In order to commemorate the deliverance which God wrought for Israel when he slew the first-born of Egypt, for a sign he claimed, as consecrated to himself, all the first-born of their males, "Thou shalt set apart unto the Lord all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be the Lord's." "And it shall be for a token upon thine hands, and for frontlets between thine eyes: for by strength of hand the Lord brought us forth out of Egypt."[710] The first-born of their sons represented the whole nation as a holy priesthood. Princes and heads of families, whether fathers or eldest sons—succeeding to their fathers' privileges—had performed the duties of priests. Such a character, therefore, the first-born in Israel would have come to sustain. When religious services should have been performed by them, the whole people, as a nation of priests, would have worshipped. And of whatever they were the token, the people at large, accordingly, were also the sign. But instead of them, subsequently the tribe of Levi was taken, and the special duties of the priesthood were confined to Aaron and his sons. Hence that appointed priesthood, and the Levites their attendants, conducted public services instead of, and for the whole nation, a kingdom of priests. And as the first-born of Israel were a sign of a great deliverance wrought for them because of his covenant, the people themselves, the ordained priesthood among them were, and all the people of God will continue to be, a Covenant sign.
And according to their character is this holy priesthood as a sign employed. Different from the other signs, their language with theirs is designed to harmonize. As willing ministers of God's pleasure, to other signs they give regard, proving themselves a living sign. When the rainbow displays its spiritual glories, by others unperceived, like Noah standing by the altar of God, they present sacrifices of thanksgiving, or vow and swear to him. When the Sabbath points out a rest from sin, and deliverance from its consequences, they seek to sanctify it, and keep it as a sign and pledge of the rest provided for them in the covenant. And having in baptism had the name of God named upon them, endeavouring to depart from all iniquity, they manifest themselves as by purchase and conquest, and their own personal surrender, truly his.
In some respects are all the ordinances of religion a Covenant sign, and it is as set apart to wait on these that the holy priesthood displays a like character. To them in all their extent are applicable the words of the Lord concerning Phinehas,—"Behold, I give unto him my covenant of peace."[711] As lights in the world, and as a devoted people, they have verified to themselves the promise,—"They shall teach Jacob thy judgments and Israel thy law; they shall put incense before thee, and whole burnt-sacrifice upon thine altar;" being faithful in discharging their solemn obligations, and thus illustrating the duty of paying the vow, their conduct, in vowing and fulfilling their engagements, receives the approval—"they have observed thy word and kept thy covenant;" encouragement from above is vouchsafed to them in their peculiar character, in the words of prayer,—"Bless Lord, his substance, and accept the work of his hands;" and thus, the assurance that as a sign they shall be preserved,—"smite through the loins of them that rise up against him, and of them that hate him, that they rise not again."[712]
God's covenant with his people is the covenant of a priesthood. And to secure the dispensation of the means of grace, that was given. The ministry of reconciliation and the Church at large are co-ordinate. Where the one is promised, the other also will be bestowed in due time. Where the ministers of the word are, there, to a greater or less extent, will be a Church. And a Church will seek to itself the ministering servants of Christ. Where the ordinances of religion are properly dispensed, there is a Church; and there an appointed instrumentality, in greater or less measure, presents the mind of Christ. When his servants dispense the ordinances of his grace, God speaks to his people. And as a people in covenant with Him, to his words they are called to assent. His servants are ambassadors for Christ. As though God did beseech by them, they beseech sinners to be reconciled unto him. Like the Church itself in the world, the continuance of the ambassadors of Christ shows that God is waiting to be gracious. They who despise their messages declare themselves his enemies. Like the recal of an envoy, which betokens approaching hostilities, the removal of the servants of Christ from among a people, declares that the Lord is about to deal with them as his foes. When Churches become corrupt, this is the case. When the righteous are removed from among them, and the ecclesiastical constitution is in opposition to his will, the whole body is out of Covenant, and what was the temple of God becomes the receptacle of idols. When the Lord was angry with his professed people, he suffered a lying spirit to enter the mouth of their prophets. And to the people as a whole, in token of their rejection, he said, "Thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children."[713] But notwithstanding the defections of many such, the Lord will raise him up a faithful priesthood. It is expressed in the anticipation, "The children of thy servants shall continue, and their seed shall be established before thee;"[714] and pledged in the promise, "Lo, I am with you alway, even unto the end of the world." Hence the encouragement, "I will give you pastors according to mine heart, which shall feed you with knowledge and understanding;"[715] and the duties defined, "The priest's lips should keep knowledge, and they should seek the law at his mouth: for he is the messenger of the Lord of hosts."[716]
