Just as Eve was flesh and bone of Adam. There is a parallel between the first Adam and the last Adam. The first Adam had a rib taken out of him to make a woman. The last Adam had the same done to him. Blood is for cleansing and life.
Water is for destruction and burial.
Let's take a quick look at something else. Christ has a literal body of flesh and bones. Therefore, our body will become like his body in the resurrection. Note that each time that wife or bride is mention it is always in reference with or to Christ or Lamb. Therefore, let the bride look for the marriage ceremony.
