Seems every church and person has their own distinct notions of baptism. The Catholics perform child sprinklings, the Baptist adult immersion, the Mormons for even the dead. Some deny it is even important at all. What are your beliefs concerning baptism and why?
I believe that Baptism is a sacrament in the most literal sense of the word- an outward sign of an inward grace. Baptism is not just in physical water, but also in spirit. The physical water is just an outward sign that gives our limited minds a focus point of the mystery.
A person can be baptized and totally miss the significance of it. This is okay, God's grace in the act is not reliant on our failings or inability to understand, and one need not be baptized more then once.
Baptism to me is when we wake up, become aware of Christ within us, and we within Christ. This is called being baptized unto Christ, and putting on the mind of Christ. One does not need to be physically baptized in water to do this, but the sacrament is show of faith and obedience to the teachings of Jesus.
It is because Baptism is symbolic of enlightenment (by knowledge/gnosis) that I think education on the true significance of Baptism is important. You don't want to get baptized without understanding the spiritual mystery of the sacrament.
I believe that Baptism should be pursued by all Christians in obedience, and that if a person dies unbaptized, but had the intention of being baptized, they are baptized by the desire.