Those faithful to the covenant of the priesthood are approved, while the desecrators thereof are fearfully condemned. How encouraging the approbation, "Ye shall know that I have sent this commandment unto you, that my covenant might be with Levi, saith the Lord of hosts. My covenant was with him of life and peace; and I gave them to him for the fear wherewith he feared me, and was afraid before my name. The law of truth was in his mouth, and iniquity was not found in his lips: he walked with me in peace and equity, and did turn many away from iniquity!" And how cheering the promise, in its ultimate spiritual reference not less applicable to the whole spiritual priesthood than it was primarily to the sons of Aaron!—"But the priests the Levites, the sons of Zadok, that kept the charge of my sanctuary when the children of Israel went astray from me, they shall come near to me to minister unto me."[717] But denounced are the others thus challenged, "Ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith the Lord of hosts." An apostate priesthood taught the people to swear at once by the Lord, and by Malcham—the abomination of the Sidonians—a false god. To cut off these, and the victims of their deceit, the Lord stretched out his hand. And to mark the care with which he watched over the faithful dispensation of his own ordinances, and observed every deviation from them, as designed to present the privileges and duties of his covenant, were also uttered his words, "Cursed be the deceiver, which hath in his flock a male, and voweth and sacrificeth to the Lord a corrupt thing: for I am a great King, saith the Lord of hosts, and my name is dreadful among the heathen."[718]
A priesthood was recognised when God entered into covenant with Noah, and with Abraham; and throughout all time was a priesthood to be approved as a covenant sign. Had it not been for the Everlasting Covenant, the rite of sacrifice had not been instituted, and a priesthood had not been. But that the ratification of that covenant by the glorious Surety might first be prefigured, and next had in commemoration, was given this sign. To intimate the ratification of God's covenant with his people, as at Horeb, the blood of sacrifice by the priesthood was sometimes sprinkled; and, consequently, the priesthood, under the law, kept up the remembrance of the covenant, and pointed forward to its final confirmation. The later priesthood, the people of God under the gospel, in offerings of praise, record that one sacrifice by which it was rendered sure, and hence they, as well as all else of the holy priesthood, to its special duties of vowing and swearing, from their peculiar character, became engaged.
Although of those who ministered at the altar under a former dispensation, it is said by an apostle, "those priests were made without the swearing of an oath,"[719] we are not to suppose them as not indeed by covenant set apart to the duties of the Levitical priesthood; nor are we to suppose that the people of God, as a holy priesthood in general, whom those priests represented, do not sustain their character in virtue of Covenant arrangements. Those priests, on believing, were entitled to the blessings promised and secured by the oath of God to Abraham's seed. And so were the rest of his Covenant people. Moreover, the Lord sware to his people at Horeb, when, in addition to the moral law, he enjoined all those other laws, among which stand the statutes regarding the priesthood of Aaron. To his people then present, whether priests or not, and to his people who should descend from them, throughout the period over which the covenant there made should extend, his oath was given; and seeing it was then given, when his people individually acceded to his covenant, or his faithful servants to the duties of the sanctuary, it was not repeated. It was only when a new promise was made, or an enlargement or an illustration of one formerly made was given, or when, for his Covenant's sake, he denounced wrath on his enemies, that the Lord sware to his people. And the day of conversion, of entering upon office, and ordinary seasons of solemn Covenanting, could not afford such occasions as these. It is in contrast with Christ, the great High Priest of our profession, that those priests are introduced by the apostle, as made without an oath. To the covenant of the Levitical priesthood, the Lord did not append a new and separate oath. The nation of Israel before, by the oath of God, had been set apart as a nation of kings and priests. And when that priesthood was appointed, they merely entered on the enjoyment of privileges formerly promised, and came under renewed obligation to perform appointed duties. But in addition to the oath of God to his Son from eternity, upon the occasion of his taking upon him—in the nature of God-man, the office of His priesthood, in order to show its speciality His oath was also given. There was not the same regard to be paid to the type that belonged to the antitype,—to the priesthood under the law that was due to the priesthood of Christ. The priests under the law were not appointed to their office as if they had been principals. It was reserved for Christ to be so appointed. Perfection was not by the Levitical priesthood. Those priests were made so after the law of a carnal commandment, and hence to the duties of the priesthood by Covenant engagement were pledged. Christ on the other hand, to perform the high functions of his priesthood, was also in solemn covenant voluntarily engaged; but that testimony might be borne to the dignity of his character and perfection of his work, by the oath of God again given, he was made priest. Besides, that oath was sworn to him as not merely a priest, but as the Surety and Mediator of the new covenant. "The Lord sware, and will not repent, Thou art a priest for ever after the order of Melchizedec." And, "by so much was Jesus made a surety of a better testament." To none of the priesthood under the law, did the title of mediator appertain. "But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises."
