Man is defined by Mary Baker Eddy in the Glossary of "Science and Health with Key to the Scriptures" as, "The compound idea of infinite Spirit; the spiritual image and likeness of God; the full representation of Mind" (p. 591). In referring to Christ, the true idea of sonship, Paul wrote (Col. 2:9), "In him dwelleth all the fulness of the Godhead bodily." That which is full is complete, entire, perfect, having abundance. Depletion cannot, therefore, be a true state of being; rather is it a spiritual impossibility.
Truth is true for all time; therefore the realization that individual man forever includes in his God-created being every good and right idea obviates the possibility of depletion or lack of any sort ever entering our experience. This does not mean that man individually reflects the whole of God, but that in a degree the completeness of the divine nature is reflected by each individual idea.
Good can never be subtracted from being; rather is it, in its every aspect, constant in manifestation, as this passage from Ecclesiastes indicates (3: 14): "Whatsoever God doeth, it shall be for ever: nothing can be put to it, nor any thing taken from it." In view of this Scriptural assurance, completeness must be recognized as the normal and abiding condition of the child of God, who can never manifest or experience anything underived from the divine Mind, Spirit, the real source of being.
