(1) That which regards it as referring to the Holy Spirit, the third person of the Trinity. This was the opinion of Owen, Doddridge, and archbishop Tillotson.
(2) That which refers it to the “divine nature” of Christ. Among those who have maintained this opinion, are Beza, Ernesti, Wolf, Vitringa, Storr, and the late Dr. John P. Wilson. mss. Notes.
(3) Others, as Grotius, Rosenmuller, Koppe, understand it as meaning “endless” or “immortal life,” in contradistinction from the Jewish sacrifices which were of a perishable nature, and which needed so often to be repeated.
(4) Others regard it as referring to the glorified person of the Saviour, meaning that in his exalted, or spiritual station in heaven, he presents the efficacy of his blood.
(5) Others suppose that it means “divine influence,” and that the idea is, that Christ was actuated and filled with a divine influence when he offered up himself as a sacrifice; an influence which was not of a temporal and fleeting nature, but which was eternal in its efficacy. This is the interpretation preferred by Prof. Stuart.