And through Christ come all the distinguishing features, and all the high privileges of his people, as an holy priesthood. To secure blessings spiritual and eternal to the people of God, the Lord sware to his Son. In what was promised to him by the oath of God, his people—a nation of kings and priests, are interested. He is a king; his people sit down with him on his throne. He is a priest; his people desire to fill up that which is behind of the afflictions of Christ in their flesh, for his body's sake, which is the Church; and while they neither possess nor claim merit on account of their deeds, rejoice inasmuch as they are partakers of Christ's sufferings, that when his glory shall be revealed, they may be glad also with exceeding joy. And by and through the oath by which he was constituted priest, were they in general set apart to their functions,—to covenant, to pray, to praise, to present spiritual sacrifices to God, acceptable through himself. Because of the priesthood of Christ, the priesthood under the law was instituted. Because of the priesthood of Christ, through which was to be ratified God's covenant, his people—a holy priesthood, to act as vowers or Covenanters, were appointed. Their existence, while they claim an interest in its blessings, and resolve and endeavour to perform its duties, testifies to its character and design, and displays how vast was the glory and blessedness that lay couched in the oath of the Father to his incarnate Son. But next, in accordance with the last sign, we have promised as a Covenant sign,
The New Heart. "Behold the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah; not according to the covenant that I made with their fathers, in the day that I took them by the hand, to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord; but this shall be the covenant that I will make with the house of Israel; after those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people." Signally contrasted with the hearts of those of whom it is said, "Yea, they made their hearts as an adamant stone, lest they should hear the law, and the words which the Lord of hosts hath sent in his spirit by the former prophets," the heart thus promised as a new covenant blessing, is essentially a new heart. Unlike the adamant stone, resisting the engraver's chisel, but made soft to receive impressions of truth, it sustains the character of an heart of flesh—substituted for the former, the stony heart. And those blessed with it have had realized to them the promise, "I will give them one heart, and I will put a new spirit within you."
Being a new Covenant blessing, the new heart is a new Covenant sign. A holy priesthood are a people set apart to the service of God. A new heart is the distinguishing feature of those so set apart. Though not palpable to the men of the world, it gives evidence of its own existence, not equivocal; and diffusing its stores, makes known the fountain whence it derived them, and proclaims the end for which its own constitution was given. Like hypocrites in every age, many of the ancient Israelites brake God's covenant, or, in other words, they gave evidence that in his covenant they never had an interest. But the Lord's covenant could not be allowed to fail. Although many disregarded his injunctions, and did their utmost to discredit that covenant, yet that covenant was not to be dishonoured; for in his mercy he should bring again of the Hebrews many to wait on the ordinances of his grace. Under a new dispensation, he should give fresh prominency to spirituality of mind; and by his Spirit, who, as formerly to his people, should write his laws upon their hearts, cause his impressions to remain when the former system of services should have ceased to exist, but where the motives to obedience should, in the preaching of the gospel, be immediately addressed. Various spirits may jointly or successively take possession of those in a state of sin. Yea, the common operations of the Spirit of the Lord, as when the conscience is aroused, and even sometimes his extraordinary operations, may be upon them. But to them meanwhile may not be given the one enduring new heart. To some, as to Balaam, for wise purposes, by the Spirit it may have been given to see a vision of the Almighty; and to others may be given, as God gave to Saul, another heart; and still there may not be bestowed a new heart. To seek this, however, that they may live, and hence, as a Covenant people, serve the Lord, all are thus enjoined,—"Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit: for why will ye die, O house of Israel?"[720]
