Immersion in the water is about purification, about liberation from the filth of the past that burdens and distorts life—it is about beginning again, and that means it is about death and resurrection, about starting life over again anew. So we could say that it is about rebirth. All of this will have to wait for Christian baptismal theology to be worked out explicitly, but the act of descending into the Jordan and coming up again out of the waters already implicitly contains this later development.
