Notwithstanding that Cain had by his crimes merited the sentence of death, a merciful Creator still spared his life, and granted him opportunity for repentance. But Cain lived only to harden his heart, to encourage rebellion against the divine authority, and to become the head of a line of bold, abandoned sinners. This one apostate, led on by Satan, became a tempter to others; and his example and influence exerted their demoralizing power, until the earth became so corrupt and filled with violence as to call for its destruction. (PP 78.1) MC VC

In sparing the life of the first murderer, God presented before the whole universe a lesson bearing upon the great controversy. The dark history of Cain and his descendants was an illustration of what would have been the result of permitting the sinner to live on forever, to carry out his rebellion against God. The forbearance of God only rendered the wicked more bold and defiant in their iniquity. Fifteen centuries after the sentence pronounced upon Cain, the universe witnessed the fruition of his influence and example, in the crime and pollution that flooded the earth. It was made manifest that the sentence of death pronounced upon the fallen race for the transgression of God’s law was both just and merciful. The longer men lived in sin, the more abandoned they became. The divine sentence cutting short a career of unbridled iniquity, and freeing the world from the influence of those who had become hardened in rebellion, was a blessing rather than a curse.

Satan is constantly at work, with intense energy and under a thousand disguises, to misrepresent the character and government of God. With extensive, well-organized plans and marvelous power, he is working to hold the inhabitants of the world under his deceptions. God, the One infinite and all-wise, sees the end from the beginning, and in dealing with evil His plans were far-reaching and comprehensive. It was His purpose, not merely to put down the rebellion, but to demonstrate to all the universe the nature of the rebellion. God’s plan was unfolding, showing both His justice and His mercy, and fully vindicating His wisdom and righteousness in His dealings with evil. (PP 78.3) MC VC

The holy inhabitants of other worlds were watching with the deepest interest the events taking place on the earth. In the condition of the world that existed before the Flood they saw illustrated the results of the administration which Lucifer had endeavored to establish in heaven, in rejecting the authority of Christ and casting aside the law of God. In those high-handed sinners of the antediluvian world they saw the subjects over whom Satan held sway. The thoughts of men’s hearts were only evil continually. Genesis 6:5. Every emotion, every impulse and imagination, was at war with the divine principles of purity and peace and love. It was an example of the awful depravity resulting from Satan’s policy to remove from God’s creatures the restraint of His holy law. (PP 78.4) MC VC

By the facts unfolded in the progress of the great controversy, God will demonstrate the principles of His rules of government, which have been falsified by Satan and by all whom he has deceived. His justice will finally be acknowledged by the whole world, though the acknowledgment will be made too late to save the rebellious. God carries with Him the sympathy and approval of the whole universe as step by step His great plan advances to its complete fulfillment. He will carry it with Him in the final eradication of rebellion. It will be seen that all who have forsaken the divine precepts have placed themselves on the side of Satan, in warfare against Christ. When the prince of this world shall be judged, and all who have united with him shall share his fate, the whole universe as witnesses to the sentence will declare, “Just and true are Thy ways, Thou King of saints.” Revelation 15:3. (PP 79.1) MC VC

It was necessary that this sin should be punished, as a testimony to surrounding nations of God’s displeasure against idolatry. By executing justice upon the guilty, Moses, as God’s instrument, must leave on record a solemn and public protest against their crime. As the Israelites should hereafter condemn the idolatry of the neighboring tribes, their enemies would throw back upon them the charge that the people who claimed Jehovah as their God had made a calf and worshiped it in Horeb. Then though compelled to acknowledge the disgraceful truth, Israel could point to the terrible fate of the transgressors, as evidence that their sin had not been sanctioned or excused. (PP 325.1) MC VC

Love no less than justice demanded that for this sin judgment should be inflicted. God is the guardian as well as the sovereign of His people. He cuts off those who are determined upon rebellion, that they may not lead others to ruin. In sparing the life of Cain, God had demonstrated to the universe what would be the result of permitting sin to go unpunished. The influence exerted upon his descendants by his life and teaching led to the state of corruption that demanded the destruction of the whole world by a flood. The history of the antediluvians testifies that long life is not a blessing to the sinner; God’s great forbearance did not repress their wickedness. The longer men lived, the more corrupt they became. (PP 325.2) MC VC

So with the apostasy at Sinai. Unless punishment had been speedily visited upon transgression, the same results would again have been seen. The earth would have become as corrupt as in the days of Noah. Had these transgressors been spared, evils would have followed, greater than resulted from sparing the life of Cain. It was the mercy of God that thousands should suffer, to prevent the necessity of visiting judgments upon millions. In order to save the many, He must punish the few. Furthermore, as the people had cast off their allegiance to God, they had forfeited the divine protection, and, deprived of their defense, the whole nation was exposed to the power of their enemies. Had not the evil been promptly put away, they would soon have fallen a prey to their numerous and powerful foes. It was necessary for the good of Israel, and also as a lesson to all succeeding generations, that crime should be promptly punished. And it was no less a mercy to the sinners themselves that they should be cut short in their evil course. Had their life been spared, the same spirit that led them to rebel against God would have been manifested in hatred and strife among themselves, and they would eventually have destroyed one another. It was in love to the world, in love to Israel, and even to the transgressors, that crime was punished with swift and terrible severity. (PP 325.3) MC VC
