The Origin of Evil

To many minds the origin of sin and the reason for its existence are a source of great perplexity. They see the work of evil, with its terrible results of woe and desolation, and they question how all this can exist under the sovereignty of One who is infinite in wisdom, in power, and in love. Here is a mystery of which they find no explanation. And in their uncertainty and doubt they are blinded to truths plainly revealed in God's word and essential to salvation. There are those who, in their inquiries concerning the existence of sin, endeavor to search into that which God has never revealed; hence they find no solution of their difficulties; and such as are actuated by a disposition to doubt and cavil seize upon this as an excuse for rejecting the words of Holy Writ. Others, however, fail of a satisfactory understanding of the great problem of evil, from the fact that tradition and misinterpretation have obscured the teaching of the Bible concerning the character of God, the nature of His government, and the principles of His dealing with sin. — {GC 492.1} (4SP 316.1)

It is impossible to explain the origin of sin so as to give a reason for its existence. Yet enough may be understood concerning both the origin and the final disposition of sin to make fully manifest the justice and benevolence of God in all His dealings with evil. Nothing is more plainly taught in Scripture than that God was in no wise responsible for the entrance of sin; that there was no arbitrary withdrawal of divine grace, no deficiency in the divine government, that gave occasion for the uprising of rebellion. Sin is an intruder, for whose presence no reason can be given. It is mysterious, unaccountable; to excuse it is to defend it. Could excuse for it be found, or cause be shown for its existence, it would cease to be sin. Our only definition of sin is that given in the word of God; it is “the transgression of the law;” it is the outworking of a principle at war with the great law of love which is the foundation of the divine government. — {GC 492.2} (4SP 316.2)

The entrance of sin into heaven cannot be explained. If it were explainable, it would show that there was some reason for sin. But as there was not the least excuse for it, its origin will ever remain shrouded in mystery. — {RH, March 9, 1886} 

God had a knowledge of the events of the future, even before the creation of the world. He did not make His purposes to fit circumstances, but He allowed matters to develop and work out. He did not work to bring about a certain condition of things, but He knew that such a condition would exist. The plan that should be carried out upon the defection of any of the high intelligences of heaven—this is the secret, the mystery which has been hid from ages. And an offering was prepared in the eternal purposes to do the very work which God has done for fallen humanity. — {ST, March 25, 1897} 

God did not create evil. He only made the good, which was like himself. But Satan would not be content to know the will of God and do it. His curiosity was on the stretch to know that which God had not designed he should know. Evil, sin, and death were not created by God; they are the result of disobedience, which originated in Satan. But the knowledge of evil now in the world was brought in through the cunning of Satan. These are very hard and expensive lessons; but men will learn them, and many will never be convinced that it is bliss to be ignorant of a certain kind of knowledge, which arises from unsatisfied desires and unholy aims. — {RH August 4, 1910, par. 4}
