[THE NECESSITY OF HAVING CHRIST FOR OUR ADVOCATE.]
Fifthly, I come now to the fifth thing, which is, to show you what necessity there is that Christ should be our Advocate.
That Christ should be a Priest to offer sacrifice, a King to rule, and a Prophet to teach, all seeing men acknowledge is of necessity; but that he should be an Advocate, a pleader for his people, few see the reason of it. But he is an Advocate, and as an Advocate has a work and employ distinct from his priestly, kingly, or prophetical offices. John says, "He is our Advocate," and signifieth also the nature of his work as such, in that very place where he asserteth his office; as also I have showed you in that which goes before. But having already showed you the nature, I will now show you the necessity of this office.
First. It is necessary for the more full and ample vindication of the justice of God against all the cavils of the infernal spirits. Christ died on earth to declare the justice of God to men in his justifying the ungodly. God standeth upon the vindication of his justice, as well as upon the act thereof. Hence the Holy Ghost, by the prophets and apostles, so largely disputeth for the vindication thereof, while it asserteth the reality of the pardon of sin, the justification of the unworthy, and their glorification with God (Rom 3:24; Isa, Jer, Mal; Rom 3, 4, 8; Gal 3,4). I say, while it disputeth the justness of this high act of God against the cavils of implacable sinners. Now the prophets and apostles, in those disputes by which they seek to vindicate the justice of God in the salvation of sinners, are not only ministers of God to us, but advocates for him; since, as Elihu has it, they "speak on God's behalf," or, as the margin has it, "I will show thee that there are yet words for God," words to be spoken and pleaded against his enemies for the justification of his actions (Job 36:2). Now, as it is necessary that there should be advocates for God on earth to plead for his justice and holiness, while he saveth sinners, against the cavils of an ungodly people, so it is necessary that there should be an Advocate also in heaven, that may there vindicate the same justice and holiness of God from all those charges that the fallen angels are apt to charge it with, while it consenteth that we, though ungodly, should be saved.
That the fallen angels are bold enough to charge God to his face with unjustness of language, is evident in the 1st and 2nd of Job; and that they should not be as bold to charge him with unjustness of actions, nothing can be showed to the contrary. Further, that God seeks to clear himself of this unjust charge of Satan is as manifest; for all the troubles of his servant Job were chiefly for that purpose. And why he should have one also in heaven to plead for the justness of his doing in the forgiveness and salvation of sinners appears also as necessary, even because there is one, even an Advocate with the Father, or on the Father's side, seeking to vindicate his justice, while he pleadeth with him for us, against the devil and his objections. God is wonderfully pleased with his design in saving of sinners; it pleases him at the heart. And since he also is infinitely just, there is need that an Advocate should be appointed to show how, in a way of justice as well as mercy, a sinner may be saved.
The good angels did not at first see so far into the mysteries of the gospel of the grace of God, but that they needed further light therein for the vindication of their Lord as servants. Wherefore they yet did pry and look narrowly into it further, and also bowed their heads and hearts to learn yet more, by the church, of "the manifold wisdom of God" (I Peter 1:12; Eph 3:9,10). And if the standing angels were not yet, to the utmost, perfect in the knowledge of this mystery, and yet surely they must know more thereof than those that fell could do, no wonder if those devils, whose enmity could not but animate their ignorance, made, and do make, their cavils against justice, insinuating that it is not impartial and exact, because it, as it is just, justifieth the ungodly.
That Satan will quarrel with God I have showed you, and that he will also dispute against his works with the holy angels, is more than intimated by the apostle Jude, verse 9, and why not quarrel with, and accuse the justice of God as unrighteous, for consenting to the salvation of sinners, since his best qualifications are most profound and prodigious attempts to dethrone the Lord God of his power and glory.
Nay, all this is evident, since "we have an Advocate with the Father, Jesus Christ the righteous." And again, I say, it is evident that one part of his work as an Advocate, is to vindicate the justice of God while he pleadeth for our salvation, because he pleadeth a propitiation; for a propitiation respects God as well as us; the appeasing his wrath, and the reconciling of his justice to us, as well as the redeeming us from death and hell; yea, it therefore doth the one, because it doth the other. Now, if Christ, as an Advocate, pleadeth a propitiation with God, for whose conviction doth he plead it? Not for God's; for he has ordained it, allows it, and gloriously acquiesces therein, because he knows the whole virtue thereof. It is therefore for the conviction of the fallen angels, and for the confounding of all those cavils that can be invented and objected against our salvation by those most subtle and envious ones. But,
Second. There is matter of law to be objected, and that both against God and us; at least, there seems to be so, because of the sanction that God has put upon the law, and also because we have sinned against it. God has said, "In the day thou eatest thereof, thou shalt surely die"; and, "the soul that sinneth, it shall die." God also standeth still upon the vindication of his justice, he also saveth sinners. Now, in comes our accuser, and chargeth us of sin, of being guilty of sin, because we have transgressed the law. God also will not be put out of his way, or steps of grace, to save us; also he will say, he is just and righteous still. Ay, but these are but say-so's. How shall this be proved? Why, now, here is room for an advocate that can plead to matter of law, that can preserve the sanction of the law in the salvation of the sinner-"He will magnify the law, and make it honourable" (Isa 42:21). The margin saith, "and make him honourable25"—that is, he shall save the sinner, and preserve the holiness of the law, and the honour of his God. But who is this that can do this? "It is the servant of God," saith the prophet, (Isa 42:1, 13), "the Lord, a man of war." But how can this be done by him? The answer is, It shall be done, "for God is well pleased for his righteousness' sake"; for it is by that he magnifies the law, and makes his Father honourable-that is, he, as a public person, comes into the world under the law, fulfills it, and having so done, he gives that righteousness away, for he, as to his own person, never had need thereof; I say, he gives that righteousness to those that have need, to those that have none of their own, that righteousness might be imputed to them. This righteousness, then, he presenteth to God for us, and God, for this righteousness' sake, is well pleased that we should be saved, and for it can save us, and secure his honour, and preserve the law in its sanction. And this Christ pleadeth against Satan as an Advocate with the Father for us; by which he vindicates his Father's justice, holdeth the child of God, notwithstanding his sins, in a state of justification, and utterly overthroweth and confoundeth the devil.
For Christ, in pleading thus, appeals to the law itself, if he has not done it justice, saying, "Most mighty law, what command of thine have I not fulfilled? What demand of thine have I not fully answered? Where is that jot or tittle of the law that is able to object against my doings for want of satisfaction?" Here the law is mute; it speaketh not one word by way of the least complaint, but rather testifies of this righteousness that it is good and holy, (Rom 3:22, 23; 5:15–19). Now, then, since Christ did this as a public person, it follows that others must be justified thereby; for that was the end and reason of Christ's taking on him to do the righteousness of the law. Nor can the law object against the equity of this dispensation of heaven; for why might not that God, who gave the law his being and his sanction, dispose as he pleases of the righteousness which it commendeth? Besides, if men be
