Q. 31. With whom was the covenant of grace made?
A. The covenant of grace was made with Christ as the second Adam, and in him with all the elect as his seed.
Q. 32. How is the grace of God manifested in the second covenant?
A. The grace of God is manifested in the second covenant, in that he freely provideth and offereth to sinners a Mediator, and life and salvation by him; and requiring faith as the condition to interest them in him, promiseth and giveth his Holy Spirit to all his elect, to work in them that faith, with all other saving graces; and to enable them unto all holy obedience, as the evidence of the truth of their faith and thankfulness to God, and as the way which he hath appointed them to salvation.
Q. 33. Was the covenant of grace always administered after one and the same manner?
A. The covenant of grace was not always administered after the same manner, but the administrations of it under the Old Testament were different from those under the New.
Q. 34. How was the covenant of grace administered under the Old Testament?
A. The covenant of grace was administered under the Old Testament, by promises, prophecies, sacrifices, circumcision, the passover, and other types and ordinances, which did all fore-signify Christ then to come, and were for that time sufficient to build up the elect in faith in the promised Messiah, by whom they then had full remission of sin, and eternal salvation.
Q. 35. How is the covenant of grace administered under the New Testament?
A. Under the New Testament, when Christ the substance was exhibited, the same covenant of grace was and still is to be administered in the preaching of the Word, and the administration of the sacraments of Baptism and the Lord’s Supper; in which grace and salvation are held forth in more fulness, evidence, and efficacy, to all nations.
Q. 36. Who is the Mediator of the covenant of grace?
A. The only Mediator of the covenant of grace is the Lord Jesus Christ, who, being the eternal Son of God, of one substance and equal with the Father, in the fulness of time became man, and so was and continues to be God and man, in two entire distinct natures, and one person, forever.
Q. 37. How did Christ, being the Son of God, become man?
A. Christ the Son of God became man, by taking to himself a true body, and a reasonable soul, being conceived by the power of the Holy Ghost in the womb of the virgin Mary, of her substance, and born of her, yet without sin.
Q. 38. Why was it requisite that the Mediator should be God?
A. It was requisite that the Mediator should be God, that he might sustain and keep the human nature from sinking under the infinite wrath of God, and the power of death, give worth and efficacy to his sufferings, obedience, and intercession; and to satisfy God’s justice, procure his favour, purchase a peculiar people, give his Spirit to them, conquer all their enemies, and bring them to everlasting salvation.
Q. 39. Why was it requisite that the Mediator should be man?
A. It was requisite that the Mediator should be man, that he might advance our nature, perform obedience to the law, suffer and make intercession for us in our nature, have a fellow-feeling of our infirmities; that we might receive the adoption of sons, and have comfort and access with boldness unto the throne of grace.
Q. 40. Why was it requisite that the Mediator should be God and man in one person?
A. It was requisite that the Mediator, who was to reconcile God and man, should himself be both God and man, and this in one person, that the proper works of each nature might be accepted of God for us, and relied on by us as the works of the whole person.
 Galatians 3:16. Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. Romans 5:15-21. But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. And not as it was by one that sinned, so is the gift: for the judgment was by one to condemnation, but the free gift is of many offences unto justification. For if by one man’s offence death reigned by one; much more they which receive abundance of grace and of the gift of righteousness shall reign in life by one, Jesus Christ.) Therefore as by the offence of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life. For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous. Moreover the law entered, that the offence might abound. But where sin abounded, grace did much more abound: That as sin hath reigned unto death, even so might grace reign through righteousness unto eternal life by Jesus Christ our Lord. Isaiah 53:10-11. Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand. He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.

 2 Corinthians 3:6-9. Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life. But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away: How shall not the ministration of the spirit be rather glorious? For if the ministration of condemnation be glory, much more doth the ministration of righteousness exceed in glory.
