For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. Matthew 5:18. TDG 14.1
When Christ entered upon His campaign, Satan met Him and contested every inch of ground, exerting his utmost powers to conquer Him. Much was involved in this controversy. Intense interests were at stake. The questions to be answered were: “Is God's law imperfect, in need of being amended or abrogated? or is it immutable? Is God's government stable? or is it in need of changes?” Not only before those living in the city of God, but before the inhabitants of all the heavenly universe, were these questions to be answered.... TDG 14.2
From the manger to the cross Satan followed the Son of God. Temptations beat upon Him like a tempest. But the more fierce the conflict, the more familiar He became with the temptations wherewith man is beset, and the better prepared He was to succor the tempted. TDG 14.3
The severity of the trial through which Christ passed was proportionate to the value of the object to be gained or lost by His success or failure. Not merely the interests of one world were involved. This world was the battlefield, but all the worlds that God has created were affected by the result of the conflict.... Satan sought to make it appear that he was working for the liberty of the universe. Even while Christ was on the cross, the enemy was determined to make his arguments so varied, so deceptive, so insidious, that all would be convinced that God's law was tyrannical. He himself laid every scheme, planned every evil, inflamed every mind to bring affliction on Christ. He himself instigated the false accusations against One who had done only good. He himself inspired the cruel deeds that added to the suffering of the Son of God—the pure, the holy, the innocent. TDG 14.4
By this course of action Satan has forged a chain by which he himself will be bound. The heavenly universe will bear witness to the justice of God in punishing him. Heaven itself saw what heaven would be, if he were in it.... TDG 14.5
Not merely in the minds of a few finite creatures in this world, but in the minds of all the inhabitants of the heavenly universe, has the immutability of God's law been established.... With one voice they extolled God as righteous, merciful, self-denying, just.—Manuscript 1, January 6, 1902, , “God's Justice.” TDG 14.6
