Lucifer Is Given Time to Develop His Principles

God in His wisdom did not immediately thrust Satan out of heaven. This act would not have changed his principles, and would only have strengthened his rebellion, for it would have created sympathy for him as one unjustly dealt with; and he would have carried a much larger number with him. He must be displaced, and have time to more fully develop his principles.—The Review and Herald, March 9, 1886.TA 37.1

Satan complained of the supposed defects in the management of heavenly things, and sought to fill the minds of the angels with his disaffection. Because he was not supreme, he sowed seeds of doubt and unbelief. Because he was not as God, he strove to instill into the minds of the angels his own envy and dissatisfaction. Thus the seeds of alienation were planted, afterward to be drawn out and presented before the heavenly courts as originating, not with Satan, but with the angels. So the deceiver would show that the angels thought as he did....TA 37.2

That which Satan had instilled into the minds of the angels—a word here and a word there—opened the way for a long list of suppositions. In his artful way he drew expressions of doubt from them. Then, when he was interviewed, he accused those whom he had educated. He laid all the disaffection on the ones he had led.—The Review and Herald, September 7, 1897.TA 37.3

He [Lucifer] began to insinuate doubts concerning the laws that governed heavenly beings, intimating that though laws might be necessary for the inhabitants of the worlds, angels, being more exalted, needed no such restraint, for their own wisdom was sufficient guide.—Patriarchs and Prophets, 37.TA 38.1

Lucifer ... sought to abolish the law of God. He claimed that the unfallen intelligences of holy heaven had no need of law, but were capable of governing themselves and of preserving unspotted integrity.—The Signs of the Times, April 28, 1890.TA 38.2

Even the loyal angels did not fully discern his [Satan's] character. This was why God did not at once destroy Satan. Had He done so, the holy angels would not have perceived the justice and love of God. A doubt of God's goodness would have been as evil seed that would yield the bitter fruit of sin and woe. Therefore the author of evil was spared, fully to develop his character.—Christ's Object Lessons, 72.TA 38.3
