The Spirit of God…acts in the mind of a saint as an indwelling vital principle. He acts upon the mind of an unregenerate person as an extrinsic occasional agent; for in acting upon them he doth not unite himself to them; for notwithstanding all his influences that they may be the subjects of, they are still “sensual, having not the Spirit” (Jude 19). But he unites himself with the mind of a saint, takes him for his temple, actuates and influences him as a new, supernatural principle of life and action. - WJE 17:411
