Water ... has an enormous range of meanings for us as human beings. Our bodies are mostly water, and our thirst reminds us to replenish that water. We are born from the waters of the womb, and something about a pool draws us to plunge back into it and covers ourselves. But if we stay under for too long, it means death. Coming up to the surface and breathing again is almost like being reborn. ... Water washes us clean and makes us feel fresh and new again. Baptism takes - and adds to - all these meanings.
