"There is superficial conflict but deep concord between science and theistic religion, but superficial concord and deep conflict between science and naturalism."
Alvin Plantinga (Where the Conflict Really Lies: Science, Religion, and Naturalism)

"The existence of God is neither precluded nor rendered improbable by the existence of evil. Of course, suffering and misfortune may nonetheless constitute a problem for the theist; but the problem is not that his beliefs are logically or probabilistically incompatible. The theist may find a religious problem in evil; in the presence of his own suffering or that of someone near to him he may find it difficult to maintain what he takes to be the proper attitude towards God. Faced with great personal suffering or misfortune, he may be tempted to rebel against God, to shake his fist in God's face, or even to give up belief in God altogether. But this is a problem of a different dimension. Such a
problem calls, not for philosophical enlightenment, but for pastoral care. The Free Will Defense, however, shows that the existence of God is compatible, both logically and probabilistically, with the existence of evil; thus it solves the main philosophical problem of evil."
Alvin Plantinga (God, Freedom, and Evil)

if God does not exist and there is no immortality, then all the evil acts of men go unpunished and all the sacrifices of good men go unrewarded. But who can live with such a view? Richard Wurmbrand, who has been tortured for his faith in communist prisons, says,

The cruelty of atheism is hard to believe when man has no faith in the reward of good or the punishment of evil. There is no reason to be human. There is no restraint from the depths of evil which is in man. The communist torturers often said, 'There is no God, no Hereafter, no punishment for evil. We can do what we wish.' I have heard one torturer even say, 'I thank God, in whom I don't believe, that I have lived to this hour when I can express all the evil in my heart.' He expressed it in unbelievable brutality and torture inflicted on prisoners."
