"When Pompey was killed, Julius Caesar obtained possession of a large casket, which contained a vast amount of correspondence which had been carried on with Pompey. There is no doubt whatever that in that casket there were many letters from certain of Caesar's followers making overtures to Pompey, and had Caesar read those letters it is probable that he would have been so angry with many of his friends that he would have put them to death for playing him false. Fearing this, he magnanimously took the casket and destroyed it without reading a single line. What a splendid way of putting away and annihilating all their offenses against him! Why, he did not even know them, he could not be angry, for he did not know that they had offended. He consumed all their offenses and destroyed their iniquities, so that he could treat them all as if they were innocent and faithful.
The Lord Jesus Christ has made just such an end of your sins and mine. Does not the Lord know our sins, then? Yes, in a certain sense. And yet the Lord declares, 'Their sins and their iniquities will I remember no more.' In a certain sense, God cannot forget. But in another sense, he himself declares that he remembers not the sins of his people but has cast them behind his back. 'The iniquities of Israel,' says he, 'shall be sought for, and there shall be none; and the sins of Judah, and they shall not be found.'
An accusing spirit might have said to Caesar, 'Do you not know that Caius and Florus were deeply involved with your enemy, Pompey?' 'No,' he replies, 'I know nothing against them.' 'But in that casket there is evidence.' 'Ah,' rejoins the hero, 'there remains no casket. I have utterly destroyed it.'"
