(1.) That in human covenants, in which things are promised on certain conditions, these conditions are supposed to be possible to be performed, otherwise the promise, depending thereon, is rendered void, and it contains no other than a virtual denial to make it good. Thus the king of Israel did not, at first, understand the message sent him by the king of Syria, requiring of him to heal Naaman of his leprosy, as a condition of peace and friendship between them; and the inference he makes from it was, that he had a design to seek a quarrel against him; and his reasoning would have been just, had it been intended in this sense, since the condition was not in his own power. Moreover, if a master should tell his servant, that he would give him a reward, in case he would perform the work of ten days in one, he would conclude nothing else from it, but that he was resolved not to give him any thing. Now, to apply this to our present purpose, we must consider whether faith, when it is a condition of the covenant of grace, be in our own power or no. There are some external acts thereof, indeed, which are so; but these are too low to be deemed conditions of salvation, or of the blessings of the covenant of grace; and as for those acts which are supernatural, or the effects of the exceeding greatness of the power of God, though they are inseparably connected with salvation, yet they are not in our power; so as that we may conclude, that they are proposed as conditions, in the same sense as those things are said to be, that are supposed to contain this ingredient in them.
In this respect, the covenant of grace, as to the conditionality of it, differs from the covenant of innocency, in which perfect obedience, which was the condition thereof, was so far in man’s power, that he could have performed it, without the superadded assistance of divine grace: but when, on the other hand, perfect obedience is considered, as a condition of fallen man’s entering into life, in which sense our Saviour’s reply to the young man’s question, in Matt. xix. 17. is understood by many, this is a plain intimation that eternal life is not to be obtained this way, inasmuch as the condition is impossible.
(2.) When conditions are insisted on, in human covenants, it is generally supposed, that though it be possible for the person, that enjoins them, to assist, and enable him, who is under this obligation, to perform them, yet he will not give him that assistance; for, if he does, the contract can hardly be reckoned conditional, but absolute: thus if a creditor should tell an insolvent debtor, that he will discharge him, provided he pays the debt, and, at the same time, gives him to understand that he will supply him with a sum of money, that shall enable him to do it, this is altogether the same as though he had discharged him, without any conditional demand of payment. This I cannot but mention, because there are some persons, who speak of faith, as a condition of the covenant of grace, and, at the same time, take it for granted, that it is not in our own power to perform it: nevertheless, since God has promised that he will work it in us, they conclude it to be conditional; whereas such a promise as this would render the covenant absolute, or, at least, not conditional, in the same sense, in which human covenants are, and only infer what we do not deny, that there is a necessary connexion between that grace, which God will enable us to perform, and salvation, which he has promised in this covenant.
(3.) When any thing is promised to another, on condition that he do what is enjoined on him, it is generally supposed that it is a dubious and uncertain matter whether this condition shall be fulfilled, and the promise take place; or, as I may express it, every condition contains not a necessary, but an uncertain connexion between the promised advantage, and the duty enjoined, and that for this reason, because all human covenants depend on the power and will of men, who are under conditional engagements to perform what is demanded therein; and these are supposed to be mutable and defective, and, as far as they are so, the performance of the condition may be reckoned dubious; and he that made the promise is liable to the same uncertainty, whether he shall make it good or no. This will hardly be denied, by those who defend the other side of the question, who, in explaining the nature of human liberty, generally suppose, that every one, who acts freely, might do the contrary; therefore they must, from hence, conclude, that, if the performing the conditions of a covenant be the result of man’s free will, it is possible for him not to perform them, and therefore it must be a matter of uncertainty, whether a person, who promises a reward upon the performance of these conditions, will confer it or no. But, however this may be applied to human covenants, we are not to suppose that faith, or any other grace, is, in this respect, a condition of the covenant of grace, as though God’s conferring the blessings promised therein were dependent on the will of man, as determining itself to the exercise of these graces; in this respect, we cannot but deny the covenant of grace to be conditional.
