The Four Elements

For Jesus to be born at the Winter Solstice, he would have been crucified (crossed) from spirit (Air) into water at the Vernal Equinox. Water is, in fact, the result of the union of Air (Spirit) and Hydrogen (Matter), as water is literally two parts Hydrogen to every one part Air. 

The transit of the Soul is as follows: first Spirit (Air: the Word of God) is breathed into being. Before it can manifest into matter, it first passes through water (the womb - the conception), and then into flesh (the tomb - berth from water to flesh). The terms berth and birth are not only phonetically the same, but likewise, both signify the same exact event: a ship berths at a port, just as a child is birthed from the watery womb. That is the transition of Spirit (Air) into Flesh (Matter) through Water.

Likewise, once man is conceived, he is first nourished by liquid within the womb, then by solids (matter) after berth.

If man so chooses, he is next nourished by the Spirit (Air - the Word of God), which "dries" him, ultimately leading to his ascension back into spirit through Fire. Those who choose not his Word, are burned off in the Lake of Fire, just as Fire burns off all impurities.
