Yeah, that's right. But immersing people in water is also an important part of our calling as ministers. Baptism reminds us that our souls, like our bodies, need cleansing. If we cannot live in this world without getting our hands dirty, neither can we go about our daily business without our souls needing a good scrubbing too.
Washing is one good metaphor for what baptism means.
Before baptism, what dies within you when you commit your life to Christ is a great attraction to sin, to self-destructive acts. What is born within you when you commit your life to Christ is a great attraction to God. It is as though a switch is thrown deep within you, and you turn from all that makes you less of a person, and you turn towards God, the one who makes us truly ourselves and truly free. We create a soul out of our choices and our loves, both those that make us more of a person, and those that make us less. Our souls are built out of what we promise and what we love.
