"So then, when the end has been restored to the beginning, and the termination of things compared with their commencement, that condition of things will be re-established in which rational nature was placed, when it had no need to eat of the tree of the knowledge of good and evil; so that when all feeling of wickedness has been removed, and the individual has been purified and cleansed, He who alone is the one good God becomes to him 'all,' and that not in the case of a few individuals, or of a considerable number, but He Himself is 'all in all.' And when death shall no longer anywhere exist, nor the sting of death, nor any evil at all, then verily God will be 'all in all."
