Christ is the same yesterday, today, and forever, as the end which he aims at in his office. His supreme end in it is the glory of God, as particularly in vindicating the honor of his majesty, justice, and holiness, and the honor of his holy law. For this end did he undertake to stand as a Mediator between God and man, and to suffer for men; that the honor of God’s justice, majesty, and law may be vindicated in his sufferings. And he also undertook the office to glorify the free grace of God. And his special end in his undertaking was the salvation and happiness of the elect. These two ends he has in his eye in all parts of the work of his office. And these two ends he unchangeably aims at. These he sought on entering into covenant with the Father from eternity. These he has sought from the beginning of the world to this time, and these he ever will seek. He does not sometimes pursue one end, and then alter his mind and pursue another. But he ever pursues the same ends.
The two unchangeable ends that Christ aims at in His office as Mediator: the glory of God as seen in his justice and the offered free grace, and, the salvation and happiness of the elect. Thus, he reconciled God to man, and man to God. What a Saviour!
