So when the flood of death swallows up the fruit of mere earthly labours, and the sage and the idiot alike are cast on the shore of eternity bare of all that belonged but to this world, the Word of God will abide for ever, the Christian's best treasure is left to him still. The boys of Duff's school were every day taught pure religion, and their parents were invited to attend during the lesson. One day that lesson was on Charity as described in the Thirteenth Chapter of First Corinthians. "Throughout, all were attentive, and the minds of a few became intensely riveted, while the glistening eye and the changeful countenance reflected as in a mirror the inward thought most clearly. At last when the concluding words of the inspired description of heavenly love was given, 'endureth all things,' a youth who but a few days before had risen to oppose the reading of the Bible, started from his seat exclaiming aloud, 'Oh! Sir! That is too good for us! who can act up to that, who can act up to that.'" A deep impression was made on the mind of one young Hindu from the simple reading of the words that promise blessedness to him who loves and prays for his enemy. For days and weeks the youth could not help crying out, "'Love your enemies, bless them that curse you!' How beautiful! how divine! surely this is the truth!" Duff's explanation of the causes and nature of rain led his bright lads to understand that it neither comes from Indra, nor from a celestial elephant. They felt that they had been too long grossly deceived in matters of science. In some minds there was doubtless a struggle between the new ideas and the old. "What becomes of our Shaster if your account be true?" asked a young Brahman. "The Shaster is true, Brahma is true, and your Gurus must accordingly be false, 'and yet it looks like the truth.'" On the occasion of an eclipse, a true exposition being given of the real cause of the wonder, a very great shock was given to Hindu prejudice. Many of the intelligent lads perceived that the wild tales which they had been told about a monster attacking the sun, were not only false but absurd. The movement going on was one which could not be hidden; Gurus and Brahmans, accustomed to be adored almost as gods, saw that Hinduism itself was in danger. Those whom it had been their interest to keep in darkness, were having their eyes opened. The Brahmans determined to crush the Missionary school. A decree went forth that whoever attended it should be excluded from caste. It was suggested that a yellow flag should be placed before the school to warn all Hindus from entering so dangerous a place.
