Like the waters of the Flood the fires of the great day declare God’s verdict that the wicked are incurable. They have no disposition to submit to divine authority. Their will has been exercised in revolt; and when life is ended, it is too late to turn the current of their thoughts in the opposite direction, too late to turn from transgression to obedience, from hatred to love. (GC 543.1) MC VC

In sparing the life of Cain the murderer, God gave the world an example of what would be the result of permitting the sinner to live to continue a course of unbridled iniquity. Through the influence of Cain’s teaching and example, multitudes of his descendants were led into sin, until “the wickedness of man was great in the earth” and “every imagination of the thoughts of his heart was only evil continually.” “The earth also was corrupt before God, and the earth was filled with violence.” Genesis 6:5, 11.

In mercy to the world, God blotted out its wicked inhabitants in Noah’s time. In mercy He destroyed the corrupt dwellers in Sodom. Through the deceptive power of Satan the workers of iniquity obtain sympathy and admiration, and are thus constantly leading others to rebellion. It was so in Cain’s and in Noah’s day, and in the time of Abraham and Lot; it is so in our time. It is in mercy to the universe that God will finally destroy the rejecters of His grace.
