That none ought to be admitted to the privileges of adult persons in the church of Christ, but such as make a profession of real piety.

The covenant to be owned or professed, is God’s covenant, which he has revealed as the method of our spiritual union with him, and our acceptance as the objects of his eternal favour; which is no other than the covenant of grace; at least it is so, without dispute, in these days of the gospel. To own this covenant, is to profess the consent of our hearts to it; and that is the sum and substance of true piety. It is not only professing the assent of our understandings that we understand there is such a covenant, or that we understand we are obliged to comply with it; but it is to profess the consent of our wills, it is to manifest that we do comply with it. There is mutual profession in this affair, a profession on Christ’s part, and a profession on our part; as it is in marriage. And it is the same sort of profession that is made on both sides, in this respect, that each professes a consent of heart. Christ in his word declares an entire consent of heart as to what he offers; and the visible Christian, in the answer that he makes to it in his christian profession, declares a consent and compliance of heart to his proposal. Owning the covenant is professing to make the transaction of that covenant our own. The transaction of that covenant is that of espousals to Christ; on our part, it is giving our souls to Christ as his spouse. There is no one thing that the covenant of grace is so often compared to in Scripture, as the marriage-covenant; and the visible transaction, or mutual profession, there is between Christ and the visible church, is abundantly compared to the mutual profession there is in marriage. In marriage the bride professes to yield to the bridegroom’s suit, and to take him for her husband, renouncing all others, and to give up herself to him to be entirely and for ever possessed by him as his wife. But he that professes this towards Christ, professes saving faith. They that openly covenanted with God according to the tenor of the institution, Deut. x. 20.. visibly united themselves to God in the union of that covenant. They professed on their parts the union of the covenant of God, which was the covenant of grace. It is said in the institution, “Thou shalt cleave to the Lord, and swear by his name;” or as the words more literally are, “Thou shalt unite unto the Lord, and swear into his name.” So in Isaiah lvi.. it is called a “joining themselves to the Lord.” But the union, cleaving, or joining of that covenant, is saving faith, the grand condition or the covenant of Christ, by which we are in Christ. This is what [on our part] brings us into the Lord. For a person explicitly or professedly to enter into the union or relation of the covenant of grace with Christ, is the same as professedly to do that which on our part is the uniting act, and that is the act of faith. To profess the covenant of grace, is to profess it, not as a spectator, but as one immediately concerned in the affair, as a party in the covenant professed; and this is to profess that in the covenant which belongs to us as a party, or to profess our part in the covenant; and that is the soul’s believing acceptance of the Saviour. Christ’s part is salvation, our part is a saving faith in him; not a feigned, but unfeigned faith; not a common, but special and saving faith; no other faith is the condition of the covenant of grace.

I know the distinction made by some, between the internal and external covenant; but, I hope, the divines that make this distinction, would not be understood, that there are really and properly two covenants of grace; but only that those who profess the one only covenant of grace, are of two sorts. There are those who comply with it internally and really, and others who do so only externally, that is, in profession and visibility. But he that externally and visibly complies with the covenant of grace, appears and professes to do so really.—There is also this distinction concerning the covenant of grace; it is exhibited two ways, the one externally, by the preaching of the word, the other internally and spiritually, by enlightening the mind rightly to understand the word. But it is with the covenant, as it is with the call of the gospel: he that really complies with the external call, has the internal call; so he that truly complies with the external proposal of God’s covenant, as visible Christians profess to do, does indeed perform the inward condition of it. But the New Testament affords no more foundation for supposing two real and properly distinct covenants of grace, than it does to suppose two sorts of real Christians.

When those persons who were baptized in infancy properly own their baptismal covenant, the meaning is, that they now, being capable to act for themselves, do professedly and explicitly make their parents’ act, in giving them up to God, their own, by expressly giving themselves up to God. But this no person can do, without either being deceived, or dissembling and professing what he himself supposes to be a falsehood, unless he supposes that in his heart he consents to be God’s. A child of christian parents never does that for himself which his parents did for him in infancy, till he gives himself wholly to God. But surely he does not do it, who not only keeps back a part, but the chief part, his heart and soul. He that keeps back his heart, does in effect keep back all; and therefore, if he be sensible of it, is guilty of solemn wilful mockery, if at the same time he solemnly and publicly professes that he gives himself up to God. If there are any words used by such, which in their proper signification imply that they give themselves up to God; and if these words, as they intend them to be understood, and as they are understood by those that hear them, according to their established use and custom among that people, do not imply, that they do it really, but do truly reserve or keep back the chief part; it ceases to be a profession of giving themselves up to God, and so ceases to be a professed covenanting with God. The thing which they profess belongs to no existing covenant of God; for God has revealed no such covenant, in which our transacting of it is a giving up ourselves to him with reserve, or holding back our souls, our chief part, and in effect our all. And therefore, although such public and solemn professing may be a very unwarrantable and great abuse of words, and taking God’s name in vain, it is no professed covenanting with God.
