Disaffection began in heaven because Satan could not have the place he coveted. Disaffection and distrust had never before entered any heart. When Satan began his evil work, he did not himself see where it would lead. But the thoughts he entertained after a time were expressed in suggestions of evil, and these, diffused among the angels, led to the great rebellion which was the beginning of all the woe and misery that has befallen mankind. (UL 114.3) MC VC
