your opinion), please let me know.
