Question: 1 Thess. 5:23: how do you explain sanctification here? M.
Answer: It is sanctification in practice, which all Christians admit and urge. The apostle prays that “the God of peace might sanctify them wholly”; and, not content with this general desire, “that their spirit and soul and body might be preserved entire, blamelessly, at the coming of our Lord Jesus Christ.” The whole man is comprehended, in virtue of the reconciling work on the cross; which awaits redemption in the full sense (Rom. 8:23) at Christ’s coming. It is the believing man inwardly and outwardly, the mind of flesh or old man already condemned, and all the rest, inner and outer, animated and directed by the indwelling Spirit of God. The higher faculty of man, his spirit, is named first, and the external instrument, his body, last; the soul, if we distinguish the words, is the seat of individuality, the “I” which uses both. It is a heathen notion, though favored by many moderns, to place the “I” in the spirit; but scripture is distinctly adverse, and the error involves many serious consequences. As to this, Dr. Delitzsch’s book is unreliable, though learned and lively.
