Soul - Quickening

There is however another spirit which may be termed the divine . . . Souls deprived of that spirit are accounted as dead, though they are possessed of the human spirit . . . By this He means that souls though alive in the human kingdom are nevertheless dead if devoid of this particular spirit of divine quickening. They have not partaken of the divine life of the higher kingdom; for the soul which partakes of the power of the divine spirit is verily living.
