The "Messiah" will not be in the shape of a single person, so the reference to whether or not it's the "first" or "second" coming of the Messiah is irrelevant. The "Messianic Age" or "Age of Christ Consciousness" or "New Energy" may be more accurate terms. The Age will not be ushered into existence by a single person. Rather, it will be the age when humanity as a whole manifests the Christ Consciousness, when this Consciousness that is innately within each human BEing becomes the guiding energy behind the thoughts, actions, and feelings of each human on the planet. God is made manifest in the Temple, or the flesh, of every human BEing; God is incarnate in every human BEing. When humanity as a whole remembers who We are, that We, too, are God, then the Age of Christ Consciousness will be ushered in.
