The seriousness of throwing over hell whilst still clinging to the Atonement is obvious. If there is no punishment for sin there can be no self-forgiveness for it. If Christ paid our score, and if there is no hell and therefore no chance of our getting into trouble by forgetting the obligation, then we can be as wicked as we like with impunity inside the secular law, even from self-reproach, which becomes mere ingratitude to the Savior. On the other hand, if Christ did not pay our score, it still stands against us; and such debts make us extremely uncomfortable. The drive of evolution, which we call conscience and honor, seizes on such slips, and shames us to the dust for being so low in the scale as to be capable of them. The ‘saved’ thief experiences an ecstatic happiness which can never come to the honest atheist: he is tempted to steal again to repeat the glorious sensation. But if the atheist steals he has no such happiness. He is a thief and knows that he is a thief. Nothing can rub that off him. He may try to sooth his shame by some sort of restitution or equivalent act of benevolence; but that does not alter the fact that he did steal; and his conscience will not be easy until he has conquered his will to steal and changed himself into an honest man.
– George Bernard Shaw
