From the depths of his boundless affection for all, Jesus prayed, "That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us." It was in this oneness of being that he saw the greatest good, and it is this oneness of being, this entirety of good, that Christian Science is unfolding universally today.
The oneness of being is the essence of the brotherhood of man. It would be impossible for an individual to be at one with the Father and at the same time to accept the suggestion that there was someone who was not, for to admit anything but good, whether for oneself or another, would mean separation from the consciousness of all good. One could not be completely happy himself and at the same time know that someone else was unhappy. One could not be completely aware of the abundance of Love and at the same time believe that lack was present for someone else.
In the oneness of being, all is perfect, and the perception of this shatters the falsity that there could be lack or limitation, ignorance or sin, unhappiness or frustration, for anyone anywhere. In order to experience the oneness of being in its depth and fullness, it is essential to think universally, to reject everything unlike good, and to acknowledge divine selfhood as the only reality, so finding the universality of good, the brotherhood of man, increasingly evident. Paul's words to the Corinthians, 'Come out from among them, and be ye separate," therefore, would mean to separate oneself from—to eliminate—every material belief and thereby bless all mankind.
