"Man doth not live by bread only, but by every word that proceedeth out of the mouth of Jehovah doth man live." -Deut. viii. 3.
THUS is it asserted that the WORD and the WORDS of Jehovah constitute the food of the new nature.
As in the natural sphere so in the spiritual, the desire (or appetite) for the food which is the proper support of each respectively, is the sign of natural and spiritual health.
