If one of the direct descendants of the house of Aaron were converted to Christ, he would enter upon an entirely new character and ground of priestly service. And be it observed, that the passages just quoted present the two great classes of spiritual sacrifice which the spiritual priest is privileged to offer. There is the sacrifice of praise to God, and the sacrifice of benevolence to man. There is a double stream continually going forth from the believer who is living in the realization of his priestly place--a stream of grateful praise ascending to the throne of God, and a stream of active benevolence flowing forth to a needy world. The spiritual priest stands with one hand lifted up to God in the presentation of the incense of grateful praise, and the other opened wide to minister, in genuine beneficence, to every form of human need. Were these things more distinctly apprehended, what hallowed elevation and what moral grace would they not impart to the Christian character! Elevation, inasmuch as the heart would ever be lifted up to the infinite Source of all that is capable of elevating; moral grace, inasmuch as the heart would ever be kept open to all demands upon its sympathies. The two things are inseparable. Immediate occupation of heart with God must, of necessity, elevate and enlarge; but, on the other hand, if one walks at a distance from God, the heart will become groveling and contracted. Intimacy of communion with God--the habitual realization of our priestly dignity, is the only effectual remedy for the downward and selfish tendencies of the old nature. Having said thus much on the subject of priesthood in general, both as to its primary and secondary aspects, we shall proceed to examine the contents of the eighth and ninth chapters of the book of Leviticus.
