Nor, in the strict sense of the terms, can any thing but the DIVINE LIFE, or the life of God in the soul, be called life. Those who have gone astray from God, just so far as they have lost the divine life, and have sunk into the natural life, are dead. Hence, the expressions of the apostle: — "And you hath he quickened, who were dead in trespasses and sins." Ephes. 2:1. The eternal vitality, the breath from the Infinite, the life of God in the soul, ceases to be in them. And being dead, by the absence of God as an indwelling principle, they must be recreated, or born again, by his restoration. It is not enough, that provision has been made, in the death of Christ, for man's forgiveness. Forgiveness, it is true, has its appropriate work. It cancels the iniquity of the past; but this is not all that is necessary. It is not without reason, that the learned Schlegel commences his profound work on the philosophy of history by saying, that "the most important subject, and the first problem of philosophy, is the restoration in man of the lost image of God." The immortal nature must be made anew, must be re-constituted, if we may so express it, on the principle of life linked with life, of the created sustained in the uncreated, in the bonds of divine union.
