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,[144] give worth and efficacy to his sufferings, obedience, and intercession;[145] and to satisfy God's justice,[146] procure his favour,[147] purchase a peculiar people,[148] give his Spirit to them,[149] conquer all their enemies,[150] and bring them to everlasting salvation.[151]

[144] Acts 2:24-25. Whom God hath raised up, having loosed the pains of death: because it was not possible that he should be holden of it. For David speaketh concerning him, I foresaw the Lord always before my face, for he is on my right hand, that I should not be moved.

Hebrews 7:25-28. Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them. For such an high priest became us, who is holy, harmless, undefiled, separate from sinners, and made higher than the heavens; Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself. For the law maketh men high priests which have infirmity; but the word of the oath, which was since the law, maketh the Son, who is consecrated for evermore.

[146] Romans 3:24-26. Being justified freely by his grace through the redemption that is in Christ Jesus: Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus.

[147] Ephesians 1:6. To the praise of the glory of his grace, wherein he hath made us accepted in the beloved.

[148] Titus 2:13-14. Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.

[149] Galatians 4:6. And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.

[150] Luke 1:68-69, 71, 74. Blessed be the Lord God of Israel; for he hath visited and redeemed his people, And hath raised up an horn of salvation for us in the house of his servant David;... That we should be saved from our enemies, and from the hand of all that hate us;... That he would grant unto us, that we being delivered out of the hand of our enemies might serve him without fear.

[151] Hebrews 5:8-9. Though he were a Son, yet learned he obedience by the things which he suffered; And being made perfect, he became the author of eternal salvation unto all them that obey him.

Hebrews 9:11-15. But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building; Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us. For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God? And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
