But the plan of redemption had a yet broader and deeper purpose than the salvation of the human race. It was not merely that the inhabitants of this little world might respect the law of God as it should be respected, but it was to vindicate the character of God before the universe. The Savior looked forward to this when, just before His crucifixion, He said: “Now is the judgment of this world; now the ruler of this world will be cast out. And I, if I am lifted up from the earth, will draw all peoples to Myself” (John 12:31, 32). Christ dying for the salvation of humanity would justify God and His Son in their dealing with the rebellion of Satan, establish the law of God, and reveal the nature and results of sin.BOE 24.6

From the beginning, the great controversy had been over the law of God. Satan had sought to prove that God was unjust, His law faulty, and that the good of the universe required it to be changed. In attacking the law he aimed to overthrow the authority of God, its Author.BOE 25.1

When Satan overcame Adam and Eve, he thought he had gained possession of this world, “because,” he said, “they have chosen me as their ruler.” He claimed it was impossible for forgiveness to be granted; the fallen race were his rightful subjects, and the world was his. But God gave His own Son to bear the penalty of transgression so that sinners might be restored to His favor and brought back to their Eden home. The great controversy, which began in heaven, was to be decided in the very world, on the same field, that Satan claimed as his.BOE 25.2

It was amazing to all the universe that Christ would humble Himself to save fallen men and women. When Christ came to our world in the form of humanity, all were intensely interested in following Him as He traveled the blood-stained path from the manger to Calvary. Heaven noted the insult and mockery that He received and knew that it was at Satan’s instigation. They watched the battle between light and darkness as it grew stronger. And as Christ cried out upon the cross “It is finished!” (John 19:30), a shout of triumph rang through every world and through heaven itself. The great contest was now decided, and Christ was conqueror. His death answered the question whether the Father and the Son had sufficient love for the human race to exercise self-denial and a spirit of sacrifice. Satan had revealed his true character as a liar and murderer. With one voice the loyal universe united in praising the divine administration.BOE 25.3

But if the law was abolished at the cross, as many claim, then the agony and death of God’s dear Son were endured only to give to Satan just what he wanted; then the prince of evil triumphed, and his charges against the divine government were sustained. The fact that Christ bore the penalty for human disobedience is a mighty argument that the law is changeless; that God is righteous, merciful, and self-denying; and that infinite justice and mercy unite in the administration of His government.BOE 25.4
