What does The Bible say about Baptism?

Inspired by our series on "The Lies and Hypocrisy of Chrisitanity," we are embarking on another themed series, though we will continue our orignial series. "What does The Bible say about..." is similar to our series on Christianity except rather than address the denominations, we will discuss what The Bible really says about various topics.

(in the Christian Church) the religious rite of sprinkling water onto a person's forehead or of immersion in water, symbolizing purification or regeneration and admission to the Christian Church. In many denominations, baptism is performed on young children and is accompanied by name-giving.

Baptism is also defined as a trying or purifying experience or initiation.
