Polygamy was practiced at an early date. It was one of the sins that brought the wrath of God upon the antediluvian world. Yet after the Flood it again became widespread. It was Satan’s studied effort to pervert the marriage institution, to weaken its obligations and lessen its sacredness; for in no surer way could he deface the image of God in man and open the door to misery and vice. (PP 338.1) MC VC

From the opening of the great controversy it has been Satan’s purpose to misrepresent God’s character and to excite rebellion against His law, and this work appears to be crowned with success. The multitudes give ear to Satan’s deceptions and set themselves against God. But amid the working of evil, God’s purposes move steadily forward to their accomplishment; to all created intelligences He is making manifest His justice and benevolence. Through Satan’s temptations the whole human race have become transgressors of God’s law, but by the sacrifice of His Son a way is opened whereby they may return to God. Through the grace of Christ they may be enabled to render obedience to the Father’s law. Thus in every age, from the midst of apostasy and rebellion, God gathers out a people that are true to Him—a people “in whose heart is His law.” Isaiah 51:7. (PP 338.2) MC VC

It was by deception that Satan seduced angels; thus he has in all ages carried forward his work among men, and he will continue this policy to the last. Should he openly profess to be warring against God and His law, men would beware; but he disguises himself, and mixes truth with error. The most dangerous falsehoods are those that are mingled with truth. It is thus that errors are received that captivate and ruin the soul. By this means Satan carries the world with him. But a day is coming when his triumph will be forever ended. (PP 338.3) MC VC

God’s dealings with rebellion will result in fully unmasking the work that has so long been carried on under cover. The results of Satan’s rule, the fruits of setting aside the divine statutes, will be laid open to the view of all created intelligences. The law of God will stand fully vindicated. It will be seen that all the dealings of God have been conducted with reference to the eternal good of His people, and the good of all the worlds that He has created. Satan himself, in the presence of the witnessing universe, will confess the justice of God’s government and the righteousness of His law. (PP 338.4) MC VC
