To declare the glory of God. All the duty that He requires of man is included in this. Every thing that occurs, independently of the will of moral creatures, is glorifying to God. Every evil thing is overruled for the manifestation of his glory. The willing services of unfallen angels and redeemed men, directly tend to display that glory. All that God requires of man, and consequently the use of all means appointed for glorifying his name, ought to be vowed. By commands to all; by promises, by invitations and encouragements, to his people; by denunciations and warnings addressed to his enemies; he urges men to show forth his glory. To vow and swear to do so is therefore obligatory upon them. The obligation is acknowledged in the Psalmist's vow,—"I will praise thee, O Lord my God, with all my heart; and I will glorify thy name for evermore."[296] And as a consequence of offering worship to God, and therefore, in some instances at least, of vowing to Him, the glorifying of God's name is predicted. "All nations whom thou hast made shall come and worship before thee, O Lord; and shall glorify thy name."[297] But particularly,
To maintain the truth by the profession and practice of it. Idolatry, or the whole of false religion and all its practical consequences, is represented both as a withholding from God of the glory due to him, and as a surrender of the truth.[298] Christ is the Truth; and accordingly those who receive him cleave to his truth by vow and consequent obedience. The Spirit of promise is the Spirit of Truth. They who, by Covenanting, receive him in the former character, accept of him as sent to lead into all truth.[299] The Lord is "a God of Truth." All who take him as their God accede to his truth. It is to the truth of God that those devoted servants, whom he denominates "My Witnesses," give testimony, in their profession, and life, and conversation. It is to his truth that they testify in the same manner, when they act as his "Messenger."[300] The truth of God was committed to his people in the charge which, from time to time, they accepted in Covenanting.[301] The Redeemer commands that it be held fast. "Remember therefore how thou hast received and heard; and hold fast, and repent."[302] The Covenant people of God are "the righteous nation which keepeth the truth."[303] Each of them declares, "I have chosen the way of truth: thy judgments have I laid before me."[304] And each adopts the vow, "I will walk in thy truth."[305]
The truth of God's character ought to be maintained. That his name might be glorified, he was pleased to make himself known. That men might in some measure apprehend him, he revealed himself. That they might not forget but hold communion with him, he appointed the ordinances of his grace. That they might be led to celebrate his greatness, he gave them command and afforded them facilities to pledge themselves to his service. They are called to contemplate with wonder and admiration, the transcendent excellencies of his nature, and to speak of them with reverence and awe. And Himself, whose being and attributes are all infinite, they are created and preserved to praise and adore. The distinct personality of the Father, of the Son, and of the Holy Ghost; the divinity of each of these glorious persons; the unity of the Godhead; and the essential glory of the Three-One-God; are truths implied in the very nature of solemn Covenant engagement; and in order to the keeping of these, require to be held.
The truth of God's government ought to be maintained. The underived majesty of the Eternal; the power and authority of the Father, of the Son, and of the Holy Ghost, extending over all creatures from the beginning to everlasting; the reality and nature of God's purposes, and their fulfilment in creation and providence; in opposition to the atheist, the fatalist, the deist, the sceptic, and every other who does not believe in the truth of Divine revelation; are made known, and claim to be contended for and professed.
The relations of the persons of the ever-blessed Trinity in Unity, confederated in the everlasting Covenant for the salvation of man, behove to be maintained. In the Scriptures, the Father is represented as having given his Son to be a propitiation for the sins of his people, accepted of his work, and conferred upon him a glorious reward;—as the God of grace, calling, justifying, adopting, sanctifying, and receiving to glory, his people;—the Holy Ghost is exhibited as given to the Redeemer, as renewing, illuminating, sanctifying, and comforting his elect, as a Spirit of grace and supplication, as dwelling in their hearts, as given to them as an earnest of the purchased possession, as the Comforter, the Remembrancer, the Spirit of promise;—and the Redeemer is presented as the great Mediator between God and men. To the faith of God's elect, such manifestations are made. They must be confessed.
The mediatorial character and glory of Christ ought to be maintained. The revelation of Divine truth is due to Him as the great Prophet of his Church. He is the great High Priest of his people's profession. He is their King, and Head over all. The illuminating influences of the word and Spirit of Christ have been felt by all his people. They are taught in the Scriptures; they proceed from him as the great Teacher sent from God; they require to be proclaimed.
The atonement and intercession of Christ lie at the foundation of the sinner's hope of acceptance and enjoyment of the favour of God. Being distinctly revealed, like all other doctrines of God's word, they should enter into a testimony for the truth.
