Looking at the world, I see that each person lives in a space of his own; and in most cases, that space is just a small cocoon. A person is shaped by his own experiences, how he was brought up, the society he lives in, and every thing or person he comes in contact with. He may continue to change; but basically, he shapes himself the way he likes ~ he is still himself inside his cocoon.
Once the person encounters God, then he's no longer confined to his limited space ~ he now enters the unlimited space outside to live, letting God shape him into a new creature, free and beautiful.
A simplified description, but true.
