Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations! 13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north
[The Great Controversy pp 492] 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.
It is impossible to so explain the origin of sin as to give a reason for its existence. Yet enough may be understood concerning both the origin and the final disposition of sin, to fully make 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 nowise 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.
Ezekiel 28:15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee. 16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
May The Lord add His blessing to the study of His word. God bless!
