It is not mentioned in their 'Science' that God can take human form; so how can they believe it? There are such men indeed!
Listen to a story. A man said to his friend, "I have just seen a house fall down with a terrific crash." Now, the friend to whom he told this had received an English education. He said: "Just a minute. Let me look it up in the newspaper." He read the paper but could not find the news of a house falling down with a crash. Thereupon he said to his friend: "Well, I don't believe you. It isn't in the paper; so it is all false."