The Headship of Christ is a most important part of the truth, to which testimony must be borne. The Father "hath put all things under his feet, and gave him to be head over all things to the church, which is his body, the fulness of him that filleth all in all."[306]
His Headship over the Church is real in every age. In all time, however, by some it has been disputed. It could not be disproved, though it has often been disregarded. So often as the ordinances of Divine grace have been undervalued or misimproved; so often as men have taken upon them to make changes in the worship of God; so often as there have been taught for doctrines the commandments of men; so often as the government which Christ instituted in his house has not been observed; so long as the ordinance of discipline has been neglected or improperly administered; so often as rites and ceremonies in the worship of God have been added or modified according to the caprice of men; so often as men unqualified have assumed to themselves the functions of the ministering servants of Christ; so often as the ministers of religion have acted as lords over God's heritage; so often as one individual in it has sat as head of the Church; so often as one has sat in the temple of God showing himself that he was God; so often as civil rulers have stept out of their own sphere to legislate in the Church, to overrule the proceedings of its courts, to visit with restrictions, whether by pains, or penalties, or otherwise, those who used a lawful power and authority therein; so often and so long as an earthly sovereign has sat as head of any department of His Church; so often and so long, ignorantly or otherwise, has the Redeemer, as King and Head of his Church, been dishonoured. For his glory so set at nought, his people, in protesting against the opposition thereby shown to his just claim, and in maintaining all these claims, are called to testify by vow and oath.
The Headship of Christ over the nations is taught in Divine revelation not less clearly than that over the Church; not less than that, it has been misapprehended and disputed, and often practically denied. But equally with the other, being true, the doctrine has stood unshaken amidst every assault. It is manifest from all the references of Divine truth to civil matters:—from its delineations of the duties of the civil magistrate, and of those under his authority, to Christ and to one another; of the qualifications of lawful civil rulers; of nations as called into existence by the Mediator, under his cognizance, and at his disposal; of the duties of nations to the Church of Christ,—to establish the true religion, restrain ungodliness, and otherwise aid in the promotion of her interests: and appears from designations representing Him as possessed of all power and authority over men. But, even as his authority over the Church, it has been set at nought by many. Civil constitutions not framed according to his law, nor under the care of those impressed with the fear of God; that give equal countenance to error and truth; that support delusive systems, while they do not encourage the spread of truth; that attempt to subordinate the Church to the civil power; that seek the alliance of any idolatrous system of religion to support their authority; that seek the continuance of power by attempting to bring the nations to which they belong, at the risk of the exterminating penalty of poverty or destitution, under the yoke of ignorance, to be fastened on by the educating or training of the young of the lower classes by the priesthood or other agents of the "mystery of iniquity" alone; or that seek to secure their influence by any means at variance with the law of Christ; are all in opposition to his revealed will, are unpossessed of authority from him, are the voluntary agents of "the Prince of the power of the air," and cannot be countenanced without rebellion against Him who is the Governor among the nations. Whosoever there may be that fear God among those who rule or govern in connection with such constitutions, by being connected with them and putting forth their claims, are not in the path of duty. The obligation incumbent on such, nay, on all—whether in power or not, who support them, is either to give up their adherence to them, or to change them so as to bring them up to the scriptural standard. With the supporters of such constitutions unamended, some who disapprove of them, have in some respects to co-operate. But never can any act, without sin, along with these, in such a manner as to recognise the claims of the power maintained by these constitutions, to be the ordinance of God.[307] Joint procedure with such can be warrantable only when directed to an end good in itself, and when accompanied by an expressed or understood disapproval of the character and authority of the civil power. Against such, that they may be modified for good, or succeeded by what is glorifying to God, a substantial testimony ought to be lifted up. In order to the extension of the acknowledgment of the Mediatorial power over all the kingdoms of the world, an exhibition of the prerogatives and claims upon these of the Redeemer, should explicitly be made in testifying for him, by a scriptural profession, and practical observance of his commands. And in solemn Covenanting such attestations required to be embodied. "I will set no wicked thing before mine eyes: I hate the work of them that turn aside; it shall not cleave to me. A froward heart shall depart from me; I will not know a wicked person. Mine eyes shall be upon the faithful of the land, that they may dwell with me: he that walketh in a perfect way, he shall serve me."[308] "I will extol thee, my God, O King; and I will bless thy name for ever and ever." "I will speak of the glorious honour of thy majesty, and of thy wondrous works." "All thy works shall praise thee, O Lord; and thy saints shall bless thee. They shall speak of the glory of thy kingdom, and talk of thy power; to make known to the sons of men his mighty acts, and the glorious majesty of his kingdom. Thy kingdom is an everlasting kingdom, and thy dominion endureth throughout all generations."[309]
