And thus far, there is, in some way, a harmony between his being a sacrifice, a priest, and an Advocate. As a sacrifice, our sins were laid upon him (Isaiah 53). As a priest, he beareth them (Exo 28:38). And as an Advocate, he acknowledges them to be his own (Psa 69:5). Now, having acknowledged them to be his own, the quarrel is no longer between us and Satan, for the Lord Jesus has espoused our quarrel and made it his. All, then, that we in this matter have to do is stand at the bar by faith among the angels and see how the business goes. O blessed God! What a lover of mankind art thou! and how gracious is our Lord Jesus, in his thus managing matters for us?
(2.) The Lord Jesus, having thus taken our sins upon himself, next pleads his own goodness to God on our behalf, saying, "Let not those that wait on thee, O Lord God of hosts, be ashamed for my sake; let not those that seek thee be confounded for my sake, O God of Israel, because for thy sake I have borne reproach; shame hath covered my face" (Psa 69:6, 7). Mark, let them not be ashamed for my sake; let them not be confounded for my sake. Shame and confusion are the fruits of guilt, or of a charge for sin, (Jer 3:25), and are but an entrance into condemnation (Dan 12:2. John 5:29). But behold how Christ pleads, saying, Let not that be for my sake, for the merit of my blood, for the perfection of my righteousness, for the prevalency of my intercession. Let them not be ashamed for my sake, O Lord God of hosts. And let no man object, because this text is in the Psalms as if it were not spoken by the prophet of Christ; for both John and Paul, yea, and Christ himself, do make this psalm a prophecy of him. Compare verse with John 2:17, and with Romans 15:3; and verse 21 with Matthew 27:48, and Mark 15:25. But is not this a wonderful thing, that Christ should first take our sins, and account them his own, and then plead the value and worth of his whole self for our deliverance? For by these words, "for my sake," he pleads his own self, his whole self, and all that he is and has; and thus he put us in good estate again, though our cause was very bad.
To bring this down to weak capacities Suppose a man should be indebted twenty thousand pounds, but has not twenty thousand farthings wherewith to pay; and suppose also that this man be arrested for this debt, and that the law also, by which he is sued, will not admit of penny bate; this man may yet come well enough off if his advocate or attorney will make the debt his own and will, in the presence of the judges, out with his bags, and pay down every farthing. Why, this is the way of our Advocate. Our sins are called debts (Matt 6:12). We are sued for them at the law (Luke 12:59). And the devil is our accuser; but behold, the Lord Jesus comes out with his worthiness, pleads it at the bar, making the debt his own (Mark 10:45. II Cor 3:5). And saith, Now let them not be ashamed for my sake, O Lord God of hosts: let them not be confounded for my sake, O God of Israel. And hence, as he is said to be an Advocate, so he is said to be a propitiation, or amends-maker, or one that appeaseth the justice of God for our sins-"If any man sin, we have an Advocate with the Father, Jesus Christ the righteous; and he is the propitiation for our sins."
And who can now object against the deliverance of the child of God? God cannot; for he, for Christ's sake, according as he pleaded, hath forgiven us all trespasses (Col 2:13, Eph 4:32). The devil cannot; his mouth is stopped, as is plain in the case of Joshua (Zech 3). The law cannot; for that approveth of what Christ has done. This, then, is the way of Christ's pleading. You must know, that when Christ pleads with God, he pleads with a just and righteous God, and therefore he must plead law, and nothing but law; and this he pleaded in both these pleas-First, in confessing of the sin he justified the sentence of the law in pronouncing of it evil; and then in his laying of himself, his whole self, before God for that sin, he vindicated the sanction and perfection of the law. Thus, therefore, he magnifies the law, and makes it honorable, and yet brings off his client safe and sound in the view of all the angels of God.
