Exposition

We have now shown what kind of a Mediator it is necessary for us to have. The next question which claims our attention is, Who is this Mediator? That this Mediator is Jesus Christ, the Son of God, manifested in the flesh, is proven by these considerations:

1. It became the Mediator to be very God, as has been shown. God the Father, however, could not be the Mediator; because he does not work through himself, but through the Son, and the Holy Ghost. Neither is the Father a messenger; because he is sent by no one, but himself sends the Mediator. Nor could the Holy Ghost be the Mediator; because he was to he sent by the Mediator into the hearts of the elect. Therefore, the Son alone is this Mediator.

2. It was necessary that the Mediator should have that which it became him to confer upon us. It became him, now, to confer upon us the right and title of the sons of God, which we had forfeited; that is, it became him to bring it to pass, that God might, for his Son's sake, adopt us as his children. This, however, Christ alone was able to effect, because he alone had the right thereof. The Holy Ghost had not this right, because he is not the Son. Neither did it belong to the Father, for the same reason; and also because it became him to adopt us among his children, through the Son. Therefore, the Word, who is the natural Son of God, is alone our Mediator, in whom, as in the first begotten, we are adopted as the Sons of God, as it is said: "If the Son shall make you free, ye shall be free indeed." "As many as received him, to them he gave the power to be called the sons of God." "Unto the adoption of children by Jesus Christ." "He hath made us to be accepted in the Beloved." (John 8:36; 1:12. Eph. 1:5-6.)

3. The Son, alone, is the Word, the Ambassador of the Father, and that person who was sent to the human race, to reveal the will of God, through whom the Father operates and gives the Holy Spirit; and through whom, also, the second creation is accomplished; for it is through the Son that we are made new creatures. The Scriptures, for this reason, every where join the first and second creation, because the second was to be effected by the same person through whom the first was made. "All things were made by the Son." (John 1:3.) The Mediator was also to be a Messenger, and Peace-maker, between God and us, and to regenerate us by the Holy Spirit. Therefore, the Son alone is this Mediator.

4. It belongs to the Mediator to send immediately the Holy Spirit. But it is the Son alone who thus sends the Holy Spirit. The Father does, indeed, send the Holy Spirit, but it is through the Son. The Son sends the Spirit immediately from the Father, as he himself declares: "Whom I will send unto you from the Father." (John 15:26.)
5. It became the Mediator to suffer and die. But it was not possible for any of the persons of the Godhead to suffer and die, except the Son, who assumed our nature. "God was manifested in the flesh." " Christ was put to death in the flesh." (1 Tim. 3:16. 1 Pet. 3:18.) Therefore, the Son is the Mediator.

6. That the Son is the Mediator may be proven by a comparison of the prophecies of the Old Testament with their fulfillment in the New Testament.

7. The works and miracles of Christ establish his claims to the office of Mediator. " The works that I do, bear witness of me, that the Father hath sent me." "Believe the works." "When Christ will come, he will do more miracles than these." "Go and shew John those things which ye do hear and see. The blind receive their sight," &c. (John 5:36; 10:38; 7:31. Matt. 11:4-5.)
8. By these clear testimonies of Scripture: "There is one Mediator between God and man, the man Christ Jesus." "Christ is made unto us of God, wisdom, righteousness, sanctification, and redemption ;" that is, he is made unto us a teacher of wisdom, a justifier, a sanctifier, and a redeemer; which is the same as to say he is a Mediator and Saviour, both by his merit and efficacy; for in this declaration of the Apostle, the abstract is put for the concrete. (1 Tim. 2:5. 1 Cor. 1:30.)

It is here worthy of notice that the Mediator is said to be made unto us of God; which means that he was appointed and given. The Mediator ought to have been given by us, and to have proceeded from us, because we had sinned. But we were not able to give a Mediator, in as much as we were all the children of wrath. Therefore, it was necessary that he should be given unto us of God.

It is also worthy of notice that righteousness and holiness were one and the same thing in us before the fall, viz: an inherent conformity with God and the divine law, as they are now the same thing in the holy angels. Since the fall, however, they are not the same thing in us. For, now, Christ is our righteousness; and our justification consists in the imputation of his righteousness, by which we are accounted just before God. Holiness is the beginning of our conformity with God, whilst sanctification is the carrying forward of this conformity with God, which in this life is imperfect, but which will be fully perfected in the life to come; when righteousness and holiness will again be the same thing in us, as they are now in the holy angels. The sum and substance of the whole doctrine of the Mediator is contained in what now follows.
