Jesus “came into the world for the express purpose of vindicating his Father's law” (LP 30.3).

“Christ came to earth to maintain and exalt the divine law, by himself suffering the penalty of sin, and to thereby evidence that God will in no wise clear the guilty…. his mission to earth was to vindicate the supreme law of God, not to annul it.” (ST March 7, 1878, par. 16).

Christ volunteered to maintain and vindicate the holiness of the divine law. Con 20.2

And thus Christ would fully vindicate His Father’s law. Con 21.3

The only-begotten Son of God accepts all the liabilities that fall upon the transgressor of the law, vindicates its unchangeable and holy character. The death of Christ removes every argument that Satan could bring against the precepts of Jehovah. (ST February 5, 1894, par. 10).

But it is ever the purpose of Satan to make void the law of God and to pervert the true meaning of the plan of salvation. … The atonement of Calvary vindicated the law of God as holy, just, and true, not only before the fallen world but before heaven and before the worlds unfallen. Christ came to magnify the law and to make it honorable. (FW 118.2).

The final judgment is a most solemn, awful event. … God will be honored and His government vindicated and glorified, and that in the presence of the inhabitants of the unfallen worlds. On the largest possible scale will the government of God be vindicated and exalted. (21MR 349.1).
