When we speak of a cause, we speak not of a person simply as so considered; for, as I said before, person and cause must be distinguished; nor can the person make the cause good but as he regulates his action by the Word of God. If, then, a good, a righteous, man doth what the law condemns, that thing is bad; and if he be indicted for so doing, he is indicted for a bad cause; and he that will be his advocate, must be concerned in and about a bad matter; and how he will bring his client off, therein doth lie the mystery.
I know that a bad man may have a good cause depending before the judge, and so also good men have (Job 31). But then they are bold in their own cause, and fear not to make mention of it, and in Christ to plead their innocency before the God of heaven, as well as before men (Psa 71:3-5. II Cor 1:23. Gal 1:10. Phil 1:8). But we have in the text a cause that all men are afraid of-a cause that the apostle concludes so bad that none but Jesus Christ himself can save a Christian from it. It is not only sinful, but sin itself-“If any man sin, we have an Advocate with the Father.”
Wherefore there is in this place handled by the apostle, one of the greatest mysteries under heaven-to wit, that an innocent and holy Jesus should take in hand to plead for one before a just and righteous God, that has defiled himself with sin; yea, that he should take in hand to plead for such an one against the fallen angels, and that he should also by his plea effectually rescue, and bring them off from the crimes and curse whereof they were verily guilty by the verdict of the law, and approbation of the Judge.
This, I say, is a great mystery, and deserves to be pried into by all the godly, both because much of the wisdom of heaven is discovered in it, and because the best saint is, or may be, concerned with it. Nor must we by any means let this truth be lost, because it is the truth; the text has declared it so, and to say otherwise is to belie the Word of God, to thwart the apostle, to soothe up hypocrites, to rob Christians of their privilege, and to take the glory from the head of Jesus Christ (Luke 18:11,12).
The best saints are most sensible of their sins, and most apt to make mountains of their mole hills. Satan also, as has been already hinted, doth labour greatly to prevail with them to sin, and to provoke their God against them, by pleading what is true, or by surmising evilly of them, to the end they may be accused by him (Job 2:9). Great is his malice toward them, great is his diligence in seeking their destruction; wherefore greatly doth he desire to sift, to try, and winnow them, if perhaps he may work in their flesh to answer his design-that is, to break out in sinful acts, that he may have by law to accuse them to their God and Father. Wherefore, for their sakes this text abides, that they may see that, when they have sinned, “they have an Advocate with the Father, Jesus Christ the righteous.” And thus have I showed you the nature, the order, and occasion of this office of our blessed Lord Jesus.
[HOW CHRIST MANAGES THE OFFICE OF AN ADVOCATE.]
II. I come now to show you how Jesus Christ doth manage this his office of an Advocate for us. And that I may do this to your edification, I shall choose this method for the opening of it-First. Show you how he manages this office with his Father. Second. I shall show you how he manages it before him against our adversary.
First. How he manages this his office of Advocate with his Father.
1. He doth it by himself, by no other as deputy under him, no angel, no saint; no work has place here but Jesus, and Jesus only. This the text implies: “We have an Advocate”; speaking of one, but one, one alone; without an equal or an inferior. We have but one, and he is Jesus Christ. Nor is it for Christ’s honour, nor for the honour of the law, or of the justice of God, that any but Jesus Christ should be an Advocate for a sinning saint. Besides, to assert the contrary, what doth it but lessen sin, and make the advocateship of Jesus Christ superfluous? It would lessen sin should it be removed by a saint or angel; it would make the advocateship of Jesus Christ superfluous, yea, needless, should it be possible that sin could be removed from us by either saint or angel.
Again; if God should admit of more advocates than one, and yet make mention of never an one but Jesus Christ; or if John should allow another, and yet speak nothing but of Jesus only; yea, that an advocate under that title should be mentioned but once, but once only in all the book of God, and yet that divers should be admitted, stands neither with the wisdom or love of God, nor with the faithfulness of the apostle. But saints have but one Advocate, if they will use him, or improve their faith in that office for their help, so; if not, they must take what follows. This I thought good to hint at, because the times are corrupt, and because ignorance and superstition always wait for a countenance with us, and these things have a natural tendency to darken all truth, so especially this, which bringeth to Jesus Christ so much glory, and yieldeth to the godly so much help and relief.
