Those who have chosen Satan as their leader are not prepared to enter the presence of God. Pride, deception, immorality, cruelty, have become established in their characters. Can they enter heaven to live forever with those whom they hated on earth? Truth will never be agreeable to a liar. Meekness will not satisfy self-esteem. Purity is not acceptable to the corrupt. Unselfish love does not appear attractive to the selfish. What enjoyment could heaven offer those who are focused on selfish interests? LF 221.6
Will those whose hearts are filled with hatred of God, of truth and holiness, be able to mingle with the inhabitants of heaven and join their songs of praise? God granted them years of grace to prepare for eternity with Him, but they never trained the mind to love purity. They never learned the language of heaven. Now it is too late. LF 221.7
A life of rebellion against God has made them unfit for heaven. Its purity and peace would be torture to them; the glory of God would be a consuming fire. They would long to escape from that holy place and would welcome destruction, just to be hidden from the face of Him who died to redeem them. It is their own choice that decides the destiny of the wicked. They voluntarily exclude themselves from heaven, and God is just and merciful in ratifying their choice. Like the waters of the Flood, the fires of the great day declare God's verdict that the wicked are incurable. They have exercised their will in revolt. When life is over, it is too late to turn their thoughts from law-breaking to obedience, from hatred to love. LF 221.8