(4.) If we take an estimate of the worth and value of a condition enjoined, the advantages that he, who enjoins it, expects to receive from it, or the reference that the performance thereof has to the procuring the blessing promised, in which case the person, who has fulfilled it, may be said to merit, or have whereof to glory in himself, as to what concerns the part he has performed therein: this must not be applied to any transaction between God and man, and therefore is wholly to be excluded from those ideas, which are contained in the word condition, when applied to the covenant of grace, as will be allowed by most, who do not give into the Popish doctrine of the merit of good works. Concerning the worth and value of faith, and all other graces, I would not be thought, in the least, to depreciate or divest them of that excellency, which they have, above all other effects of God’s power and blessings of providence; whereas certainly we ought to bless God for them, or glory in him, as the Author of them: but that which we would fence against in this matter, is nothing more than what our Saviour does, when he says, When ye shall have done all those things which are commanded you, say, We are unprofitable servants, Luke xvii. 10. And I would not have any one suppose, that whatever condition is performed by us, has such a value put on it, as that eternal life is hereupon due to us, in a way of debt, which would make way for boasting. It is true, the conditions which Christ performed in that branch of the covenant, which more immediately respected himself, which some call the covenant of redemption, were properly meritorious, and the blessings he purchased thereby were given him in a way of debt, and not as an undeserved favour: but, if we suppose that there is the same reference of faith, or any other grace acted by us, to that salvation, which we expect, we turn the covenant of grace into a covenant of works, and resolve that into ourselves which is due to God alone.
But since many excellent divines have asserted faith to be a condition of the covenant of grace, who do not understand the word condition, either as containing in it any thing dubious or uncertain on the one hand, or meritorious on the other; and probably they choose to express themselves so, in compliance with custom, and to explain away the common ideas of the word condition, as applied to human covenants, rather than altogether to lay it aside; and, it may be, they do this, lest they should be thought to deny the necessary connexion between faith and salvation: I shall therefore, for the same reason, conclude this head with the following propositions, whereby our not using the word condition, may be vindicated, from any just exception; or, our using of it may not appear to be inconsistent with the divine perfections, or the grace of this covenant. Therefore,
1st, We shall lay down this as an undoubted truth, the denial whereof would be subversive of all religion, that faith, and all other graces, are required by God, and our obligation thereunto is indispensible; whether it be reckoned a condition of the covenant or no, it is no less a duty.[[100]] It is true, there are some who distinguish between the obligation of a law, and that of a covenant; the former of which depends on an express command; the latter is the result of some blessings promised or conferred, which has in it the obligation of a law, but not the formal nature of it; and therefore they conclude, that we are commanded by God, as a Lawgiver, to believe and repent, but that it is more proper to say, we are rather engaged by him, as a covenant-God, than commanded to exercise these graces: but this dispute is rather about the propriety of words, than the main substance of the doctrine itself; and therefore I shall enter no farther into this critical enquiry, but content myself with the general assertion, that faith, and all other graces are necessary duties; without which, it is impossible to please God, to use the apostle’s expression, Heb. xi. 6. or to have any right to the character of Christians.
2dly, Faith, and all other graces, are to be also considered as blessings, promised in the covenant of grace. This appears from those scriptures that speak of them as the gifts of God, Eph. ii. 8. purchased by the blood of Christ, and so founded on his righteousness, 2 Pet. i. 1. and wrought in us by his Spirit, and the exceeding greatness of his power, Eph. i. 19. and as discriminating blessings, which all are not partakers of, as the apostle says, All men have not faith, 2 Thess. iii. 2.
This may be farther argued, from what Christ undertook to purchase for, and apply to his people, as their federal Head; so that, in pursuance hereof, all spiritual blessings in heavenly things, are bestowed on them, in him; and hereby the covenant is made good to them, as God is said, together with Christ, to give them all things, Rom. viii. 32. First, Christ is given for a covenant of his people, and then, upon his fulfilling what he undertook to procure for them, all that grace, which is treasured up in him, is applied to them; therefore faith, and other concomitant graces, are covenant-blessings.
3dly, There is a certain connexion between faith, with other concomitant graces, and salvation. But this having been considered elsewhere, together with the sense of those scriptures, that seem to be laid down in a conditional form, from whence the arguments, to prove the conditionality of the covenant of grace, are generally taken;[[101]] all that we shall add, at present, is, that since, in this eternal covenant between the Father and the Son, it was agreed, established, and, on our Saviour’s part, undertaken, that the elect should be not only redeemed, but sanctified, and enabled to exercise all grace, before they are brought to glory, this is made good to them in this covenant; and therefore, as the consequence of Christ’s purchase, faith, and all other graces, are wrought in the soul, which afterwards, in receiving the end of faith, is brought to eternal salvation; so that we may as well separate Christ’s undertaking to redeem his people from their attaining salvation, as we can his applying those graces which accompany it.
