1. He pleads against him the well-pleasedness that his Father has in his merits, saying, This shall please the Lord, or this doth or will please the Lord, better than anything that can be propounded (Psa 69:31). Now that this plea is true, as it is established upon the liking of God Almighty, whatever Satan can say to obtain our everlasting destruction is without ground and so unreasonable. "I am well pleased," saith God (Matt 3:17), and again, "The Lord is well pleased for his (Christ's) righteousness' sake" (Isa 42:21). All those who take actions against others pretend that wrong is done, either against themselves or against the king. Now Satan will never enter an action against us in the court above, for that wrong by us has been done to himself; he must pretend, then, that he sues us, for that wrong has, by us, been done to our king. But, behold, "We have an Advocate with the Father," and he has made compensation for our offenses. He gave himself for our offenses. But still, Satan maintains his suit, and our God, saith Christ, is well pleased with us for this compensation's sake, yet he will not leave off his clamor. Come, then, says the Lord Jesus, the contention is not now against my people but against myself and about the sufficiency of the amends that I have made for the transgressions of my people; but he is near that justifies me, that approves and accepts of my doings; therefore, shall I not be confounded? Who is my adversary? Let him come near me! Behold, "the Lord God will help me" (Isa 50:7-9). Who is he who condemns me? Lo, they all shall, were there ten thousand times as many more of them, wax old as a garment; the moth shall eat them up. Wherefore, if the Father saith Amen to all this, as I have shown already that he hath and doth, the which also further appeareth, because the Lord God has called him the Saviour, the Deliverer, and the Amen; what follows, but that a rebuke should proceed from the throne against him? And this, indeed, our Advocate calls for from the hand of his Father, saying, O enemy, "the Lord rebuke thee"; yea, he doubles this request to the judge, to intimate his earnestness for such a conclusion, or to show that the enemy shall surely have it, both from our Advocate, and from him before whom Satan has so grievously accused us (Zech 3).
For what can be expected to follow from such an issue in law as this is, but sound and severe snibs from the judge upon him that hath thus troubled his neighbor, and that hath, in the face of the country, cast contempt upon the highest act of mercy, justice, and righteousness, that ever the heavens beheld? 6 And all this is true with reference to the case in hand, wherefore, "The Lord rebuke thee," is that which, in conclusion, Satan must-have for the reward of his works of malice against the children and for his contemplation of the works of the Son of God. Now, our Advocate having thus established, by the law of heaven, his plea with God for us against our accuser, there is a way made for him to proceed upon a foundation that cannot be shaken; therefore, he proceeds in his plea and further urges against this accuser of the brethren.
2. God's interest in these people, and pray that God will remember that: "The Lord rebuke thee, O Satan; the Lord that hath chosen Jerusalem, rebuke thee." True, the church, the saints, are despicable in the world; wherefore men do think to tread them down; the saints are, also, weak in grace, but have corruptions that are strong, and, therefore, Satan, the god of this world, doth think to tread them down; but the saints have a God, the living, the eternal God, and, therefore, they shall not be trodden down; yea, they "shall be held up, for God is able to make them stand" (Rom 14:4).
It was Haman's mishap to be engaged against the queen and the kindred of the queen; it was that that made him he could not prosper; that brought him to contempt and the gallows. Had he sought to ruin other people, he probably might have brought his design to a desired conclusion, but his compassing the death of the queen spoiled all. Satan, also, when he fighteth against the church, must be sure to come to the worst, for God has a concern in that; therefore, it is said, "The gates of hell shall not prevail against it," but this hindereth not, but that he is permitted to make almost what spoils his will of those that do not belong to God. Oh, how many doth he accuse, and soon get out from God, against them, a license to destroy them! as he served Ahab, and many more. But this, I say, is a very great block in his way when he meddles with the children; God has an interest in them. Has God cast away his people? God forbid!" (Rom 11:1,2). The text intimates that they for sin had deserved it and that Satan would fain have had it had been so, but God's interest in them preserved them: God hath not cast away his people, which he foreknew." Therefore, when Satan accuses them before God, Christ, as he pleaded for his own worth and merit, also against him, that interest that God has in them.
And though this, to some, may seem an indifferent plea, for what engagement lieth, may they say, upon God to be so much concerned with them, for they sin against him and often provoke him most bitterly? Besides, in their best state, they are altogether vanity and a very thing of naught: What is man (sorry, man), that thou art mindful of him," or that thou shouldest be so?
